Have a look at 'Gorilla Glue' John.

Hi 2517


What about liquid nails. Once it has set, you will never get the handle off.

What's a craving knife?

polyuathane aquadere glue. Make sure it is not pva,
I will bubble up out of join for a while but dont wipe it off, wait for it to dry and trim with a knife. Needs 24 hours to set and needs to be clamped. Don't glue clamp to the job. I use news paper between clamp and job. There are easier products to use but nothing better.

John, Devcon have an excellent product that I have used many times. It is called Plastic Welder and is good for bonding hard plastic, concrete, metal and so on. It is similar to epoxy and you can buy it at Blackwoods, RS online in a 25mil 2 part injector syringe style package.

Hers is a LINK to what the product looks like and it's specs

Nobody has mentioned the old trusty favorite so I will.

Selley's Araldite, a two part epoxy adhesive. It can be purchased in small sized tubes or a double syringe type container.
Use the "original" araldite, not the 5 minute one.
Lightly clamp or tape to stop handle from sliding and leave for 24 hours.

If the handle (which you say is plastic) was heat proof, you could have placed in a moderately hot oven and cured the adhesive in 1 hour.

Araldite the slow curing one
