Cowells / Perris Headstock Compatibiltiy

(1/3) > >>

Hi All,

I've had an older model cowells with the M14 x 1.5 Spindle for a few years. When I bought it there were marks on the ways close to the chuck. Probably hacksaw marks. I've always had it in my head to rebuild the lathe and replace the bed with cleaner ways.

I've been looking at a few options (mostly ebay) and I was wondering if the headstock off my lathe would fit on a Perris bed and is this a good idea at all or is the alignment specific to each headstock/bed assembly. Second option would be to spend a bit more and get a cleaner cowells to begin with.

Any help appreciated, Cheers, Henry

Jo:
Why? In what way does the horrible marks on the bed effect the way the lathe operates? They are probably just cosmetic ... If so you could fill them with JB weld or a clear epoxy and scrape them level.

The only reason to consider drastic changes is if the lathe ways are worn.

I'd be sceptical.  These lathes are fettled during assembly, so there's no guarantee that major parts can be exchanged between two similar Cowells, let alone a Cowells and a Perris.

I agree with Jo - you'd have to take quite a chunk out of the bed to disrupt the movement of the carriage.

Hi Jo, yeah that's a fair question. Can't say they affect functionality but they are fairly pronounced and not easy on the eye  :)

I'd like to get the machine into good shape mechanically and visually so was just thinking this might be a way to make the bed tidier. I was planning to rebuild the lathe soon as there a few other issues I need to tackle anyway.

Thanks, Thought it might be a long shot alright. Don't want to give myself an extra big project
