Hello all.
Nearly completed this grinder. Please watch . This gentleman takes you through his grinder and how it works. If you read the comments you see I asked a question to get a scale of things. Mine differs that I used cheap cnc rails and aluminum extrusion and all in all its quite rigid. The motor I have used is a cheap 550 Chinese watt brush less sewing machine motor which speed control is done via foot pedal.I have done away with the foot control and used a pivoting bolt on top of the controller. You just screw it down and up goes the speed. I did it that way as I am electronically challenged .I can move the tail stock frame for different sized shafts to help with rigidity and a floating tail stock if I find alignment slightly out. I'll make a video of it in operation when I make a couple more clamps and make sure it is calibrated 4 x master cam to shaft.
Cheers
John
