I can either buy a new 4ft slip roll (Cant afford it and all the ones I can find locally to me here in Maryland are in less than usable shape...) or I can make one...
McMaster has the gears and bearing I would need. The sides I can have machined out of something substantial at several places.
But the rollers... I need to figure that one out, I am doubtful that 2" OD Iron Pipe is substantial for even 0.025" (ish) stainless sheet...
Suggestions?

My first question would be, do you really need a slip roll or could you do with a cheap ass replacement that has worked fine for me over the years? It is just as it looks two steel pipes drilled through at each end, two long bolts holds them together and the gap can be adjusted with a nut. After some practice there is not much you cannot do on this type of roller, I´ve rolled all my pulsejet engines on it and have found that it actually is easier to roll cones this way if you haven´t got a friend who can do the cranking. Cheers!

I had not thought about using two rollers as a stationary english wheel...
What are the two pipes you have there, regular steel?

I build this about 2 weeks ago for my big engine. No need for bearings or gears and works pretty well If you want I can give your the sketchup model. I got some materials from the scrapyard which I though I could use and I designed this thing with those materials in mind. You can alter as much as you want as long as the main mechanism stays the same
