I needed a custom bumper the other day so I tried something and it worked quite well so I thought I would share. I mounted a house cue bumper on a mandrel and ground it to shape using a stone and the router.

Did you use a lubricant when grinding it??
 
Thank you for freely sharing such. If I may make a few suggestions:
Try to stick that grinder shaft into the collet some more. Cut the shank if you can't slide it in any. Unlike HSS or cardide bits that we normally use with the high speed routers, grinding stones can wear in chunks and this will cause tool imbalance. A few more hits of an imbalanced stone on a workpiece can cause that stone to shatter and flying all over the place. Hopefully nothing gets in contact with you. High speed and bits that easily get imbalanced don't work well together.

Nope cut it dry, I just turned the lathe slowly in opposite rotation as the stone. Using coolant would have bin advantageous.

Thanks for the suggestions Edwin, If I modify any more I will definitely take this into consideration. This was just a quick idea which I wanted to try so I through the stone in the router and proofed the idea. I did however slow the router down with a speed controller.

That's a good suggestion...I didn't think about that yesterday when I was first reading this...hate to think what would happen if that did fly apart...you'd be pulling chunks out of the walls and ceiling, hopefully not out of your hide :eek: , for a week....

Hi Kevin. In case like me you missed them at first, look closer at the picture. There is a before and after bumper in the picture.

My mistake, I was so focused on the tooling that I had overlooked the bumpers.
 
Jeez....I was looking at those and thinking they were bolt heads....:rolleyes:
