Simple Camp Table

This small camp table can be comprised almost completely of Scout staves. It’s 100% functional and provides a convenient raised surface for personal, patrol, or general use. It’s simple design makes it quick and easy to set up, and it is remarkably stable.

Make the table legs. Start by lashing together four Scout staves into two sets of shear legs with 6-foot manila lashing ropes. If you prefer, square lashings can be used instead of shear lashings. (In lieu of Scout staves, straight poles an inch or so in diameter are just fine.)

Lash on the table top supports. Next, with two square lashings, lash a 2-1/2-foot stick to connect each set of shear legs about 30 inches off the ground. (A Scout stave cut in two is ideal.)  This will form two A-frames, one for each side of the table. Make sure each of these support sticks are lashed on straight and at the same distance from the bottom end of both sets of legs.

Securely hold up the A-frames. This is surely the best part. Find the midpoint of a 20-foot line. At about two feet away, tie a clove hitch at the top of one of the Scout staves of one of the A-frames. Repeat this process on the other side attaching the line with a clove hitch to one of the Scout staves of the other A-frame.

Secure each end of the 20-foot line to stakes driven into the ground on either side, about 5 feet away, so the line extends out evenly from each end of this table framework. You can use round turns with two half hitches, taut-line hitches, or rope tackles. Here’s the beauty of this configuration: you can manipulate the distance between the A-frames by adjusting the clove hitches, and provide optimum stability to the table by placing a good, reasonable strain on the line at each stake. It will stand up in an impressively rigid fashion.

Lash on the table top. Finally, lay 12 Scout staves, (or similar poles) side by side, on top of the 2-1/2-foot support sticks, and using binder twine, lash them on with floor lashings.

Sequential Programming: Monkey Bridge


Troop 86 from Sumter, SC wanted to do a pioneering project and they selected the Double A-Frame Monkey Bridge. Great place to start, and a great way to illustrate sequential programming. What skills enter into the picture? A whole bunch! And with each step along the way, there’s an activity wherein each campcraft skill can be put into action, in a fun way, as reinforcement.

B.-P. wrote: “I am inclined to suggest to Scouters that in addition to the technical details of knotting, lashing, and anchorages, there is an educative value in Pioneering since it gives elementary training in stresses, mensuration, etc.” In addition to the “mensuration” skills that come into play when setting out the area for the bridge’s A-frames and anchors, a good deal of measuring takes place to assure the A-frames are as close to identical as possible, the pairs are joined together in similar fashion, an the spanner ropes are spread evenly. (Hand in hand with the building, Scouts do a lot of planning.)

Skylon “Floating” Flagpole

SkylonFlagpole2

A flagpole suspended off the ground by a series of lines, so that it appears to be floating, can be a really neat project. The structural principle has been referred to as tensegrity, and is based on using one half the lines to lift the pole off the ground, and the other half to give it stability, supporting it in a vertical position. On occasion, Scouts choose to use more than three upright support poles, but just like with a simple flagpole employing three supporting guy lines, three upright poles provide the required balance needed to hold the pole up straight. The longer the support poles, the higher off the ground the flagpole can go.

SkylonGroup
The Crew

There are many ways Scouts go about constructing  a suspended flagpole. The following materials were used for this particular flag display:

  • one 20-foot bamboo pole (flagpole)
  • three 10-foot x 3-inch pine spars (upright support poles)
  • nine pieces of rebar, sawed to 3 feet each
  • six 50-foot lengths of 3/8-inch manila (guy lines)
  • three 3/8-inch double pulley blocks
  • 50-foot length of 1/4-inch braided nylon (for the halyard) along with a couple of clips
  • metal ring
  • six pioneering stakes
  • wooden mallet (for driving in the stakes)
  • club hammer (for driving in the rebar)
  • roll of friction tape
  • lengths of 1/4-inch braided nylon cord
  • binder twine

The following initial steps were taken for this particular flag display:

  1. SkylonPully
    Double Pulley Block and Tackle

    Where the flagpole will be placed, 9 feet from the center of an equilateral triangle, three holes are made, 4 inches in diameter and 2 feet deep.

