Got a weed whacker that has a black poly/plastic rotary head on a motor
shaft. The shaft is approx 1/4" dia and 2" long.
The head was originally a press fit onto the shaft. Somehow, it has
loosened and now the rotary head comes off periodically.
I'm trying to fix it, and need ideas. I just put some locktite on it today,
and stuck the head back on the shaft. However, locktite says use only with
metal. I don't know if it just means it won't work with anything but metal
or what. I'll know tomorrow pm if it works.
Assuming it doesn't, what else can I try? JB weld? Ideally I'd like to
drill through the roary head housing and shaft, and cross pin it. However,
the out diameter of the housing I'd have to drill is approx 5"---too wide a
span for my bits.
