[TheForge] 36" diameter ring

Wed Aug 6 16:59:15 2003

Which makes me wonder if there is a way to figure the limit to the flange
thickness/diameter bend ratio.  I imagine the 20-30 foot dia. would easily
bend in one pass... would there be a point at which it would take two
passes? Just curious, as I never expect to be involved in such.  Though I
could imagine a 4" leg of angle iron being the top of a round table that
glass or wood sat on.  Need more machines and a bigger shop ;) KD

	Back in the bad and sad days of Phoenix when I was at the shop
	in Mesa, we used to do our tough ring rolling at a friend's
	shop.  He had a hydraulic roller.  One day I showed up and he
	was rolling arcs, 4" x 1/4" on edge, cold.  You go REAL slow
	and steady, but damn if that contraption didn't roll perfect
	segments of a ring that was 20 or 30 feet in diameter.  I was
	duly impressed.
