"The crankshaft hole shall have a maximum diameter of 7.00mm at its end. The hole can be finished with a continuous unbroken chamfer with a maximum width of 0.50mm, if this is required for manufacturing purposes at the crank web end"
(Crankshaft drawing equal to one on page 141 for the 1/10 IC Track Class).

ah, that's what I meant....
Where can I get the EFRA rules, or rule book? Do you have a link?
