Hi Chris, What I normally do is face and turn the part, then part-off over length by .5mm or so. Face the parted end to a nice finish remove and measure the length, noting down the amount still to remove. Re-chuck with either end (depending on design). With the compound set parallel to the ways, the compound dial zeroed with the handle turning clockwise and the part spinning, touch the tool tip onto the end of the work using the saddle, very lightly. I use a magnifying glass to help to see just when it touches. Then just use the compound dial to advance in steps until the measured amount is removed. I just did it this way with three bits of steel taking no particular care and they're all within .02mm It's surprising how accurate you can get just touching on something by eye especially if you do it the same on both. Cheers, :beer: Steve |

Thanks for all the suggestions so far. I`ve just been googling like mad to find a post that i`m sure either Stew or John (Bogs) made regarding making a chuck backstop for the lathe?? I`m sure there is one out there! I expect Steves reply is the easiest. Just parting off near to length, measuring and then taking off what is needed. If anyone knows the link I`m after I`d be grateful. Thanks for all the suggestions |

FWIW - can I just say that I find madmodder search very strange at times - I searched, back stop, backstop and many other variations which got "hits" but never to that thread. That is the one I was looking for, thanks John. That being said, John-Som, interesting link as well , thank you both. Chris |
