Hi all:
Recently went to Colonial Williamsburg with the family and I think I had a better time than the kids. Anyway, in the joiners shop, they had a treadle lathe which the guys let me pedal on for a couple of minutes. Not to turn anything, just to check out the motion. I am hooked. Since then I have been looking around for plans etc so that I can build one for my shop. The wood working seems pretty straight forward - I am sure alot of tinkering will be called for with the pedal and the linkage.
My question relates to the non wood working portion of the machine - the bearings and the shaft - mechanics not being my strong suit. The plans I have seen (mine will be a combo of many different plans) call for a shaft (say 5/8 drill rod) to pass thru 2 bearings as well as / or terminate in/at a thrust bearing.
Questions:
Does the shaft go thru the thrust bearing like regular bearings or just end at and butt up against the thrust bearing?
Does the thrust bearing get secured to the shaft?
Other than stop collars on the shaft, is there another way to limit the shaft from running thru the regular bearings (assuming the thrust bearing does not lock onto the shaft)?
Is there a method of securing the bearing in the wood other than a press fit in a hole, or is a press fit good enuf?
Lastly (for now), what type of inboard end would be most preferable on the end of the shaft (threaded, smooth shaft, etc?) and is there a way to get a MT adapter on the end of the 5/8 shaft?
Where should I be looking for bearing and shaft supplies?
Thanx in advance for the help.
