90 gallon acrylic sump.

Bead of weld on 40
Heavy metal gravitational clamp. Bonded only the bottom edge.
Day 2 the 16 penny nail gap maker. On the opposite side.
16 penny nail with poor penatration. But it is sealed on one side, about .007 gap.
The blue tape is backing.
Day 3 pour seams to fill voids. On 16 penny nail side.

The dark edge is from the sheet of 1/2" polycarbonate bonded to acrylic. The polycarbonate was a freebie, so I am going with it.

A cathater tip 60mm syringe work great as a caulk gun. As it's too thick for a regular needle type syringe.

Blue painters tape as backing worked great. As it will still pull off after the cement has gelled after about 45 minutes. A razor will cut drips well green.

Day 4,
Fixing some saw kick back. The 3m painters tape peeled off cleanly from the freshly cured acrylic.
This is polycarbonate green, to clear weld-on 40.

Day 5
Set up on 45 degree jig

Syringe applicator with catheter tip is reusable with just wiping down with a dry paper towel. The old Lincoln makes a nice squeegee to unload a zip lock back for bubble less, odor less mixing.

Nice clear fillets, except were the tank bowed out in the center section. Crazing is made visible
Corner holes. For the openings on top.
Needed some quick holes to finish all the internal fillets as the weather is going to get too cold here in 2 days.

Anti suicide rails, to hold any jumpers and mitigate water drips.

It will also anchor a back splash wall, for the sieve screen.

Sieve build layout. The bottom will end inside the 2nd chamber. That's going to hold filter socks.

It too cold to glue with out firing up the big furnace. So I might try gluing it with something that I can do inside.

Proto typing engineering as I go.
Using DAP Rapid fuse, then will fortify with weld on 40.

The rapid fuse is nearly odorless, and sets up in 30 seconds. About as thick as weld on 16.

It can also be busted apart and reworked. For prototyping. Sweet

Wet test run of sieve.

 

[markstrimaran]

Dap Rapid fuse on PVC to poly carbonate. The coupler is waxed.

Weld on 40 thickened into peanut butter consistency putty, with 3m microballons.
After a few minutes it skins over and can be smoothed with a nitrite glove with out sticking.
