Art?
Go to Yahoo groups and look for "Brasscollectors". Great bunch of folks. I'm sure someone there can help you. Btw I'll look through my files and see if I can locate the tutorial that I found that actually shows a simple and effective way of building a universal joint. It looks and functions just like the ones that PFM (United) used on all their shays. The best part is you only need simple hand tools ( I'm sure you already have) I'll see if I can locate it for you .
