A spanner has been thrown into the works this afternoon. Not a very big one, hopefully, but frustrating, and for a while a bit worrying. Got a call this afternoon from Brian at RN. They'd decided - very presciently - that before going any further with reassembling the engine they should offer up the gearbox cone to the crankshaft. The reground gearbox cone, that is, the one that was reground specifically to match the reground crankshaft. The one we had to take to Wolverhampton because there was no one else that could weld them up and grind them to match.
And of course it didn't fit.
After much to-ing and fro-ing on the phone it turned out that it wasn't really anybody's fault; Custom Crankshafts had done what they were asked to do, but it had been done too far up the crankshaft, something they had no way of knowing at the time. The solution, which Brian has already put in train, is to get a new cone cast. This made me gulp somewhat, but apparently, using the old one as a pattern, this will only (!) cost about £300.
So we end the day with everybody relatively happy and all friends again, but I think some people had a few nasty moments with Jim on the other end of the phone ...
Technical moan. I've tried and failed to post a photo direct from the Webshots site, as I can't actually find my copy (the horrors of digital photography). If you want to know what the parts in question look like, it seems I can do no better than offer you a link.
