Re: [Killietalk] Acrylic bonding

["Robert Tucker" <tucker at covad_net>]

Thanks for all the replies. I went and got some methyline chloride (+ other
stuff) for my project. I'm not building a tank (no leaking issues) but
simply a rig for adding three dividers to a regular glass 20L. I synthesised
my design using ideas from the list and a rig I saw on aquabid.

I'm taking a scrap piece of 20" by 8" by 1/2" plexiglass (very heavy) that
will rest on the bottom of the tank and gluing acrylic U shaped channels to
it that will hold  1/4" plexi plates snugly in place for the dividers. These
will be sealed with slit aquarium hose at the sides. I'm going to cover the
plate with a sand substrate when in place.

The only thing I'm still working on is a fry proof way to let water
circulater from compartment to compartment.

Thanks again for all you help.

Regards,

Tucker
