Plans for Projects We Have Built

Below are plans for other projects that we have built. Once we decide on a new project that we want to build, we make a scale drawing and use this to work out a construction sequence and materials list. The drawings shown below contain very limited information about the safety precautions and construction sequences that we followed when building these projects, and you should treat them only as a starting point for tackling these projects.

Bridges

• 20’ Banana Bridge

• 20’ Single Lock Bridge

• 100’ Suspension Bridge

Towers

• 15’ Brynbach Tower

• Steps for Building a Three-Legged Tower

• 15’ Three Legged Signal Tower

• 40’ Three Legged Signal Tower and Rigging Plan

• 18’ Four Legged Signal Tower

• 20’ Four Legged Signal Tower

• 30’ Four Legged Signal Tower

• Rigging Plan to Erect a 30’ Tower

• 10’ Modified Peschke Ladder Tower

• 20’ Stilt Tower

Other

• 3-Ton Derrick

• Paddlewheel Raft

• Sail Raft

Note: This raft proved very unstable under sail power, but the basic frame works well with paddles if built without the mast.

Here are some other web and print sources that you might find useful.

Web Pages

• Ropesandpoles.blogspot.com

• A blog about Pioneering by a South African Scouter that shows unconventional projects/techniques, a variety of large projects, and large rafts.

• Scoutpioneering.com

• Larry Green’s blog, featuring excellent coverage of basic skills, smaller projects including many camp gadgets, and fun activities for troop meetings and campouts.

• www.makerope.com

• Information about the rope making process for the farmer/ hobbyist and the seller of the hand-cranked rope making machine that we use.

• www.pioneeringprojects.org and Pioneering Projects Big and Small

• Two collections of sketches of Pioneering Projects and Camp Gadgets. A great source of inspiration.

• www.thedump.scoutscan.com

• A group of Canadian Scouters has amassed a collection of Scouting books and pamphlets that have entered the public domain. The John Thurman books linked below come from this web page.

Books and Pamphlets

• FM 5-125 Rigging Techniques Applications & Procedures (Defense Department, 1995)

• Lots of useful information including: knots and splices, working with block and tackles, safe working loads of common ropes and cables, setting up and using gin poles, shear legs, and derricks, types and holding capacities of anchor systems, compressive strength of wooden timbers, calculating forces in guy lines, derricks, and ropeways, and much more.

• John Thurman’s Books

• John Thurman was an English Scouter and camp director who wrote extensively on Pioneering in the 1950s and 1960s. Thurman’s books include skill instruction and sketches and descriptions of dozens of useful and fanciful pioneering projects. Bear in mind when reading Thurman, that he seems not to have built some of the projects that he describes, and some of the sketches in his books defy the laws of physics and/or feasible construction. Nonetheless, they remain an excellent source of ideas and information. The good folks at www.thedump.scoutscan.com have made Thurman’s books available for free download.

  • Fun with Ropes and Spars (1956)

  • Pioneering Principles (1962)

  • Pioneering Projects (1961)

  • Progressive Pioneering (1964)

• Pioneering Merit Badge Pamphlet (Boy Scouts of America, Multiple editions)

The current edition of this book is available at most Scout shops but is not recommended. Earlier revisions are much better. If you want to buy a book about pioneering, find a used copy of an earlier revision or buy a copy of Scout Pioneering (John Sweet, 1974) from Scouts Canada.

• • The current revision (2006-present) of the pamphlet is not very good, containing numerous errors, and replacing much of the useful content from older editions with flashy, but not terribly informative, graphics. Don’t bother building the rope making machine shown in this edition. It is too lightly built to work reliably.

  • The 1993 revision of the pamphlet, written by Adolph Peschke, contains a large section of useful knots, recommended gear for a troop pioneering kit, a color coding system for ropes and spars, and building instructions for many small to medium size bridges and a simple tower. Don’t bother building the rope making machine shown in this edition. It is too lightly built to work reliably.

  • The 1967 revision (and identical 1974 edition) of the pamphlet contains information about the construction of large bridges and towers and permanent bridges that do not appear in subsequent editions. Much of the material from this revision is reprinted in the 1967 edition of the Scout Fieldbook.

  • The 1942 revision of the pamphlet by Walter H. McIlroy contains information about the permanent construction of bridges, towers, rafts, and trails, working with block and tackles, the long splice, and careers (circa 1940) in engineering and related fields.

• Scout Pioneering by John Sweet (1974)|

Sweet was a colleague of John Thurman. The first half of his book focuses on skills and principles, and the second half gives instructions for building specific projects. Sweet’s book contains fewer projects than Thurman’s books, but they are all buildable and are more comprehensively presented. It is still in print and available inexpensively from Scouts Canada at https://www.scoutshop.ca/.

Hard to Find Books

The following books are all out of print and difficult to find, but well worth reading if you run across them.

• A Manual of Elementary Seamanship, 8th ed. (Capt. D.Wilson Barker, 1919).

• A textbook for Junior Officers written at the end of the era of merchant sailing ships. Includes extensive information on knots, splices, and rigging; most notably including illustrated instructions to remove and re-step the masts of a square-rigged sailing ship using only equipment carried onboard and a clever method of calculating the loads on the component parts of a derrick from a sketch without the use of formulas or complex math.

• FM 5-10 Engineer Field Manual: Communications, Construction, and Utilities (War Department, 1940)

• Extensive information about assembling pontoon bridges and floating them into place, launching prefabricated bridges across a gap with a launching beam, calculating the capacity of truss bridges, building timber trestle bridges, rigging generally, and much more.

• FM 21-105 Basic Field Manual, Engineer Soldier’s Handbook (War Department, 1943)

• An updated and abbreviated (1/3 the length) version of FM 5-10. Contains information on bridging, rigging, anchorages, and the proper use of woods tools.

• Instructions for United States Coast Guard Stations 1934 (US Treasury Dept., Coast Guard, 1934)

• Contains illustrated instructions showing how to rig and use a breeches buoy to remove the crew and passengers of a grounded ship. This would make a fun activity at a camporee or summer camp.

• TM 5-225 Rigging and Engineer Hand Tools (War Department, 1942)

• A precursor to FM5-125. It assumes that the soldier will have limited access to power sources and power equipment compared to the later manual. Its second half lists the hand tools contained in common military toolkits of the day and provides brief instruction on their proper use.

• Useful Knots and How to Tie Them (Plymouth Cordage Company, 1946)

• A short pamphlet of basic knots and splices. Contains an excellent explanation of the relative strength of knots and splices, including high-speed photography of a knotted rope breaking under tension.
