I am concerned it will deform because when I did the first heat treatment required prior to machining, the block bent. I deliberately supported the 4 inch thick block at each corner to see how it would react. The bent block is not a problem, in fact it helps me. I need some guidance with this so I don't ruin 50 hours of machining.</div><div dir="ltr" data-setdir="false">If I can't find the information, I plan to test different ideas with old ports the same thickness in the oven.</div><div dir="ltr" data-setdir="false">Hank</div></div></body></html>
