Acrylic Questions

I plan on building a sump for my new tank out of acrylic. Here are some of the questions I have:

1. What's the best way to cut it? I've read several places that you should score it by using a razor blade and then snap it off afterward. Does anyone agree or disagree with this?

2. What thickness should I use for a sump that will be 24"x13.5" and will be filled with about 12" of water? (That's roughly 17 gallons)

3. How will I cut large holes in the side of the sump for bulkhead fittings so I can attach an external protein skimmer and pump?

4. What sort of aquarium-safe glue should I use to attach all the pieces? Should I simply use the epoxy they sell at the stores for gluing live rock together?

Well sumphead and i have been doing alot of work with acrylic lately. We use a 10'' table saw witha finishing blade on it to cut the acrylic. We use 1/4'' acrylic for the sumps. To glue them together we use Weld-on #3 and then to seal the seems we use weld-on #16. You can use a spaid drill bit or a whole saw. Go slow when using a whole saw so it doesn't melt.

Okay. I'm also curious what glue I should use to attach the PVC together? (Never worked with PVC either)

It might sound like a smart answer but PVC glue to secure PVC. Its one of those things you can find next to the PVC in the hardwarestores. You have about 10 seconds to work with the two parts when gluing before they are bonded. This is why you need to dryfit everything and only start gluing once you like how everything dryfits. Smear some around the inside of the fitting and then insert the other PVC and twist slightly to get a good bond around all of the PVC.

I would like to know, where you can get this "Weld-On" stuff. Local Hardware store maybe?
Thanks,

Mike

Thanks for the info. I actually knew about PVC glue, I just didn't know if it was aquarium safe. Is there anything I should stay away from as far as glue goes?

I am taking a road trip Wednesday to Indianapolis for an Electric Show at the Covention center. Where exactly do you get this stuff? I figure since I will be there I might as well get it there too..LOL
