Sump center brace

[MikeDeL]

I have a center brace in my sump I need to glue back in place. What kind of weldon should I use and where can I get it?

[::pete::]

Its just acrylic to acrylic and ithe pieces are flat and clean? Use #4

[MikeDeL]

The acrylic is flat , but there is some old adhesive there. Should I sand down the area first?

[::pete::]

Cant you turn it over?

[MikeDeL]

Turn what over? the brace?

[::pete::]

Yes the brace ... sorry.

There is adhesive on both ends of the center brace and on the side brace of the sump. Here is a pic. I am holding the center brace and and the bar running behind it is the side brace. The seam on this thing just came apart.

Then as you said try to get it smooth so both surfaces touch the best you can and either use #4 or #40 in my opinion. The 4 will work, but there might be voids because of the pieces not being smooth. Then if you use a thicker deal like 40 it will fill the voids. I would imagine 16 should do it also. I personally like 40 better though.

Regal Plastics sells it. They're north of 183 on Metric. I always use #4.

If I understand the situation, your center brace came loose from your sump? How did that happen, did it just pull apart from the pressure over the long haul? The reason I ask is that solvent welded joints on acrylic almost never come apart unless there's alot of pressure or something was wrong with the joint in the first place. It's not like a glued joint where the glue can just get old and stop working; the acrylic is literally welded together. What's even stranger is that you say there's "adhesive" on the plastic; meaning maybe it wasn't solvent welded in the first place.

Anyhow, this leads me to think there might be more to the situation here; if you need a strong acrylic to acrylic joint here and the two pieces do not mate PERFECTLY, then your best bet is weldon #40, with the sump drained of course.

This is the sump I got used from Alex.... It was handed from one person to another. I have no idea how it came apart..... Let me rephrase that. One side was loose when I got it, the other side got knocked loose by accident when I was working on it. This thing is empty so it wont be too much of a chore to fix it now.

I just thought of something..... This thing is actually a wet dry Im converting to a sump. This center brace may not have been intended to provide strutural integrity to it. It may have been there just for holding up the media boxes, and that is why it was just glued into place instead of being solvent welded.

So now that I am going to solvent weld baffles in will I need this brace or will the baffles act as the bracing for it?

The baffles will definitely help what size and how tall is the box?

Mike, when I picked that thing up it was really covered in dust, a lot blew off in the back of my truck. If it was a glued joint, sitting dry for long time whith who knows what stacked on it could have worked loose that brace. I kinda thought it was a commercial looking unit, not a custom job - so that might be part of it too?

[MikeDeL]

The deminsions are about 36L x 11W x 11H. The acrylic is 3/8" thick. I will probably have it about 3/4 full and the baffles will be about ever 12".

The baffles should handle it with a problem.
