I had found an excel spreadsheet created by Guy Wilson, that calculates
the linear (not circumferential) distance between mounting holes, given
the geometry of the PVC and copper pipes.  I've never tried it, so good
luck!  But even assuming the best, I'd not throw out the rat tail
file...  I'll ask Terry to post this to Hot-streamer.com
