Luxcut lathe spare parts?
Well the slippery slope didn't take long to appear.
I'm able to obtain a DSL 1340GH lathe close to home and well priced. The automatic feed shaft is missing and the current owner says it has been like that since he owned it. Does anybody here know if the part would be available? Any ideas what may have been a reason to remove it in the first place, ie; possible damage or just choice (ex TAFE machine apparently)? Anything that may prevent it from being easily replaced if available.
Any comments on these machines from your own experience or here say is welcomed.

If i was to have a wild guess i would say they removed it so that students could not crash the saddle into the chuck by putting it in auto feed and walking off. But having said that, they could still do it using the screw cutting feature but maybe they did not make any threads so not likely.
The auto feed is a keyed shaft is it not?
You could have a go at making that.

A 1+ metre keyed shaft needs a big mill to make as well as pre machining stress relief. Not trivial at all. Plus who knows what else is missing from the feed drive. Betcha the saddle worm is gone.

Hard to say why it would be removed.
I wouldn't think for safety as using the leadscrew for feeding could create an even greater opportunity for crashes.
It could of been removed to replace a sheer pin on the shaft, there may of been a problem in the quick change with the feed leadscrew selector,they may of had a problem with the saddle feed engagement,they may of sheered the drive key for the feed,something may of got caught on the feedshaft and bent it causing the saddle to jam if sliding feed was used, hard to say.
If a new one was to be made I would use a piece of ground 4140 , a large mill table would be easiest but with care it can be done by moving the shaft along on a smaller table.
You may be able to get a replacement from H&F from a newer machine but cost may be high.

If you took care it could be done quite nicely on a shaper. Done in several passes it could produce better results than on a mill.
Edit: even on a mill, you could do it in several passes. Rig up an indexer that locates in the keyway so it keeps the correct orientation each time its moved along for the nexf cut.
I would have a go. I cant comments on what other parts are ir might be missing, thats another issue...

Can you explain how you would do this on a shaper ?

Well thanks all for your contributions.
As an ex TAFE machine, I did think it may have just been a deliberate crash avoidance removal, but of course there are other possible reasons, as discussed. Without inspection and some idea of what should be there it's hard to say what else is missing or possibly damaged. Of course automatic feed isn't essential but certainly should be there. I'm not sure I want to go and purchase half a tonne of lathe but it is a pretty good price (I think).

Just bear in mind this is a slippery slope. When you inspect do so very carefully. Sell your other lathe before you get another project.

Maybe a bit fiddly but with a larger shaper going from each end I can't see why you couldn't do it in two goes.

The keyway would be at least a metre long and its maybe a 1" shaft. Doing that on a 500+mm stroke shaper would be like threading a needle with a bus.

I see that it was suggested that the shaft may have been removed for safety reasons , this seems to me to be a strange thought,is this a sort of common practice at TAFE these days ,if so how would a student gain the skills required to use a machine tool properly.

Hi Guys,
I think that I would try and find a parts illustration for the lathe ! At least you would then know what bits went where and if any were missing. It is very suspicious that a part is missing without any explanation as to why...Best Regards:

I'm not sure that feed disabling is common on TAFE machines and this probably isn't what is being suggested. It is just a possible explanation of the shaft being missing. On old Hercus lathes the change wheels were often left off school machines to prevent carriage chuck collisions. Even manual feeding the kids would still manage to do it. As pointed out, this lathe still has lead screw capability.