  2. A double pulley is securely tied to the top of each 10-foot support pole and a 50-foot guy line is reeved through each sheave.
  3. A 10-foot upright support pole is planted in each hole which is packed with excavated material. Three lengths of rebar are pounded in around each spar.
  4. A span of friction tape is applied to the areas of the 20-foot flagpole, where the lines will be tied (bamboo is slick)
  5. The metal ring is tied to the tip of the 20-foot pole and the halyard is threaded through.
  6. A 1-1 anchor is installed about 9 feet behind each 10-foot spar
SkylonMasthead
Jury Mast Knot Applied over Friction Tape

The following rigging procedure was followed for this particular flag display:

  1. A tight jury mast knot (#1168 in The Ashley Book of Knots) is applied over the friction tape at the bottom and 4 feet from the top of the flagpole.
  2. The guy lines from each upright support pole are tied to corresponding loops in the jury mast knots at the top and bottom of the flagpole with two half hitches, the tail of which is tightly seized to the standing part using binder twine with a West Country Round Lashing.

The following procedure was followed to raise and support this particular flag display:

  1. Skylon 1-1
    1-1 Anchor

    When the flagpole is rigged and everything is in place, two or more Scouts lift up the pole in the center of the triangle, and hold it erect.

  2. One Scout mans each lifting guy line tied to the bottom of the pole. On signal, they all pull these lifting lines until the strain assumed by the Scouts holding the pole erect is replaced by the lower, lifting guy lines.  (Note: If the pole is taller or heavier, an additional Scout needs to man each guy line attached to the top, in order to stabilize the pole as it’s being held up, keeping it from tilting or falling. However, tension is only applied to offset any overt tilting.)
  3. SkylonTop
    Top Stabilizing Guy Lines

    When the lifting guy lines have taken up the strain to hold the flagpole at the desired height (about half the length of the upright support poles protruding from their holes), a butterfly knot is applied at the appropriate place and they are secured to the 1-1 anchor with a rope tackle.

  4. When the lower guy lines are well secured, the upper, stabilizing guy lines can be adjusted so that the flagpole is held up in a straight position. When the flagpole is even, the upper lines in turn are secured to their respective anchors with a rope tackle.

 

14′ Climbing Tower at Scout Camp

14' Double Ladder Signal Tower
14′ Double Ladder Signal Tower

Before the advent of BSA height restrictions on pioneering projects, the boy-sized, 14′ Double Ladder Signal Tower was built by Scout units, Scout pioneering crews, and Pioneering Merit Badge classes on a regular basis.

Because it’s such a fine example of Scout Engineering, it has continued to be a feature in the Pioneering Areas of the national jamborees.

At this time, with the proper consideration and review from the Council Risk Enterprise Management Committee, in conjunction with the assurance the construction process will be carried out correctly and in accordance with pioneering safety guidelines, a structure like this that is taller than 6 feet can once again be built and climbed upon during Boy Scout summer camp.

The materials and assembly instructions as per the project’s designer, Adolph Peschke, can be found here.

The photos of these Scouts were taken last week during their Pioneering Merit Badge class at summer camp.

Scout Swing

12' Scout Swing Seeing Action at a Public Scout Expo
12′ Scout Swing Seeing Action at a Public Scout Expo

This is a simple project that is bound to get lots of play. Therefore, lashings need to be super tight, and eight sturdy pioneering stakes will serve as anchors and need to be driven solidly into the ground, perpendicular to and touching the six spars connecting the legs.

