Allright guys, I'm back on this one!
Never tried the air hose, yet. Initially it seemed too complicated and expensive, so I went the rubber band method. I've since worked the kinks out of that, and have enjoyed some sucess with it. I may switch to air hose as I build new forms, but am not sure. I can wrap one in rubber in ten minutes and can't make any better glue lines, so I may stay with what I know. I think it inspires the new bowyers.
It has been cold, and I have been shopping for heaters. I bought a 18,000 BTU model that wouldn't quite heat my double garage shop. I just want to get it around 65 or so for glue-ups and spraying finish. I finally went and bought a 30,000-50,000 BTU model that is used for construction sites. It will warm my garage up from 40 deg to 70 deg in an hour on the low setting. It eats up the oxygen though, so I have to be careful. Luckily my garage door has about an inch of space all the way around and gets good/bad ventilation.
I did this glue up a week or so ago and had a set back. I heated the smooth-on in the microwave oven to thin it out some. I got it too hot! It started to act really strange while spreading on the second piece. The tub of epoxy should have been cooling off at this point, but was gettig hotter! It started to gell on me, and was a solid blob within minutes! Lesson learned. I sent Kenny M and urgent request for new materials and he got them to me asap. I will hopefully get this one layed up tonight.
Stay tuned!
