Got some epoxy but is there any kind that you recommend. Thinking about Gorilla glue too(urethane). Don't have the plastic welding stuff.

Going to do the epoxy and fiberglass onto plastic to fix plastic casing on hand tool.

Little off topic. Whoever decided to make the cover of walking lawnmowers from plastic needs to be drawn and quartered. Lawnmowers get hot and cool fast and shake alot. Brilliant!! /rant

I superglued a moped fender back together then did the body work and paint after it hit a bus. And no I wasn't driving it... :)

depends on the plastic type and the nature of the break and the nature of what you're gluing. need more info.

what kind of force will this part see? pulling? twisting?

Napa sells a plastic weld that is incredible. We use it all the time and it is the only thing I have ever seen actually work. It is very strong when cured. We fix door panels and all kinds of brittle plastic auto parts with it. GREAT STUFF!

Most people throw away the broken dildo and buy a new one.

outside casing. handle is connected to it. looking for the type of glue that welds the two parts a little.

something like this.

yeah, you will need something like that. Super glue and epoxy often don't work well under shear and pulling forces. Gorilla glue (polyurethane) also has the annoying property of expanding slightly when curing, which causes some issues too.

If it's styrene plastic, Testor's model cement actually 'melts' the two pieces and fuses them back together as one plastic piece when cured. Pretty useless if not styrene, though.

This is a little stronger [rated for load bearing] and more widely applicable
