Over in the HOMEMADE TOOLS AND JIGS ETC. I have been putting together a Bulk Brass Order (http://www.woodworkforums.com/showthread.php?t=75033). We are intending on getting a single sheet of 260 Brass Alloy, for making infill style planes to share amongst each other.
We however need the sheet cut up into strips to share amongst members.
The question is how we cut it up?
George White says will guillotine it for us for about $60 - $80 for the 1800 x 900 mm sheet. However the sales guy says that the guillotine will cause the brass strips to warp and twist into banana shapes so much that the brass will roll around. Now is this an exaggeration, or fact? If guillotining the brass will cause it to warp and twist, how much will the brass strips warp and twist by?
The other option I am looking at is water jet cutting, since laser is out? I sent away for a some quotes and the first quote back was insanely expensive, he wanted $20 per cut and $50 programming. Is this a reasonable price to pay for cutting brass via water jet?
Another question is about laser cutting, I am told that laser cutter will not cut brass because the brass it so reflective and the laser reflects back into itself and gets burned out. However, just theoretically speaking could you coat the brass in non reflective finish and then cut it?
If anyone has a suggestion as how best to cut the brass plate up and who could do it, it would be much appreciated.
*EDIT* The brass is located in Melbourne.
