I tend to agree with Peter Cook 6.

It's surprising what a bit of lateral thinking with tools and orientation can achieve. Modifiying as you are may prove a challenge in the end and more effort than its worth.

You also need to work within the limits of the machine design. The fact that you can apparently fit a piece of work in the available space may prove detrimental to machine performance in the long term if it is stressing motors / bearings etc. We all occasionaly have to push limits, but usually for a one-off job. If you intend doing many larger peces of work regularly in the future I would seriously consider a bigger lathe. I know its ££££ , but this isn't always a cheap ' hobby ' I'm afraid.

I wonder how much of the cross slide gib is actually doing anything with that 20mm extension block? Not a good situation, I suspect.

As previous posts, some lateral thinking re tool selection/mounting would likely have been a better solution to that block.

As regards the feed screw, I expect it is a metric trapezoidal thread. Lengths are readily available on the ‘net. The current thread would be removed and a longer length grafted to the remaining feed screw part. That might need some lateral thinking to achieve such an alteration, of course.🙂 Alternatively, making a complete replacement feed screw is an option….

Philip, I think you will find that the thread is 10 x 1mm pitch with a lefthand thread.

The Little Machine Shop in the USA have them:

Feed Screw, Cross Slide Extended Travel

1 inch longer that is used with their extended travel kit.

If you can't single point thread it yourself you can find 10x1mm lefthand dies from china via ebay

good luck

If you do decide to go the modification route, this one is good – I did it to my lathe.

There are several different descriptions online.

As above, you can buy longer screws for the job, but I turned my own (on the same lathe before I modified it) – not difficult with a little care. I have also seen one with an extension pegged and brazed to the original.

You should be able to buy a length of threaded rod of the matching diameter and pitch and machine the end for the handle to turn it into a feed-screw. Most likely it is a trapezoidal thread (metric Acme, sort of.) Although some hobby lathes have used a standard 60 degree thread. May be left hand thread, depending on your lathe. Plenty of such threaded rod for sale on the net. Sometimes listed as leadscrew etc.
