Hi folks,

I am looking for a flat screwdriver with an exceptionally thin blade,
for use on clock mechanisms. The blade needs to be at least 3/16" long,
but no more than 25/1000" thick. Does anyone know of a source for such a
screwdriver? UK sources are preferred, if anyone knows of them.

I know I can try grinding my own, but I'm not convinced I can do it neatly.

Follow-ups set to rec.crafts.metalworking.

Many thanks,

Chris Tidy

You're letting your name get to you.

It doesn't have to be tidy, it just has to _work_.

By 3/16" long you mean it fits a 3/16" diameter screw head?

I have a set of "precision screwdrivers" from Radio Shack (US), the
largest one is 9/64" x 0.025 or so. You ought to be able to grind this
freehand on a wheel -- just hold some 3/16" rod straight down to get a
nice radiused cut on each end. I'd be tempted to grind it to a knife
edge, then go straight in until I'd achieved my desired thickness.

Do you need to implement control loops in software?
"Applied Control Theory for Embedded Systems" gives you just what it says.
