Hi everyone,I just picked up a good condition Celtic 14 lathe, made in Belgium by Mondiale. It's the older of the two styles I've seen, but haven't found a serial number yet to date it.
I got hold of a user manual in French, and am planning to translate it to figure out lubrication etc. In the meantime, though, I'm hoping someone here has used one of these lathes and can advise on the dials and controls on the headstock. It's a bit more complicated than my Lodge and Shipley.There are 2 dials on the headstock itself, marked A-B and C-DThere are 3 dials below the headstock, marked as follows:E-F-G-H1 through 9J-J-K-KThere's a 4 position dial below that, on the plinth castingI think that A-B and the 4 position dial control the spindle speed, BUT/ the forward / reverse lever on the apron also has 5 positions: fast for / slow for / off / slow rev / fast rev. Huh?The threading/feeds chart also has some weird headings, like 'BD'. What does that mean? B and D are on different dials. Also, there are Roman numerals in some of the row headers, but I see no Roman numerals anywhere else on the machine.
Help!Thanks in advance for ANY info on how to use this lathe!Best regards,LeeSent from my SM-N920T using Tapatalk. Ok, I have it figured out. Hopefully this can help someone who's equally clueless in the future.The Roman numerals refer to the change gear setup behind the outboard panel, as the lathe can be setup for screwcutting:I: metricII: imperialIII: modularIV: diametric pitchIt's currently setup for II: imperial, and metric just involves flipping the 36 and 127 tooth gears. I don't have the extra gears required for modular or diametric pitch threads, but I think I'll manage without:-)The J-J-K-K lever controls the leadscrew rotation. There are two 'J's' for forward and reverse, and same for the 'K's'. K is mostly used for imperial threading.I ran through the spindle speed range and a few random feeds/threading settings, and all seem to work fine. The shear pin was broken on the leadscrew, but that was an easy enough fix.

The pin that came out was a 0.057' square key. I replaced it with a small piece of shim stock cut to fit.The only other thing I've noticed is that the feed engagement lever on the apron gets consistently stuck in the 'on' position and needs a smack to disengage. Need to figure out a way to make that better. Otherwise I think this is going to be a nice lathe to work onLeeSent from my SM-N920T using Tapatalk. Hello Lee, On mine the ways aren't hardened I think, doesn't look like it.I only gave it a quick paintjob, cleaned up the essential parts.I measured the headstock hole, and it should be a MK5.I'll try to borrow a drill or somewhat from work to fit.But it says so in the manual and also on lathes uk.Is It possible for you to see what speeds the motor has?
And maybe the size or the motor pulley.I'll probably run it with the pulley I have, but maybe I can upgrade it when i know it is in working order.Thanks,Steven.
