Re:
Bike all stripped down to a bare frame, and... it had to happen.
All was going well until I got to removing the chainset. I always start drive side crank first and in this case the cover bolt was a little stiff, so, that off a quick squirt of GT85 was applied inside and out and then the crank extractor tool was screwed in. Slack taken up I inevitably encountered some resistance, I applied pressure and gave the end of the crank tool a tap or two with a hammer, this was repeated a couple of times and seemed to be working, especially when there was that inevitable give and everything started to move.... well, by everything, I mean the threads from the inside of the crank. :facepalm:
I moved the frame in to the big solid bike stand and stared work on the non drive side, that came off as easy as you like so I started on the BB. A quick squirt of GT85 and then a little over 120ft lbs applied with my (Hewland Gearbox) torque wrench (note to self, buy a knuckle bar), and everything was on the move, at which point I realised I was dealing with one of the metal BB, plastic d/s cup type shimano bottom brackets, so, out came the big punch and mofo hammer. Success! d/s crank removed.
The rest was plain sailing and a quick rub down with white spirits has most of the cack removed.
So, a new BB is going to be needed, along with a new 1" threaded headset, because the factory fitted one probably cost the best part of 20p, so is serviceable, but mostly made of plastic. I have a choice of cranks, from Shimano SLX, through RaceFace to Middleburn.
Next job, is to polish and wax the whole frame and forks, and then we can start rebuilding.

Re:
Gave the frame and forks a good clean and a once over with the T Cut.
Tonight the rear wheel was cleaned; rim, spokes, hub, freewheel. I then pulled the bearings out as they were a little grumbly. Nothing to worry about, just old grease.
So, back wheel cleaned and Conti Contact II tyre fitted.
I also ordered a new headset, pedals, 7 speed cassette and chain. I am going to see what the original Gripshift shifters are like, but as a backup I have some Sachs Wavey shifters in reserve.
Tomorrow night it is the front wheel and hopefully a really good polish / wax of the frame. Take the old headset out and then sort out a different set of cranks / BB.

Re:
The d/s crank was a real shame as I really was hoping to use as many of the original parts as possible. That said, it weighs a ton (an old Imperial one, not one of your Johnny Foreigner metric Tonne's) compared to the SLX, so every cloud and all that.
I use some green gooey stuff called Bike Grease 2000 made by MOTOREX. I bought it some time ago and have used it for just about everything as it is water resistant and a lot nicer to use than the blue outboard motor grease I have used in the past.
