Hello. My name is john yeoman, and I live in York U.K. I was wondering if some one could answer 3 questions for me about my Tom Senior M1, please. What is the thread in the oil hole on the Main Shaft? There is an oil hole on top , at the front of the saddle. What is it for. Can you adjust the end float on the counter shaft? Thanks.

Welcome, John, there are lots of experts on M1 mills here, I cannot help, unless you want to know about light verticals. TS uses mostly BSF and Whitworth threads.

Hi John,

Can't help with 1 or 2 until tomorrow, but for 3 – yes, you should be able to. Just doing a countershaft rebuild at the moment, and the grub screw holding the double pulley on to the shaft on the inside should bear down onto a slot in the shaft. So loosen this screw and tap the pulley to give the required clearance.

Regards, Chris

Here's a link to the Denford Forum. Loads of interesting stuff, including manuals and drawings for Tom Senior machines. **LINK**

I'll leave you to find your way to the Tom Senior stuff – finding it will likely involve numerous interesting distractions…

Hi John,

I can't see any holes in the main shaft, but there is a ball oiler on the back gear and also a grub screw on the main shaft pulley. This grub screw is 5/16 BSW.

Neither of the machines here have oil holes on on the front of the saddle other than ball oilers for the slides. There is a 1/4 BSW hole tucked away to the right hand end of the table stop tee slot, but not sure whether that is for oiling.

Regards, Chris
