My bo bo, sorry about that, of course he did the cranks at cost. Racers seldom charge other racers for help and this is a sterling example of that in SPADES! Who did what is well documented on vincentstreamliner.com. Gerry Jenkins has put some great video footage of Vincents in action at Bonneville, Mallory park and more .

Hi, Glen, sounds like my Wyatt cases maybe had a few less issues. Looks like you are at "the top of your game" I hope the motor works as well as your chassis, as usual, please keep us up to date Regards, roy ps maybe it was me posting about the aggravation with the die grinder!
My cases came from Conway's (don't know who makes them) and Terry mentioned that he had to do a hell of a lot of machining on the cases to get every thing to fit and work properly.
Wyatt cases
If you need new cases Bob Culver UK supplies Wyatt cases, and checks them out before selling,
Max is correct about the Vintage class in most venues requiring original crank cases, muffs and heads. It used to be that SCTA was pretty much the only game in town and all of the other sanctioning bodies copied their rules. Today there are quite a few organizations with contradictory rules. For example, I set the record at Loring Timing Association at their inaugural event in 2009. They used the old SCTA rules regarding short push rods that classify the Comet as an overhead cam machine. So, that is the class I am in. At ECTA meets I am in the "Non-Pushrod" class also, because all Vintage bike are considered "Non-Pushrod." In general it means you are competing with 750cc Harley and Indian side valve V-Twins in the 500 cc class (as well as 500cc overhead cam bikes.) That should give you an idea about who wrote the rule.
I know this is technical, but it is worth mentioning that if you plan to compete in any formal club or organization, the first thing you should do is get the rule book. Don't buy the hot rodded parts first!

In fairness to Andy Molnar, much of the case renovation was needed to squeeze in that big crank. It is larger in diameter than a standard crank, which would likely have fit right in. Terry told me that the Molnar cases are the finest Vincent crankcases made today. I would say Molnar also has a very good foundry connection as the material looks more like billet than cast, not a flaw visible anywher
Thanks Roy, but I am more at the bottom of a learning curve. Fortunately there are good books and helpful experts at hand.

Just received my top end kit from TPV. Here are some of the pictures he sent me of the new compression release machining. I have not yet asked him what type of HD unit he pictures here. They seem to only be available in pairs and are pretty expensive. The CR threaded hole is 12mm, as are the plug holes:
Hello Ron, What are you building ?, I thought you were a Standard Man !. Cheers Bill.
I am a Standard Man, Bill. This is the "Standard Comet Special" you see so much of nowadays now that us old guys need a small project to keep us entertained. TPV 600cc top, Norton Commando box, most probably a 4" top tube frame with monoshock rear, Newby belt and clutch and modern Japanese forks. I managed to find a set of bare Comet cases from Oz and I am improvising from there. You have been having so much fun with your Comet I decided to see what that was like.
