Greetings ya'll, new poster long time lurker here.
I have recently aquired a 6x12 surface grinder and I need to build some bushings that will be .500" id and vary in steps of 2 tenths per from .702-.706". I plan on using drill rod and boring the id on my lathe and rough turning the od. I have a small set of centers that I could modify into a fixture with some advice, or would a spin index be the answer? The bushings will be about 1.5" long.....and I can vary that by about .25" if need be.
Looking at the spin indexers I am unsure if the little grinder has the travel on the cross to allow it to fit. I would appreciate any advice or pics on how to attack this. Production speed is of no concern, these are for myself in my own shop. I will include a pic of the centers I purchased from a local retiring machinist. If anyone knows their original application......please share.
Lastly, I am green as spring grass to surface grinding aside from some automotive stuff. My machine uses 7x1/4" wheels, I know that much....I am not perfectly clear on wheel hardness and compositions. I understand grit, but appreciate advice on what wheels to stock up on.
Thanks for any help.
