Hi,

I am making the crankshaft webs for my No.4 and have decided to incorporate counterweights onto it.

What do members think will look better a 15 or a 30 degree back rake.? I have drawn aprox onto it the 2 angles that will be carved out to help to visualise.

Cheers, Nick

I hate you.!

But I admit that it would look good.
