I used the original 2-part JB Weld epoxy which has a higher strength rating, but the urethane type mentioned in the post above might be better because it might remain a bit flexible. The main thing is to mix up plenty of material so it fills all of the voids between the metal and plastic. I wiped off the excess that squeezed out after applying zip ties to secure the plastic handle. That reduced the need to sand, scrape, grind the excess material away after it cured. Make sure you leave the zip ties in place until the epoxy has fully cured.
