Has anyone shortened a darkroom sink?

I just picked up a 6 foot long plastic darkroom sink. I think it's about 25 years old. It's black plastic and it sits inside a metal frame. I can't find a manufacturers name on it. My problem is I want to put it into a 5 1/2 foot space. I want to cut the lip off the tray end, and shorten it by 6 inches. Has anyone had any experience trying to glue this type of plastic sink? Specifically a glue recommendation?

I guess such sinks were made from hard PVC (at least here they and lab sinks were made this way).

In this case you would need a special PVC cement that is solvent based. You would find such for PVC-tube fitting.
Alternatively you might use an epoxy-cement or (least best) just silicone-rubber at the fillet.

If its PVC or ABS then it wont be any big deal, if its HDPE, forget it unless you want to drop $75 for a special caulk gun and $30 for the glue.

Most simple way to test would be trying a little bit of that solvent cement. If it attacks the surface readily it would be fit.
At HDPE it will not show effect.

See if silicone-rubber will stick to it. If it does, should be doable.

if you do find that it's ABS, get some weld-on 16 in the larger of the two tubes available. It's a thicker solvent which works well on this sort of project. If you need to fill in gaps, ABS shavings mixed with solvent make good filler.
