Wonder if it is the nuts on the raising block, jacking the bed up?

Sloppy & Tight on BSW/BSF fasterers!

Robert Butler

In the RAF we had two specially bent screwdrivers for the screws on the alternator connector cover. They were straight slotted screws and you could only turn them 90° at a time before swapping to the other screw driver and doing another 90°.

Chopping and modifying spanners/wrenches was a regular occurrence when I was at work. Heating and curving 27mm combination wrenches to fit around pipes for tightening flange nuts was a frequent request of the welders with access to oxy-acetylene. We also made curved tooling to fit on the end of spigotted torque wrenches for similar reasons. We set the torque value for these tools on a calibrated torque meter. There were quite a few half spanners welded at 90° on a long bar to reach where other tools could not go.

I think making and modifying tools is a standard engineering role.
