| A quick trick I forgot to mention in the tailstock thread. |
| (1/3) > >> |
| websterz:
I have a 4 jaw chuck but it is a PITA to set it up just to turn 1 little part like the cam for my tailstock lock. I have my 4" 3 jaw on the lathe and it is running right at .001 TIR so I hate to mess with it! :) You may or may not know that you can offset parts in a 3 jaw chuck by using a spacer against 1 jaw. I put the cam blank in the chuck with a flat washer laying between it and one jaw. When I tightened it down I used a marker to make a small witness mark so I could relocate the part in the chuck if I needed to. I did, in fact, remove and rechuck 3 times before I got the cut like I wanted it. Start off slowly as it is an interrupted cut, but with a sharp parting blade you can cut a very servicible cam. If it's not offset quite enough use a thicker washer, I don't recommend using more than one for safety reasons. Also stand to the side, out of the flight path just in case the washer takes to the air. :bugeye: |

I've often wondered about trying that, so it works then you say... :thumbup: |
| sbwhart:
Yes it does work Darren I've used a number of times to make excentrics :thumbup: but as W says you can't over do it or bits will fly. :zap: Stew |

You guys calling me "W"...that's what we called George W. Bush. Not sure it's very flattering. :doh: Please take that in the intended lighthearted manner in which it is intended. Just call me webby or webs...everyone does. :thumbup: :beer: |
| sbwhart:
OK Webby it is :thumbup: Thanks for the chuck tip :thumbup: Stew |
