The engine I'm building requires some short 7BA grub screws only around 6 or
7 threads.   All I could find from the usual suppliers were 1/4 inch which
are far too long.   I've managed to cut them down reliably by using a single
nut as a clamp - you run the grub screw into the nut to the right length
then put the nut in a vice until it clamps the screw tight (using lock nuts
consume too much length).  Then the excess can be sawn off and filed to
shape.  QED!   If you over tighten the vice it becomes very difficult to
retrieve the screw from the nut afterwards though.

However,  I'd much rather buy them ready made!
