You're moving along on this quickly, Ron!Did you do any stress relieving on your cold rolled steel? If not, you might want to do that. It can have a tendency to go banana shaped when you machine it. I also know that some people just make it then bend it back straight again after machining. That hasn't worked as well for me, but some people seem to do it OK.Kim
Kim, whats it take to stress relieve crs? I've done it for brass, don't know the process for cold rolled.
Did you do any stress relieving on your cold rolled steel?
Ron, you mentioned you had intended to buy hot-rolled instead. Does the hot-rolled version not need stress relieving like cold-rolled does?
There is also something called stress-free steel available, but apparently only in round bar form. Brian Rupnow has discussed using it to good effect for crankshafts, but it does require extra work to produce a flat bar.
