All,

The gear has a dial with a small, striped allen screw. The tool is 1.5
mm. Any thoughts on how to get this off?

Thanks - Dan


If it's not countersunk, a small pair of vice-grips does nicely. I
have even had success using small haemostats. If it is counter-sunk,
there are any number of extractor-bits available for your drill.

If it's not countersunk, there are obviously far more options.

When taking things apart to salvage some parts, I've used a cutoff
wheel in a "Dremel" tool to put a slot in bolts that have unusual
heads (usually there to prevent tampering). Slice a slot across
the top, then use a regular screwdriver to remove the screw.

Of course, it doesn't work if the bolt/screw is embedded.
