The question seem to come up, and some people have asked me... so I thought I'd drop a (rather terribly big) file here into the list serve. Please accept my apologies if this is too big (it sort of is), or unwanted, but here's a simple Word document that gives at least one way to start this process. I really need to make a follow-up that shows how to do this with CPVC plumbing and electric hot water heater elements... but if I want until I have it "the way I like", it will never be done... Any questions, just ask! -- Brian Davis -------------- next part -------------- An HTML attachment was scrubbed...
