Well, look what that just led to! Excellent tip!


From:

Glueing plastic with super glue + Bicarb of Soda - Woodwork Forums
Here is my tip. Set up your joint however you can by clamping etc until you get an almost perfect fit. Dribble in some superglue and then reach for a pinch of Mum's BiCarb of Soda and sprinkle in onto the superglue. It will set like concrete (and about the same colour) in less than 1/5th of a second. It gets hot - dammed hot so don't have any superglue on your fingers when you reach for the bicarb.

Superglue won't fill a hole like epoxy.

Not on its own, but whatever it turns into when mixed with the soda is incredibly tough.

That may be true but I am wondering how it will set up and why you would to go through that? It just seems like epoxy is ready made for the project.

That quickly?

"It will set like concrete (and about the same colour) in less than 1/5th of a second. "

If the hole filler is harder than the surrounding material, any screw you put in will walk off center around the filler. The epoxy may be a least roughly similar to the plastic.

Epoxy, would be the first thing I use if I had some standing around, except where you have to build external bits, not haveing any, the superglue would be my way. You can always drill a pilot hole through it for your screw.
