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. jhnyeoman485@gmail.com

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…

Thanks to Chris and Anthony, for advice on my Tom Senior questions. John Yeoman. jhnyeoman485@gmail.com

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
