The width of the blade in the HF type bandsaw limits its use as a scroll saw, but I would like to cheat and put a much thinner (1/4 or 3/8) blade in for occasional uses where I really need to cut a tighter radius. The problem of course is that the flange positions the blade so the teeth would tear up the pulley and also cause trouble with the blade guides.
The first problem I propose to cure by grinding or resetting the teeth on the inside so that side is flat. This will reduce the kerf but there will still be some from the outside. The blade guide problem I would help by removing the outer blade roller and puting in a shorter roller or just a solid block, properly lubricated. Not the best solution, but I don't have enough use for tight radii to justify a special machine, I just want a kludge to work for rare occasions.
Any comments, I don't want to re-invent the wheel.
