Since you where so close a couple of times, within a few thousandths did you ever let it run and see how long it would go even if it wasn't perfect? It is still a beautiful piece of work, thanks for...

I actually have one of the HF laminate routers, but dont know where to get a 1/8 collet for it. I agree its quite nice for the price. I use a lot of 1/8 pcb drills so need the 1/8 size

Hi,
Can you put a 1/8 bit in and check for runout during rotation? The collets in a dremel are bad for runout, would hope the rotozip would be better. Also how easy was it to mount the unit? a...

I would hook them to the center tap and one end. Unless they are very low inductance you should get better performance. I also believe that if you hook across both coils. you need to cut the current...

I got my 6 G251's and am planning on using 3 of them on some steppers I picked up cheap at the swapmeet. They are Sanyo Denki's 2A 103H7126-0415. I cant find a exact match but believe they are about...
