Tell me about these kit cutters:
Well, I can't speak to laser cutting kits because I've never done one, but it seems to me that an airplane that is cad designed and transfered straight to the cutting equipment will be far more accurate than one that's hand drawn on a plan, and later copied, by whatever method, into the computer.
Having said that, I'm not so sure that copying a design from a hand drawn plan is any more accurate than just simply making templates and cutting it by hand.
True, you can correct for symmetry, and round holes that aren't, etc., but all the cumulative errors are still there, as well as the inaccuracies you add by the copying process.
I agree that the prime advantage for laser cutting a design is to accommodate the cutter as a labor saving tool.
I fail to see any other advantage.
