Hey need input I am setting up a build night for my sons troop at home depot and we have 40 boys. is 2 band saws and a jig saw enough power tools or should I ask for more? I plan on having a few dremel tools also. any input would be helpful
I would highly recommend that you use 4 of the Ryobi scroll saws with the 7TPI blades. The older boys(Wolf+) can saw their own bodies with these. If needed use the "Hand over Hand" method where the adult stands behind the cub and helps control the wood. WARNING-- Adults will push too hard, the kids will let the saw do the work, result is that I have NEVER given a band-aid to a youth but I give 1 or 2 a year to adults. Stress that they "push with the thumbs" on the back of the block. Tell them not to "push with their elbows" as that causes too much pressure.
I would also get one of the rotary vertical spindle sanders with one of the larger spindles. The small spindles can cause the boys to create a wavy surface.
I would use some of the Dremel tools for doing the axles. You need to use a smaller collet than it uses for the bits. A small metal file can be used to take the burs off the underside of the nail head. Follow that up with 600 grit and then 1500 grit polishing for about 6 seconds each. Warning: Too much sanding will result in thinner, slower, and wobbly wheels.
Some sandpaper(80, 150, and 220 grit) can be used by the kids to achieve the smoothness they desire. I made sanding tables from 1x3's on edge with 1x2's on edge on the inside to support a piece of peg board. I reinforce the pegboard with two 1x2s evenly spaced.
The Dremel tools can be used for sanding by the kids. Just remind them that the lower speeds are what is needed.
We also explain how to use graphite and do a rail rider alignment with a 4" in 4ft curve.
