Hi David. Im interested in building a heat tratment oven for Aluminum
shafts for the purpose of streitening them. Do you have any insight you
might can share? Thanks.

How big are these shafts? Aluminum bends very easily. With a small
hydraulic press (about 5 ton) you can straighten shafts up to 1"
diameter with no trouble. And they will retain the same heat treat and
post heat artificial aging that they started with.
