Precision screwdrivers question

[Mark G.]

Good afternoon.

I periodically find myself working on equipment that uses slotted screws
with unusually wide, thin slots. For example, a Bolex 18-5 8mm projector
uses some screws with slots 5/16" long, but only .035" wide. A standard
mechanic's screwdriver that fits this slot is only about 3/16" wide and will
tend to damage the screw.

Any suggestions for where I might find appropriate tools?

Thanks

A power screwdriver + a grinder is my suggestion. I find that a power
screwdriver most often leads to less fastener damage. A grinder allows one
to shape the bits just so.

The can opener / knife sharpener my wife tossed out is now on my
workbench at work. That tiny grinder is just dandy for touching up
Xcelite 'greenies' and other flat drivers. Its so wimpy it's almost
impossible to overheat the metal and it doesn't take up much space.
