Servian Drill Press Update
Well, I've finally manged to complete the resto on an old Servian Drill Press I rescued from the deceased estate of an old sparkie. Was a complete rebuild and replacement of the old donk with a slightly used DC treadmill motor with PWM speed control. Many thanks to John B for his advice and help - have learned so much from he and others on this forum. When you get to be an old fart and can still learn things, makes it even more worthwhile - thanks to all who helped
Due to the Bat Flu Pandemic and constant lockdowns etc it took ages for supplies etc, Won't bore you with the details in this post other than to say I had to get the quill straightened by an engineering chap - it now has less than 0.0001 run out which will do me. Bearings were all updated with modern shielded ones and because the cast iron table had numerous apprentice holes, mate filled those as I have no way of properly handling cast iron welds. He did a brilliant job which took 2 days to cool down in the thermal heat blanket - just so it didn't 'ping'
The paint was the closest I could get to match the original - the new one is a special Haynes acrylic 2 pack mix which the paint bloke made up for me - min of 1 litre (only used a quarter of that - rest is set like a rock in the tin; dries in 1 minute with a brush so you cannot go back over any - believe it reacts with O2 for hardness and requires special spray application so I brushed instead - paint is chip free, hard as a proverbial witches......oil just wipes off.
Motor runs ever so smooth and can be reversed for left hand bits. The pot allows very slow speeds and doesn't lose torque at lower revs...because the shaft is MT I can use all my lathe MT stuff as well as the chuck. Tacho works both ways in positive display from the Hall Affect Sensor I mounted to the drive. Reverse is so handy as saves me trying to mount things up in the lathe if I have to remove broken studs or taps etc. I scored a set of LH bits which I can now use and deliberately chose a keyed chuck over and auto one - just me!
Weighs heaps as has a solid shaft with cast iron head, base and plate - at least several hundred KG's....so I mounted it on a moveable frame because I have limited space now and added a few grinders and drawers so I don't have to move far to sharpen bits etc. being an old fart, makes it easier to get at everything
Here's a few piccies of what she looks like now.... if you want any specifics or more details just ask....thanks again for all your help, it was greatly appreciated...Lee
ps...sorry about the delay John

Hi Lee,
What a wonderful job you have done on that Servian Drill press
I must admit that I thought that you had abandoned it, but I'm glad you have completed the project, I'm very impressed.
Thanks for the pictures.Best Regards:
Baron J.

Good job on the servian restoration barkersegg. I’ve just acquired a 3mt servian drill press from a shed clean out ,there a lot of parts missing but they are heavily made and well built machines.

Thanks bunyadust and others for your kind feedback - it's appreciated.
Yes I agree they are well made machines and with care will last generations. Considering they were mainly built during and prior WW2 it's amazing how they adapted their production with limited resources etc to achieve the quality we now see. I have a Chinese pedestal drill with all the laser bib and bobs, tilt table, step ladder and key less chuck.......I feel embarrassed just to locate the Servian near it but luckily the Chinese press is destined for newer pastures at the grandsons - but he wants the Servian instead.....haha
They are heavy units indeed and not being as fit and ferocious as I once was the Engine hoist took a thrashing lifting and moving it around while being worked on - hope you eat your weeties or have a gantry at your disposal - you'll need it
Good luck with your resto and if you need any help just yell out and I can certainly pass on what I learnt during mine....remember...lots of piccies for us certified tool tragics .....Lee

just picked up a bigger brother of this one, an SA-1 and agree they sure are heavy, fortunately the seller helped load and unloaded with a tractor, and ours didn't even have a motor! was watching it for a while as it was a fair way away but was close to something the wife wanted on the way home from the city so the planets aligned, aim to do something similar with the drive motor so wasnt a bid deal it never had a motor.

gone variable speed AC as i have 3 phase and have access to a danfoss xlt microdrive, fitted the drive pulley to the motor yesterday and sized up the belt i needed, just waiting on an A51 belt and were in business. in the meantime i nmade a front pulley cover as it didnt come with the original. also made up a stand with casters to move it around.
