Lovely shiney blingy bits there. Very nice. Did they polish the fork lowers you?

Yes, although they farm it out to someone else. It's the first time I've had anything polished I usually do it myself but they've done a much better job than I could have. One of the fork lowers had some deep marks in which although they haven't come out fully are nowhere near as bad.

Lovely work from Philpotts there..

I agree, I was concerned about the depth of the corrosion but they reassured me, apparently in all the years they've been rechroming pitted forks they have only had a handful that were beyond repair.
The fork top nuts have come out really well, they were really chewed up and marked...look new now!

after a bit of a delay in things due to unforeseen circumstances,  I have got my cam and primary chains ,gaskets and seals sorted...I'm probably using the existing bearings as they seem OK...im just unsure about the chain tensioners. Should I just replace them as a matter of course?  The wheels and guide seem to be in OK condition but they are 47 years old??

They may look ok but the rubber bits will probably be hard and brittle so best to change them as you are there.
Im a Nurse, trust me, this won't hurt.....much !!!

Made a start tonight on reassembling the motor...got the crank,mainshaft and final drive assembled in the top case. It is probably going to be several months before it (hopefully) runs..i am using graphogen and engine oil as lubricants? It's a great feeling when parts start going back together!...so far anyway!  :)

Today I got most of the engine internals fitted into the crankcases, I'm now waiting for a few o rings to arrive before closing the cases up..what are your thoughts folks on the oil catch tray that directs oil onto the drive sprocket? ...I've read that it can be quite messy...Can it be left out?

Mines still there turned down to its minimum.
It does get oil on the back wheel but I can live with that as I do give the bike a bit of stick. In the 5 years and almost ten thousand miles I have never needed to adjust the chain  :)

Oil on the rear wheel is a good thing in my eyes it keeps the chrome nice
By the time the rear wheel is black the bike needs cleaning anyway.

I always fit the oil plate and cap off the oil outlet with a O'ring  ;)