List of Materials

  • six 3-1/2-inch x 12-foot spars for the legs
  • one 4-inch x 12-foot spar for the crossbar
  • six 3-inch x 6-foot connecting spars
  • eight 3-foot pioneering stakes
  • two 2-inch x 8-inch x 2-foot prepared swing seats
  • four 20-foot x 1/2-inch swing ropes
  • four steel rings
  • four 6-foot x 5/8-inch ropes for Prusiks
  • twenty 15-foot x 1/4-inch manila lashing ropes
  • six 20-foot x 1/4-inch manila lashing ropes
  • two single pulleys reeved with 20 feet of rope, with a small loop of rope tied to the top
  • one eight-foot ladder

Though one might think this structure is built by making two simple tripods to support the crossbar, it’s MUCH better to make two A-frames, standing up vertically, supported by a third spar lashed to one leg of each A-frame, slanting down to the ground. The obvious reason is to give the crossbar maximum stability where it rests at the juncture of the two legs of each vertical A-frame.

Prepared Swing Seats
Prepared Swing Seats

Rig the swing seats. Attach two 20 foot swing ropes to the two swing seats, using a scaffold hitch rigged with a Bowline. In order to accommodate the swing rope with the Scaffold Hitch, the swing seats should be prepared with impressions cut on each side, 2″ long and 1/2″ deep, beginning 1-1/2″ from each end.

Link to: Larger ViewAttach the rings to the crossbar. Using the 6-foot ropes, tie the steel rings to the crossbar with prusiks at intervals as per the measurements reflected in the diagram.

Prepare the A-Frames. Using two 12-foot spars and one 6-foot spar, with tight square lashings, lash together two identical A-frames making sure the tips of the legs cross the same distance from the top for each. Use a 20-foot rope where the tips of the legs intersect, and 15-foot ropes at the bottom. NOTE: Make sure the 6-foot connecting spars are lashed low enough to the bottom so later on there will be plenty of room to lash them to the pioneering stakes.

Add the oblique supporting legs. About a foot or so below the top lashing on the A-frames, lash on a third 12-foot spar to one leg of each A-frame, using 20-foot ropes. These spars will be angled down, extending out to support the A-frames in their vertical positions.

Connect the legs. Stand up the A-frames so they’re in a vertical position. Connect the 12-foot oblique supporting leg to the legs of each A-frame, using the remaining 6-foot spars and eight 15-foot ropes. Again, make sure they’re lashed low enough to the ground so later on there will be plenty of room to lash them to the pioneering stakes. (If you’ll be using the pulleys to lift up the 12-foot crossbar, loop one over the top of a leg, before standing up the A-frames.)

Position the two 3-legged subassemblies. Line up both support assemblies so they are facing one another on even ground and with the A-frames 10 feet apart.

Position the crossbar. Tie one end of each pulley rope to the ends of the crossbar, and have two Scouts carefully hoist the crossbar up to near the tops of the A-frames. They must carefully hold it in place. Position the ladder so that it’s even with one A-frame, and have a strong Scout climb about four to five feet up and lift the end into the crux of one A-frame. Repeat the process on the other side of the swing.

Lash on the crossbar. Making sure the rings are properly hanging down, and the crossbar is extending out approximately one foot from each side, one Scout will climb up and tightly lash the crossbar to one of the legs of each A-frane with a 20-foot rope.

Tie on the swings. One Scout will climb up and connect the swing ropes to the rings using a roundturn with two half hitches, making sure the swings hang evenly at the desired height.

Drive in and lash on the anchors. Four pioneering stakes are driven into the ground on each side—two spaced evenly and touching the bottom of each A-frame, and one against each connecting spar, hammered in near the oblique supporting leg. After these stakes are solidly in the ground, so they cannot jiggle, lash them to the connecting spars using 15-foot ropes.

Test the swing and make any adjustments as necessary.

