I don't want to sidetrack this post any more than is possible, but just to comment on Darren's leadscrew.

As you said, that is worn beyond repair. You can buy leadscrews fairly easily of this size, but from the US. If you bought say an 24" length, it would most probably do both cross and topslide. The taps for the nuts you could buy from Tracy tools.

I checked my acme taps, and they are 1/2", both left and right, so no use to you.

Screwcutting one is no problem, plus you would also make your own tap the same way. My machine is metric, so I don't know how accurate it would cut an imperial thread, I haven't got that far with it yet, otherwise I would have knocked one up for you.

Darren:
Thanks John,

I think this may be worth pursuing, esp as it won't cost the earth.

I did find these, though they don't list the 3/8 size they should be able to help. The nuts look just right as well.

Darren,

I would send them an email, but don't worry if they don't reply. These engineering people usually have rather large minimum order prices, but on the off chance, by reading the text, it looks like they carry stock and just might have an offcut in your size.

The other way is to see if one of our colonial cousins will purchase and send you a piece. It seems to be very cheap in the US (as is almost everything). The exchange rate isn't in our favour at the moment, but it just might be a much cheaper and easier option.

John
