I have no affiliation with this, other than that I have some interest in it for cutting roofing, windows and doors. It looks like it will be funded in the first day, 93% funded in 23 hours as I write this. It is small, and not very powerful, but it will cut up to .8mm (1/32") plywood, which would work for cutting layers to assemble windows and doors. Also, for me, it would be nice to cut shingles from paper. I would love to hear from people that know more than I...which should be easy, since I know almost nothing about these things.