UNDERWATER See-Saw
UNDERWATER See-Saw

We were introduced to and adapted this project thanks to the great Pioneering Made Easy website. It was inspired by Fun With Ropes and Spars by John Thurman who, with his inimitable approach to providing pioneering challenges and robust Scouting activities, dubbed it the “Underwater See-Saw.” This version is a doable land approach that can be erected during a camping trip (where the materials are trailered in) or along side a Double A-frame Monkey Bridge as part of a simple, public demonstration of Scouting fun. Because of the size and weight of the materials required for its construction, it’s categorized under Involved Campsite Improvements, but when the smoke clears, what we’ve got here is a large campsite toy that’s relatively easy to build. Link to: Larger ViewWe’ll need:

  • 4     10′ x 4″ leg spars
  • 2     6′ x 3″ leg supports
  • 2     2′ to 3′ x 3″ roller supports
  • 3     2′ to 3′ x 2″ connectors
  • 1     6′ x 4-1/2″ roller spar
  • 1     10′ x 10″ x 2″ smooth plank
  • 12   15′ x 1/4″ lashing ropes
  • 4     20′ x 1/4″ lashing ropes for the roller supports
  • 1     35’ x 1/4″ lashing rope for the plank
  • 4     25′ x 3/8″ guy lines
  • 2     old tires
  • 8    30″  pioneering stakes

Note: In building the see-saw, the premise is to space the A-frames, the roller supports and the two bottom connectors so that the 6′ roller spar can easily roll around, but can hardly move from side to side or up and down. Overall, this is a simple project though some precision will be required when positioning the plank at the right height so that riders don’t experience too much tilt. Like with any seesaw, care must be taken not to misuse the structure, but overall this camp seesaw is a tempting attraction and gets a lot of long-time play and attention. When built with care and guyed down securely, it can withstand the frequent use it invariably will get, even from heavier riders.

Tightly Lashing on a Roller Support
Tightly Lashing on a Roller Support

Build the A-frames. The first step is to prepare two matching A-frames using the leg spars and the 6’ leg support spars. You can use a Shear Lashing or a Square Lashing on top, and Square Lashings for the 6′ leg support spars. The main thing is to make sure that with both A-frames, the tops intersect the same distance from the tips and the legs spread apart an equal distance at the butt ends. 8″ up from the bottom and 8″ protruding from the legs is fine, and intersecting a foot from the tips works fine too.

Prepare to connect the A-frames. Stand the A-frames up so that the legs and support spars are parallel, about four and a half inches apart. Since the roller spar will eventually be rotating between the A-frames, the actual distance the A-frames are apart is determined by the diameter of the roller spar. Four Scouts should hold the A-frames upright and steady.

The Roller Bar has to take all the weight, in this case over 550 lbs.
The roller supports have to take all the weight, (in the above photo over 550 lbs. Click on the photo for larger image.)

Lash on the roller support spars. Measure about 30″ up from the butt ends of all four legs. (For smaller, shorter riders, a lower height is definitely advised.) The height of the roller support spars will determine the angle of the board. Too steep an angle could easily make riding precarious. Begin connecting the two A-frames by lashing on the roller supports with tight Square Lashings. Lash them to the outside of the legs at a distance just a fraction wider than the diameter of the roller spar. For neatness, space them so the ends extend an equal distance out from the A-frame legs. Becuase these roller supports will be bearing the weight of the heavy roller spar, the plank, and the Scouts playing on the see-saw, when lashing them on with a Japanese Mark II Square Lashing, start the lashing by tying a Constrictor Knot around the leg to minimize any slippage.

Lash on the lower connectors. With the A-frames held steadily upright, temporarily lay the 6′ roller spar on top of the supports. Using the diameter of the 6′ roller spar as a measure, continue to connect the two A-frames by lashing on two connectors at a distance just above the roller spar, with tight square lashings. Again, for neatness, space them so the ends extend an equal distance out from the A-frame legs. Remove the roller and set it aside.

Lash on the top connector. Lash the last connector to one of the legs at the top of each A-frame, just below where the legs cross, with tight Square Lashings. If there is difficulty reaching the point on the legs where this connector needs to be lashed, carefully lay both parallel A- frames on their sides and then lash the connector in place. Again, for neatness, space the connector so the ends extend an equal distance out from the A-frame legs.

