A thought - would, leaving the plate in the bottom of the domestic oven on a wire tray for a few weeks so periodically, as the oven was used for cooking, it was heated and then cooled slowly, relieve the strain in it?

Probably but its got assorted oils and paint on it and since its scrap anyway I can live without incurring SWMBO's wrath. and cleaning the oven is my job :-(

I thought that traditionally they were left outside the workshop, and the apprentices were instructed to pee on them when the need arose.

Bit late for that :-)
Castings? I could undestand pressings.
Tooling some but jigs yes.
If they were to resurrect the original design the jigs wouldn't be needed. Instead of making say a headstock the old way with a reference plane and 12 or 15 jigs setup in stages on probably 3 machines the modern way would be to get a 4 axis CNC to grab it and machine everything in one go, no jigs needed and no intermediate inspection stages. probably far more accurate to boot.
No body seemed interested in the tooling. I bought all the taps for the feeds screws for the whole range, imperial and metric, for peanuts. Plus a lot more stuff like gear cutters etc.

Where did you hear that?
Not hearsay, I was down there Monday and Tuesday buying all the good bits , all the jigs were being dropped into skips supplied by Simms at Lenton and going straight to their yard and hence the fraggie machine. Don't bother going to Simms, you won't get in the yard and by tomorrow all the jig store will be empty if not already so the speed they were working.
Some tooling is still there but it's all over the place, anyone interested has to go down and first of all speak to Mark at the asset preservation company then he'll direct you to one of the few remaining Myford employee's who are still on the payroll for just this purpose.

Sorry, I thought I was quoting from your contribution to the appropriate discussion thread on the Model Engineer magazine web site (or was it David Clarke?)
See my reply of a few seconds ago to JS
Given that you've already been there, I doubt that there's anything left worth nicking, let alone buying :-)

FWIW I re-mounted the faceplate today. I have 0.001" runout at the rim and
0.0035" convexity across a radius. As I suggested earlier, a piece of utter crap. ttfn Roland
Difficult to fit a lathe into the old poacher's pocket though ;-)
