I had a tough time machining the surfaces that were flame cut from the other ring I machined. I am thinking about heating it in an enclosure with a tiger torch to take the temper out of the surfaces that need to be machined. Will this work and what temp should I take the part to. The part will be non structural when completed.</div><div id="yui_3_16_0_ym19_1_1463869625805_2569" dir="ltr">Hank</div></div></body></html>
