:scratch: just use the tail stock centre and centre drill each end of the work ! it cant come loose or out with a centre holding the un-chucked end . :thumbup: Rob |

I was thinking of facing both ends, centre drilling and then centre on the mill and doing any boring in there....ah, but there's a spigot to machine. That can be machined in the lathe with tailstock support.... So thats my plan, unless anyone has any better ideas/suggestions? Oooops, just read John's previous post re faceplate mounting....yup that was summat else to consider...thanks for the idea. :thumbup: That sounds like a better way and cheaper than having to buy another chuck/backplate... |
| RobWilson:
Why would a 626 mill require a bored out riser, is that not just creating un-necessary work :scratch: Rob |

Thick walled tube is better than solid any day of the week, Young's modulus and at only 6" diameter it helps to have all the stiffness you can get when you are sticking it another 6" into fresh air. |
