I've got a problem with my AC/DC Premium Cannon : while turning, it stops in the middle.
When it stops, I can still hear the motor running.

I didn't find any part that could block the cannon in this position.
It seems to me that the cannon crank slips onto the motor shaft.
I assume that the crank/shaft screw got loosened and I wanted to tighten it.
However this screw is not a metric one and I don't have the tool to do it (I'm in Europe). Moreover, this screw is not easily accessible.
The screw is a "10-32 x 5/16" one. A 2mm allen wrench is far too small, and a 2.5mm one is just a little too big.

I'm about to countersink my 2.5mm allen wrench, but I wonder if somebody has a better solution ?

Tightening the screw did not help.
So I checked again and found that the cannon was touching the right ramp while moving (I don't know how I missed it the first time).
Adjusting the ramp solved this issue.
