Finally fited table power feed,the adapter slides over the existing lead screw and is fastened with a pad bolt.
I fitted a ballrace as I had one spare and it saved turning a bush.

Still got the stop switch to fit.I'm trying to do everything without altering the original parts.The stop switch will probably be on a bracket fastened on the gib adjusting screws.

Adapter turned from 1" sq.

Thanks for posting the information, Alan!
This is a project that I'm planning on doing in the near future.
What does the allen bolt in the square section of the arbor do? Is it a set screw?
Is the motor a stepper motor? I've seen lot's of those for sale on Ebay and often wondered if they work in such an application.
Thanks and take care!!

Nice work Allen. What kind of mill is it and table size?

Reply to both Michaels....

The allen bolt in the square section tightens the brass pad bolt to grip the existing lead screw,better than a grub screw and doesn't mark the end of the lead screw.

The square section was drilled for the brass before boring for the lead screw,the brass was left with a small shoulder at one end and pulled tight with the allen bolt and then the lead screw hole was bored. Remove brass,cut shoulder off and cut in half at the high point of the arc bored,threads in one half only,bolt clearance in the other.

The unit is a bought table power feed.

The mill is a "Tom Senior" Light Vertical made in 1975,ex school machine,bought it off ebay,table is about 26"x 6",total traverse is approx 17"x 5"
