Chipmaster question

I posted this on the Yahoo user group, but no response as yet.

Can anyone define the crossfeed screw for me in terms of diameter, thread form, pitch, hand and length?

The lathe is Imperial.

I want to replace the screw soon but cannot strip the lathe at the moment.

Thanks in advance,

Charles

I found a post that says the cross slide screw is a ACME 3/4-5TPI on a Student.

Charles,

I can tel you that it's left hand twin start. If you are going to replace the screw you would be advised to change the nut as well. You can get these parts from 600 group but may find Robert Pringle based in Harlow are cheaper but still prepared for a shock.

I ALL having trouble with my Colchester chipmaster clutch is slipping but I don't think it is the clutch there is a lot end play in the shaft it self and the clutch housing .and there is no information in the manual that I bought from tony Griffiths or in manual that came with it .so is there anybody out with the information that can help me there must be some worn parts or bearing I thought it was the variator but I have changed the oil in variator . thanks in advanced for any information regard nome

Charles, have looked at the manual and can only advise part numbers, but there is a choice of Eng or Met and std or anti-backlash nuts.
The manual is available on Yahoo Groups Colchester Lathes group.

thankyou I will have a look on yahoo regard norm

No look on Yahoo page seems to be out off use .I have tow manual but no technical information I look on ebay and the manual look the same has so back you hope you can help me regards norm

I think the chipmaster is the same as the Bantam, 9/16" diameter 10tpi pitch .200" lead left hand 2 start. I could possibly be able to knock out an EN8DM threaded blank to splice into your screw but I'm really busy right now. They are expensive because of the integral gear which I could also probably hob but if it is the sliding spline type, I have no cutter for the spline.
