as far as an answer to part b. of your question -- one guy swears by just using loctite to mount pulleys to shafts. Its on a thread around here someplace....
I see his point too, if its already a fairly snug fit, loctite could make for a pretty solid bond that's easily reposition-able with a little heat if need be.
everything else, i'm still learning. I personally just plan on finding a cold-rolled shaft at Home Depot/Lowe's and rolling it on the floor to make sure its fairly true, then taking my new prized possession home with me. |