A Seesaw with a Plank (12′) That was a Little too Long!

Make the Anchors. Build four 1-1 Anchors 45º out from each leg.

Attach the guy lines. With a Roundturn with Two Half Hitches, or Rolling Hitches, tie on the 4 guy lines, one each about two feet below the Square Lashings at the top of the A-frames. Connect each to its respective anchor.

Position the see-saw. Stand up and move the A-frames in the position you want the see-saw. Drive in each of the four pioneering stakes, fifteen feet away and 45 degrees out from where they’re tied to the legs of the A-frames. Connect a guy line to each using a Roundturn with Two Half Hitches or rope tackle.

Lash on the plank. Slide the roller spar on top of the roller supports. Lay the plank on top of the roller and using the 35′ lashing rope, lash the middle of the plank firmly in place with a Square Lashing.

Lay down the tires. On each side, at the point where the plank hits the ground, place a tire to cushion the impact and absorb the shock.

Some advisories and suggestions:

  • Seesaws can be hazardous. Make sure there’s no horseplay. Just seated cooperation.
  • When Riders take their places on the board, they should position themselves so their weight is balanced.
  • Riders should never kick off from the ground forcefully springing their side skyward which can easily unbalance the other rider.
  • Exiting the seesaw should only be done when both rider’s feet are on the ground.
  • Adding ropes for handholds can be done in various places along the board by drilling holes about two inches from each edge and threading a short length of 3/8″ to 1/2″ braided nylon or polyester and tying a couple of figure eight stopper knots or tying the ends together on the underside of the board with a Water Knot.
  • Making four indentation grooves in the plank where it will be Square Lashed to the roller bar will eliminate the plank slipping towards one or the other rider during use.

Large Camp Table

The Drawing
The Drawing

A design for this table has been on the drawing board for quite some time. Well, a day before the site was set up for a special Scout Campcraft program, it was decided to build one as a functional showpiece.

The Table WIth Flags a-Blowin'.
The Table WIth Flags a-Blowin’.

We sank four 6′ spars two feet into the ground for the main corners, and sank eight 4′ spars a foot into the ground for the rest of the upright supports. Between the corners we lashed two 10′ lateral spars, and for the two long benches and the sides of the table top, we used six-footers. The table top itself was comprised of 4′ platform spars, and the side seats, 3′ ladder rungs. Since the 10′ lateral spars were really too long, we compensated for the unexpected space between the 6′ bench spars and the ends of the ten-footers by dispensing with the back rests, and instead lashed on a flag at each corner.

The Large Camp Table for the Frontier Days Program
The Large Camp Table for the Frontier Days Program (Click on the image for a LARGER VIEW.)

What a piece of work! It stayed up for three weeks and repeatedly got plenty of heavy use on a daily basis. The Floor Lashings regularly needed adjusting, and served as a perfect location to pass on the Double Floor Lashing technique to program participants who applied it later to building rafts. The 4′ vertical uprights soon worked themselves to a slight wiggling state, but continued to furnish their necessary support. Also, during the three week period, due to the heavy adults who loved to seat themselves at this rather elaborate piece of camp furniture, occasionally various Square Lashings had to be tightened up as well. Nevertheless, with all the strain, rain, and wear, this version of the large camp table happily stayed intact.

Six Flag Banner Gateway

The concept for this gateway originated from the bamboo version placed at one end of Peschke Field at the 2013 national jamboree. Just like the name describes, this gateway flies a banner in the middle surrounded on each side by three flags. Each side is in the shape of a standing triangular prism. If the legs of each prism were far enough apart, symmetrical, and proficiently lashed, the structure could easily be self-standing. However in this instance, we’re using long, thin, yellow pine spars with unequal diameters and with an array of curves. So for stability, the gateway definitely needs to be guyed down at the front and back (outside) legs of each side!

