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.)

SEQUENTIALLY-PRESENTED SKILLS AND RELATED ACTIVITIES

Open-Ended Clove Hitch – How else would you want to secure the hand ropes to the A-frames? — How-to Video / Activity Video

Using Half Hitches to tie a Clove Hitch – A simple process always makes it easy to tie a clove hitch and finish many types of lashings. Several are used to attach the spanner ropes. — How-to Video / Activity Video —

Round Lashing – Three or four can be used to join together the bottoms of the A-frames on each side. Round lashings can also be used to attach a flag pole(s) to an A-frame(s). — How-to Video / Activity Video

Square Lashing – This project can use fourteen of them for both building the A-frames and then joining them together. — How-to Video / Activity Video

3-2-1 Anchor – The skill is to carefully drive in the stakes at the proper angle and applying the tourniquets to join the groupings. — Explanatory Video

Roundturn with Two Half Hitches – You can use this pioneering knot to attach the hand ropes to the anchors. — How-to Video / Activity Video —

Butterfly Knot and Rope Tackle – This configuration can be used to adjust the tension on the foot rope. — How-to Video 1, How-to Video 2 / Activity Video
