Aluminum trihydrate

wondering if Aluminum trihydrate is still considered the best material to use as a thermal stabilizer and filler?

I am ordering vinyl ester resin for casting stators and am wondering if Aluminum trihydrate is still considered the best material to use as a thermal stabilizer and filler? The vinyl ester resin is from US Composites catalog # 700 Vinyl Ester Resin SM-700100

Now who said I only write gibberish in my diary and never post or comment on real projects? I searched the board first, of course, which is where I found the spelling, "Aluminum trihydrate" then I saw that US Composites sell this powder as well as the resin and glass cloth I needed, so I ordered it. Hope I guessed right. Anyway I am getting frustrated waiting for and dealing with our local community college to get what we need to build our wind turbines, so today I ordered three axle-hub assembles from E-trailer as well as the resin and aluminum trihydrate powder. I can't wait to get started on the stators. I already have a set of neodymium magnets thanks to the guys at 0therpower. Still needed is the guy wire for a 60 foot, 4inch thin wall square tube tower I am building. Anyone want to jump in and hook me up with a decent stainless steel cable source? I'm in New Mexico shipping being a concern.     Brian Rodgers

Boss, Why square? Can't say it will be strong as a round tube. Joseph [ Parent ]

Brian With you being in New Mexico I think stainless steel cable would be way over kill. I would just go with a good galvanize cable and use the money saved on the rest of the system. Stainless isn't cheap. Old F [ Parent ]

Square because that is what I have. Can you believe the price of steel of late? Maybe it was just the place that the college was getting quotes from, but  the quotes were through the roof, freaked the bean counters, may have put the whammy on our plans. Brian Rodgers

Why not scout around and find/use some recycled pipe or angle. Many recyclers have good useable lengths of steel tubing . I was lucky enough to scrounge some 3x3 angles from a tv tower that was being "up-graded" Perfect. My tower is 65 foot,I bolted the angles back to back ..some pic's in my album,"irc album", Brucedownunder [ Parent ]

I hadn't bought new steel for about 8 years  so the last time I went I was quite surprised that what was 50 dollars worth of steel was 350 now  ouch! [ Parent ]