Six Flag Banner Gateway: From the Drawing Board to the Open Field
Six Flag Banner Gateway: From the Drawing Board to the Open Field

To sport a ten foot banner and fly six 3 x 5-foot flags, a gateway like this conceivably can span as little as 20 to 24 feet. The dimensions of the above gateway are purposely larger, employing 8-foot spars to connect the legs, separated by two 14-foot center spars, so the width is closer to 30 feet. Since this project:

  1. is not designed for climbing
  2. relies on four guy lines to keep it erect
  3. is fairly long and wide which can make hoisting a bit of a challenge

most of the spars can be thinner, lighter-weight pine. (Bamboo would be much better!) Naturally, the two triangular prisms should be bottom-heavy, so lash thicker, heavier connector spars at the bases of each side.

Here’s a list of materials:

  • six 8-foot x 3-inch bottom leg connector spars
  • twelve 8-foot x 2-inch middle and top leg connector spars
  • two 14-foot x 2-1/2-inch center spars
  • four 16-foot x 3-inch front and back (outside) leg spars
  • two 18-foot x 3-inch middle leg spars
  • eight rings or small pulleys
  • eight 3-foot cords to attach rings or pulleys
  • eight 40-foot x 1/4-inch braided nylon ropes for halyards
  • eight lightweight carabiners for the flags and banner
  • forty 15-foot x 1/4-inch manila lashing ropes
  • four 6-foot straight spars for right and left front and rear flagpoles (optional)
  • two 8-foot straight spars for right and left middle flagpoles (optional)
  • twelve lashing ropes for round lashings to attach flagpoles to the tops of the legs (optional)

One key to building this gateway is to connect the middle and front leg of each prism shape with three leg connector spars, while both legs are lying flat on the ground. Once connected, the connector spars for the rear legs can be attached to the front and middle legs, after which the rear legs themselves can be held in position and lashed.

On the left: lashing on the the lateral support spars to the middle and front legs that will connect the rear leg. On the right: lashing on the rear leg to form the right triangular prism.
On the left: lashing on base connecting spars to the middle and front legs of the right triangular prism. On the right: lashing on the rear leg to form the right triangular prism.

Another key to constructing the gateway is marking the positions on each leg, measuring up from the butt ends, where the connector spars will be lashed. The intent is to assure they’re evenly-spaced, parallel to one another and perpendicular to the legs.

After the center spars are lashed to the right and left middle legs, and when all the rings and halyards for the flags and banner are tied in the proper positions, the structure is hoisted  from the back using the four guy lines attached to the outside legs of both prisms (with rolling hitches or roundturns with two half hitches), and three hauling ropes attached to the top center spar with draw hitches. Refer to:“Hoisting the Tower”

All Hands on Deck to Hoist the Gateway
All Hands on Deck to Hoist the Gateway

The final step before securing the guy lines to 1-1 anchors with rope tackles is to rotate each prism so that the front and back legs (outside) of each are positioned out at an equal distance from the middle legs.

A Smaller Double Tripod Chippewa Kitchen for a Single Patrol

Basically, this is a mini version of the full-sized Double Tripod Chippewa Kitchen. Same procedure, just scaled down, and a perfect fit for one patrol.  The only things different here are the dimensions:

  • two 6-foot x 2-1/2 to 3-inch platform support spars
  • six 6-foot x 2-inch tripod leg spars
  • four 4-foot x 2-inch rear tripod braces
  • two 4-foot x 2-1/2 to 3-inch front tripod braces (to support the platform support spars)
  • fifteen to twenty 3-foot x 2-inch floor spars (depending on the size of the cooking surface required)
  • sixteen 15-foot x 1/4-inch manila lashing ropes for square lashings (12-1/2′ lashing ropes work well if you have them.)
  • two 20-foot x 1/4-inch manila lashing ropes for tripod lashings
  • binder twine for floor lashing
  • piece(s) of burlap or canvas to cover cooking platform (unless you’re using clay)
It's obvious the patrol is ready to foil cook their lunches before the coals are ready!
It’s obvious the patrol is ready to foil cook their lunches before the coals are ready!

