Hi, all.
Hi, all. This looks like a good forum to be on, lots of knowledgeable people with good advice.
Speaking of which (probably bad manners to ask questions on my first post, but I'm in a bit of a bind here), I was wondering if anyone could tell me if there are any issues with removing the apron on a Macson lathe similar to the one in this post: https://metalworkforums.com/f300/t20...t=macson+lathe
During a moment of inattentiveness, the operator failed to disengage the facing feed and the carriage hit the mount for the handwheel. The autofeed no longer works in either transverse or longitudinal travel. My main problem right now, though, is getting the apron off so the damage can be assessed. So, any hidden traps that I should be looking for?

That link didn't seem to work for me unfortunately but I had an older flat bed macson and had the apron off it a few times.
1. Get the leadscrew/feed rod bracket off the tailstock end of the bed. On mine there were some tapered pins that were threaded on the and and you had to righten nuts to back them out.
2. Disengage the half nuts, disconnect the leadscrew and feed rod from the feeds gearbox on the headstock end. The leadscrew is just held in its socket by a tapered pin, the feed rod is held into a feed overload clutch again with a tapered pin I think.
3. Pull leadscrew and feed rod out the RHS of the apron. This should leave the apron hanging in air with nothing running through it
4. Chock the underneath of the apron up with wood blocks. Be careful to support it in a way you can lower it easily. Mine probably weighed 65kg or more.
5. Undo bolts holding apron to carriage
6. Lower apron, done.
For me the thing that happened most often was the overload clutch didn't slip easily enough so if you fed it into its end stop it would twist the push pull lever that changed between sliding feed and surfacing. I had to remake that more than once before I lightened up the preload on the feed clutch.

Thanks very much for the comprehensive description, Caskwarrior.
If it's the same problem as you experienced, I might make up a couple of spares of the damaged part/parts. Just in case.
