It's been awhile since I wrote, I've been having a spot of health problems, a lung infection, three days "observation" in hospital the week before last, antibiotics, I'm tired, but on the mend, more scans next week. trouble sleeping, but that's not new!

Isn't the correct tapping drill for 6 mm in steel 5.2 mm ?

Dave, 5mm is the general used size. I have come to the conclusion that my build up material was work hardening, the deeper I drilled, the harder it got as despite frequent oiling it was getting hotter and hotter in there!
Discretion being the better pat of valour, I decided that it would be easier to cross drill the dial and put a slug of Teflon in the hole with a grub screw to put pressure on it to give adjustable friction on the dial.
The white lump is a Teflon off cut, I put it in the three jaw on the little Emco, turned it down, I had to finish it by hand as it was too soft to go all the way down to 5mm.
Reassembled. The previous owner had treated the oil nipples as grease nipples, cleaned and oiled up it's a lot less stiff. The "pear" handles bent back very easily with a piece of 30mm pipe.
I tried to clean up the threading dial, now it's illegible because the engraving is really shallow, when it's turning you just can't see anything, not even the lines!
AdeV, did the seller of the other Edwick ever get back to you, good thinking on your part. Each time I go to look at something, you've been there before! Like you, I didn't know any thing about the oilers, other than they are not grease nipples (grease zerks), I was able to benefit from your experience once again, I've ordered a pump type oil can that I should be able to adapt as an oiler.
regards, Matthew.
AdeV:
Hi Matt,
The guy I bought my spare parts from has since scrapped the rest of the lathe, so no joy there.
The chap who's selling the early model that Andrew found, has promised to "try" to get a photo, apparently he's not near the lathe very often (I get the impression he's selling it on behalf of someone else).
I'll post here as soon as I have anything...
I must admit I've never investigated how my cross-slide gauge works, I just un-nip the outer wheel, adjust the inner, and nip up again. I always assumed it just trapped the inner wheel between two fixed elements...
mattinker:
AdeV,
I discovered when I got the dial off mine, that there was a cross drilling with a wedge shaped piece in it. A grub screw in the shaft pushes the wedge out to give more friction, it's not just pinched!
Regards Matthew.

I always thought with metric threads you deducted the pitch from the dia to give the tapping size , that's what I do it works and is easy to work out with my single Brian cell
