Ok so I have this conundrum squeezing the last bit of accuracy on a BP V2XT cast Iron
and part of it is that the shafts on my servo motors are not long enough to go all the way through my pulleys. Set up is Ametric type taper lock bushings/collets.
basically what I did in pic is add a small insert and screwed it to servo shaft's tapper hole. We talking like .5" long stub. Now basically with my belts being say .3" out of align. I was wondering if there is a good idea to extend that shaft so the pulley will be fully supported. Right now as is it isn't and I need to move it about another .3" off the shaft. 1st idea came to mind is thread a shaft extension and then use a file to file it down under the servo's power so it is perfectly concentric with existing servo's shaft? Maybe a few spots with a tig and nickel rod? then grind it down. Tapped hole in shaft is 10-32. shaft also has 3/16" keyway but pulley collet doesn't have a mating slot. Any ideas or input?
