[QUOTE="greg brillus, post: 179204, member: 597"] I've built up several cranks using Maughan's new wheel/shaft assemblies, plus their big ends to match.......generally with stock Vincent rods......We luckily have ARGO rods here in Australia that are the same beam shape and similar weights to the Vincent rods.......The Maughan products are magnificent to put together, and they true up very well........old flywheels that have badly worn or spun shafts I don't even bother with anymore.....not worth trying to reclaim them, and too risky as well if something goes wrong......Its more a "Cost effective thing" rather than me simply giving up on repairing the old ones.........Not unlike old wheel hubs or cylinder barrels.......If the bearing sockets are worn or if the barrel specs are too far out, I just scrap them........If you consider the time and effort to strip a wheel right down or an engine to the bare crank......you have to seriously think of this unless you are happy to do it all again........ The thing I like about dealing with Maughan's is they always ask questions about the sizing of rod big end bores and so on.....Many times they have supplied me with slightly over and sometimes way over sized rod liners to correct rods that are oval.......this is very common at least 50 % of rods the bore is not round.......This should be honed back to being round first and then measured to get the correct size of liner and interference fit........Both Steve and his son Lee are very helpful here.......Great guys to deal with........Cheers.
