<div>Brian,</div><div>If I form it, yes I will make a form. I happen to have the correct size steel head here I can use for the form. The window is only a hemispherical segment, so not too big. I have to keep it under 26 inches so the ring (seat) will fit in my small lathe. The oven will be the size of a old school phone booth, remember those? ;-)</div><div>Hank</div><div><br></div><div><br></div>

I can find all the references to the rules but not the rules. I am planning to make a 5 inch thick 60 degree Hemispherical segment either from forming or from machining out of a thick slab.
