So hey, all you that have done this... would you not suggest doing it if you're a heaver rider? I'm in the mid 220's down from 260 at the beginning of June, and still going (so don't laugh) but I don't think that I'd be doing myself any favors trying to get down below 175. That said, if I can find a good deal on a B-17, I buy one and try this, but not if I'll break it.
BTW - to the OP'er, nice cracks about the burning dead cow smell and opining that a specific tool made to vut leather well might be called a leather cutter.
