We have used it to adjust tilt angle for various mechanisms that do not have a lot of overhanging load.

After broaching 3/8" hex, the plastic coupling is fairly thin. Has anyone used this method and loaded it heavily; e.g., torque > 100 in-lb?
We've also had a good experience broaching 3/8". Not sure if it reached full loading but it was pretty close.

I also tried adding a 1/2" socket bit and filled the gaps with epoxy. Haven't torture loaded but it was holding up for some mid load prototyping.

Just remembered we did some torture testing. Information is in last years thread about half way through. https://www.chiefdelphi.com/forums/s...sch+seat+motor. I should point out that this was using a rotary broach which doesn't quite give you the flat sides that a linear broach provides.
