Thread: Straightening lead screw

Are you looking for someone on here to do it for you,

No.. I will get it done by one of the shops in Penrith near where I live.
Thanks, if you were offering.

Glad to hear that you sorted it to your satisfaction. Which method did you use in the end, tweeking in lathe with a special purpose collet, press and V block, or some other carefully concealed trick?

I don't have a set of V blocks, and my lathe surrounds are very restrictive, so, as Frank says... I did it my way.

I have a very large surface plate, 2400 450mm.... being my old but beautifully accurate jointer. I placed screw on the plate and rolled it about. Bending back to shape was done by the use of 1" ID water pipe, securely clamped to heavy bench. As I mentioned previously, I got it to within .003" which seems to be quite good enough. It took a while, but I didn't want to rush it and make it worse.

The resilience of human nature, the will to rebuild and the pragmatic and methodical germanic mind set supported by a massive rebuilding/reviatilisation process supported by the US economy.
As much as I don't like modern US foreign policy, there efforts post war in Japan and Germany were amazing.
