When a .004” runnout conversation turns into a conversation about the factory being too fussy with a .001” tolerance, the guy loses me pretty quick. He checks the runnout with the crank held between centres, that should be clue right there. His first mistake was arguing with you Andrew - he could BS some of us..but guys from the county?? Forget about it! I'm pretty sure John from Tripp Cycle spins a pretty good tale too.

It frustrates me because in my trade our work is checked 100% of the time. No one ever takes our word for it. When we farm something out, we do the same when parts come in. We hold our vendors to the same level as our work and that means 100% is within spec. There is no doubt in my head, I’m a tough customer but when vendors are good, I praise them just as much as I will trash the one’s that are not.

Agree 1000000% Why do you think I won’t build triple cranks for other people ? I am way too picky with my own big singles, and my other stuff, I would never be able to charge enough to make it worth the time invested

I have been using Jeff at NH for 30 years. I always check runout and every crank has been 0.001".
My 0.02

The real work involved in rebuilding a crank is not in the disassembly and reassembly.It is in the time it takes, and what ever it takes to get the crank straight, and true.Some crank builders will put the time into a crank and disassemble and reassemble it and don't want to put the time involved in getting it 100% true, and in some cases can't get it with in spec.We ended up getting all the tools etc and started doing our own.Over the past several years the cranks we have built, coming out of the engine cases worn and tired had an average run out of .005 -.007 They ALL went back in with a run out of under .001 The biggest mistake people make when getting a crank rebuilt is they shop around for the cheapest price and think that they will get quality for low cost ? And just to give perspective of what quality costs ? Having Fast By Gast rebuild you a triple crank will cost you $1200.00 US FUNDS.The old proverbs that apply are "You get what you pay for" And :" How come people don't have the money to do something right the first time ? But will always find the money to do it right the second time" ? "Do it ONCE and do it RIGHT" ?

I don't know HOW those two sad face Icons got in my post.I didn't intend to include them. Probably sad you would pay 1200 USD for a crank rebuild. Just because of Pauls name. Not knocking his work, it has proven to be top notched over many years. Charlie who is regarded as one of the two top crank guys, gets a whole lot less than that And I have never heard a single bad word about his work. porscheDave in California is the other of the two I mentioned, albeit a bit far from where you are. Charlie even offers free return shipping, if you know anyone who crosses the border now and then. jmhFo Charlieporschedave

That is why we got all the tooling and build our own now, right here in CANADA. In house in our own shop. Add the cost of shipping to USA and US Dollar exchange rates and the possibility of customs and duty etc....Any where you send it in the USA, It can get really costly even if it is not to FBG. It is certainly cost effective for us to do it in house. In our shop. We don't have to send it "any where". And we can put it on the V blocks put a dial gauge on it, and straighten the crank, and check and verify the run make sure it is right.

To give people perspective In my shop - a single cylinder crank rebuild is $350 plus parts Carrillo Rod - $600 New pin - $95 Labour - $350
Just shy of $1200 after the good old tax man
That is on some of the TT/XT/SR 500 cranks I have built for ice racing for a few customers. Motocross cranks - it’s cheaper to buy an OEM crank for $700-1000 and then verify runout yourself - I had a KX250 crank from kawasaki that had 7thou runout in it - how does that get through quality control ?!?
