Then two 1/8" roll pins. How much does that cost? Well the brass or bronze is the relatively spendy stuff but then again a machine shop will have some shorts lying around for a good price. Maybe 5 - 10 bucks for that. The stainless would be a couple of bucks. > > I'm really spit balling the material cost.

But then when I make something, and it's all custom work, and if I actually cost out my time, then the price of things doesn't seem that bad. > > Alistair > >> On Jul 24, 2016, at 11:52 AM, David McNeely <davmcneely40@gmail.com> wrote: >> >> Alistair, this is an elegant and seemingly very good redesign.
