All disc bolts out, bearings shouted at, removed then thrown in bin, so wheels ready to be taken to be powder-coated.

But that last remaining header bolt...

That welded-in allen socket snapped as soon as a ratchet looked at it...

A little more access required, so the headers were cut off. A shame as they were actually rust-free but fuck it...

Another way is to heat stud till red-hot then cool down with engine oil (very smokey) :D and best done outside, but the heat draws the oil down the threads and makes it loose, its an old blacksmith trick (y)

Now on my fifth nut welded onto the end of the stud... this is partly (ie, entirely) due to my crap welding technique and not getting the weld in the nut, which only sits on a single thread of the stud, right down the nut and onto the stud... but, each time it does get the stud out by about an eighth of a turn before the weld breaks and the nut snaps off... softly-softly, catchee monkey.

I have seen where a penny washer was placed over the remains of the stud and welded to the stud as it allowed better access to weld,and then a nut welded to the washer might this help you ?

The only problem with that Daz, as good an idea as it is, there's not room for a penny washer as it's the inner stud of cylinder 1, only just enough room to get a socket on a 13mm nut ;-)

How many more 1/8 turns will it take to be able to get the mole grips on it?

About 40... (1mm per full turn, 5mm protrusion required for the moleys...) 

But...

 

 

 

... it has now snapped flush with the surface of the head. Arse.

In other news, repainted bottom yoke is back in with refreshed bearings, swinging arm is out (more awkward fasteners) to be repainted and given new bearings. Ignition switch on bench awaiting surgery (switch cut off, wires reconnected to make live with resister in wherever it needs to be, maybe an on/off switch added too, depends on what guidance I get from the wizards as to how to deal with the magic smoke).

RH rearset modified so that brake master cyl fits properly. Bracketry removed from subframe that is allowed to be removed.
