Hi again, on my Nash the crank nose is very short, approx 24mm from the front of the cam drive sprocket to the end of the shaft, before the diameter reduces and a thread is machined on. The original nut is present that is wound onto the end to tighten the front pulley. This arrangement is not great for me as the 24mm is not long enough for good support, I am proposing to machine in effect a nut with a finished round outside the same diameter as the shaft, when permanently fixed on I will have a much longer crank nose which will be good for supporting the blower and accessory drive pulleys.
Can anyone suggest why this may be a bad idea, or a better solution? I could have it built up with weld then ground down to size, but as the crank is so old I'm not keen on this. I intend to drill and tap the end of the crank to house a bolt to tighten the pulley up, like a RV8 crank.
Cheers in advance!
