3rd video & cutting holes
Hi Tony
Third video is great, and concerning your earlier post on cutting holes. One of the tricks I use for cutting holes 1/4 to 3/4 in canvas, webbing, gasket material, paper, leather is by making up spin punches of various sizes. These are made from thin tubing any thing that can be fitted into the chuck of the drill press or hand drill. Just sharpen the cutting edge with a file by spinning the tube in the drill and lightly holding the file against the tube at an angle.
Then you can cut holes in almost any soft material by laying in on a soft piece of wood and lightly pushing the spinning punch against the material. I've found that the drill press works best, particularly if set at a higher speed, cuts a nice clean hole. Every now and then you have to stop and clean out the hole cuts in the tube.
I've even used rifle cartridges not as many cuts without re-sharpening as steel tubing. But with lots of old spent .44 and .303 casings around to use up why not, the spinning cartridge casing in the drill cuts a much neater hole then firing the bullet through the material.
Cheers Phil
