Metric Myford super 7

[john fletcher 1Participant @johnfletcher1]

I bought two gears from John S, 33 & 34 to enable me to cut metric threads. I am at a loss, as to where they fit in the gear train system. A diagram or sketch would be appreciated, or can some one point me in the right direction where a picture or photo of the set up, is to be found. John

Cutting Metric threads

[Simon Williams 3Participant @simonwilliams3]

Hello John, plenty of info on the forum which provides instructions and piccy's of the set up you are looking for. Here's one such, there are others.

I'm assuming you have the Mk2 quick change gearbox fitted – the 33 and 34 T gears are specifically for use with the gearbox, not as part of the simple gear train. You also need to decide if you have the old Mk1 gearbox or the much more common MK2 gearbox. If you can post a picture of the right hand face od the gearbox (nearest the chuck) we can confirm which you are looking at.

If you want chapter and verse, Brian Wood's book "Gearing of Lathes for Screwcutting" is worth having. Available from ArcEuro also Amazon.

Hope this helps Best rgds Simon

(Neil – I thought I'd sussed out embedding a link, obviously not! Please edit if you think it simplifies things. Thanks)

EDIT – Ah Hah!  I didn't expect the "link" just to appear like that when it compiled. Sussed it at last!

Edit 2 – Have I read somewhere you've got an S7 with a METRIC leadscrew?
