I have recently bought a long cross slide gib strip and extra long thread, how do I go about replacing my old ML7 one, I will need to use the old handle/dials.

 

Many thanks for any advice.

Hi There

Don’t forget to drill the far side of the carriage to take the extended leadscrew.

Stirling,

To add detail to David’s post, If there is not a clearance hole for the new feedscrew at the back of the saddle, you will have to make one in line with the hole for the feedscrew nut. I had the same problem some time ago and phoned Myford for advice. Apparently, some ML7’s had this hole others not. the diameter of the required hole is 7/16″ (approx 10mm).

You have 3 options; 1) If you are happy to remove the saddle, you transfer the coordinates of the centre of the feedscrew nut hole to the back of the saddle, set it up on your milling/drillng machine and produce the hole. 2) If you are not happy to remove the saddle but you have access to the back of the lathe, you can mark out and then carefully drill the hole by hand. 3) If like me, the back is not accessible, I turned a long bush to be a snug push fit in the feedscrew hole, with an internal diameter to take the required drill. Using a variable speed electric hand drill and a long series 7/16″ drill I very carefully drilled through the rear of the saddle from the inside. Be aware that the edge of the hole comes very close to the top face of the saddle. After carefully cleaning, the advice from Myford is to fit the new cross slide without the feedscrew and nut and adjust the gib screws for best fit first. I hope this helps, it worked for me, and the long slide has proved extremely useful.

Regards,

Gordon.

One last point, wind the leadscrew right in, before you finally tighten the cap head screws that hold the leadscrew bracket to the front of the cross slide. This ensures that the leadscrew and the leadscrew nut are in the best alignment position.

Many thanks everyone, this is excellent advice.
