Glad I'm not alone.

I have Michael Morgan's book on scraping and as you say it's much more

Sorry about pressing the button too early. Will try to remove!
Austin, you mentioned 2 gibs but failed to give us the clue to the
lathe.
Am I right in assuming that this is a Myford Super 7?
If it is, the classic question is- 'is the thing warped?

Without 'connolising', there is a lot, lot on recons. Even little me!

sorry, I didn't. Colchester Student Mk 1, 1960 vintage IIRC, so it's 6
years older than me.