Note: When lashing on the tripod braces, position the two rear ones as low as possible. This way the thicker front one can be lashed on unencumbered, and also placed at the right height. When it comes to adding the two platform support spars you have a choice: lash them both on either the outside or on the inside of the front (outer) tripod legs. In these photos, they’re lashed on the inside.

Catapults at the Jamboree

Soldiers play with Large Catapult
Soldiers play with the “giant” Catapult

Before the Pioneering Area catapults were all completed and positioned in readiness for the thousands of jamboree participants who would be hiking up to Garden Ground Mountain, a little change of pace occurred which translated into a memorable moment. One morning during the building process, some soldiers passing though our area were attracted to the “giant” catapult with the heavy wooden counter weights, double throwing arm, and trebuchet-style swing extension. They were tempted to give it a try and what followed was a scene featuring modern day warriors coupled with ancient weaponry. (Click on the photo for a larger view.)

In addition to the “giant” catapult, three other catapult designs were featured up on Garden Ground Mountain in the pioneering area. Eventually, they were positioned on the far side of Peschke Field, facing a clear expanse of ground which was sectioned off to serve as a shooting area.

Periodically, to the amusement and awe of onlookers and those passing by, the 10′ Double A-Frame Trebuchet with a 200 pound counter weight would launch a large monkey fist in a high arc far down the length of the firing range.

Scouts load the smaller, counter-weighted catapult and launch their shot by pulling together to snap the arm up.

The most excitement from the jamboree catapults was generated during Sunday’s Jambo-palooza festivities. A specially-built 8′ trebuchet was prepared, transported from Garden Ground, and set up at the stadium in Summit Center where it fired water balloons into throngs of Scouts gathered down range waiting to get doused. And, when it was apparent that a T-shirt was to be launched, the ensuing scrambling to catch it or grab it was over the top! (Click on the photo for a larger view.)

Of the four display towers featured in Peschke Field at the 2013 National Jamboree, the Stilt Tower was the second to be constructed, hoisted, and anchored. It gets it’s name because it stands on only two legs, and hence it’s dependence on four essential guy lines to hold it up.

The tower presented somewhat of a building challenge to the crew assigned to undertake the task. They had never built one before, and all they were given was a drawing and a sketchy list of materials.

The Stilt Tower exhibit turned out to be both good-looking and novel. For a procedure and instructions refer to Pioneering Made Easy: Stilt Tower.

The Hourglass Tower in the 2013 National Jamboree Pioneering Area was set up as one of four tower displays.

“The Hourglass Tower is something of a classic for Scout pioneering. John Sweet’s excellent book Scout Pioneering describes it, and since then many Scout troops have built one.” (Read: Erecting an Hourglass Tower in Ropes and Poles.)

“The tower is constructed from two large pyramids interlocked together.” (Read: Hourglass Tower in Poneering Made Easy.)

As an interesting side note: by employing rope tackles in each of the lines marrying the two tripods, effectively tightening the connections was very easy to accomplish.

Single A-Frame Bridge Pictorial

The Single A-Frame Bridge is made up of three subassemblies. Please refer to Bridge Walkways as a point of reference for two of the three of these subassemblies. The following photos will enliven the text and instructions featured in Adolph Peschke’s informative, older pioneering merit badge pamphlet. Click on the photos for larger views:

Lashing the top of the legs with a two pole shear lashing. Lashing on the ledger to the bottom of the legs. Lashing on the transom at the desired distance from the butt ends of the legs. All square lashings are lashed tightly, especially on the transom.

Carry the assembled A-Frame to the creek or ravine. Standup the A-Frame in the desired position. Carry over the walkways and place them on the A-Frame’s transom. Connect the underspars of the walkways to  the transom with three strop lashings.
