Has anyone got an up-and-running J2 engine that I could acquire in order to avoid what I expect might be an open-chequebook adventure? Thanks.

Ouch, indeed! Commiserations, John.
P.S. But didn’t you tell me you had a brand new crank sitting on top of the piano?

Wow! I’ve heard of the Hive Mind but didn’t realise it included a Hive Memory…. Impressive archiving ! Yes I do have a steel crank but I’m conscious a) that installing it is unlikely to be a very ‘containable’ exercise b) that my block is M Type so not really correct (and I’m reluctant to dislodge / replace the head studs as they seem to work well) and c) that the funny cooling arrangement I mentioned in another post is hard to understand. Blanked off waterways on the inlet side of the block face. Again, this has worked fine so I don’t want to change it.
All in all, this engine has worked well as a piece but is it a good basis for a new and maybe expensive one? It may be better / cheaper / easier to find a good J2 engine, drop it in and sell all these bits (now dismantled). Of course the good J2 engine referred to is probably hidden under a pile of straw somewhere in a unicorn stable, but I thought I’d ask!

Thanks Sr537 but I can't see that. Is it on their website?

John, have you thought about replacing just the crank and rods using original parts? I have a spare original crank and matching rods which are very good and wouldn't need any work. You are welcome to have them.

Replacing the broken crank with the new one and using P-type con rods (someone might even give you a set) would seem like a very cost effective solution.

But adding P rods to an old bent wire crank increases the inertia weight on an already weak 90 year old crank. Many blocks have been written off through chancing an old crank. There is only one way to do it properly.
Ken Robinson has a newly built high spec engine sat on his bench at the moment and it will be offered for sale. However, do not expect it to be a cheap price, in fact take a glass of brandy to drink if enquiring but, it’s reflective of a top quality build, including large cam conversion

Rich,
I think Sam was suggesting using P Type rods on the new crank pictured above, not on a replacement original which would, in any event have 1 1/2” journals compared to the 1 5/8” ones of a P Type.

Perhaps a "bullet proof" Scotch would be better?

Broken Cranks also make very good table lamps. Nick.
