Re: [PSUBS-MAILIST]



Greg,
Am wondering what the thickest acrylic was that you blew domes from
or were they vacuum formed?
I have a guy here in NZ vacuum forming a 35mm x 550mm dome,  he says
he is going to press the apex up to aleviate thinness in that area any thoughts on this?
Regards Alan

Polyesters have excellent resistance to acids but are readily attacked by strong alkalis (such as soda lime). Battery acid mixed with seawater can produce chlorine gas.  AGM batteries are the safe bet these days.

Thanks for the great tips guy's. I like the stainless steel battery tray idea but should also treat the bottom below it as mentioned. Does fiberglass resin react to battery acid?
