Built this for Pack 477 to use on there warm weather camp outs. It makes a great water balloon tosser. There are a few tweaks left to maximize the range. I need adjust the release pin angle and sling length along with the weight.
A few stats:
Weight (with empty weight box) 105 Lbs.
Swing arm 95 inches long. 4.5 to 1 ratio.
Length 72 inches, width 46 inches.
Maximum design swing weight 100 lbs.
I want to say there was 20 to 30 hours of design and drawing, at least 60 hours of build time. Every piece was run through the thickness planer and table saw to make 2×4 into 1-1/4×3. Help make the layout for final cuts a little easier. I would say I had 50 or 60 gallons of paced shavings. I plan on building a falling arm version this summer. I doubt I will run all those pieces through the planer.
All in all it was fun, but next time I will leave the 2x’ as is were I can. I think it would be pretty easy to make this 1/2 the size out of 1 x and have pretty much the same results with water balloons.
Try one you will like it.
