its the serated tip, running in reverse, that might just do the trick. Of coarse, "your actual mileage, may vary"

irwins smallest LH drill is 1/16". that should work down to #3 or #2-56 if you're set upbin a hi.speed drill press with proper work fixturing.

drill press?

i can show you my idea for horizontal sliding drill jig that can be used like a drill press. but you'd be encouraging my Rube Goldberg personality disorder...

I'll save up for a drill press as soon as I find a place to park it...

my horizontal idea could use your dremel...

I think I might need to see that then ;)

Slight repost, here's a pic of tools used in cutting and measuring threads on fasteners.

If you have the die for the threads you want to cut, you could buy a kit from Brownell's gun smith supply and make your own screws, scroll down on this link for the kit and refills for flat head screws,

Now I won't go into the different kinds of flathead screws there are, but let's just say, they can have different depth of head for thinner materials. And some have "undercut" heads.

My intentions were to use the original foot control receptacle box, but since I came up with a salvaged fourplex which is more to my liking. The foot lever spring is removed and friction on the lever increased to help hold in a set position of varying resistance. The control/power feed box is finished and functional. Haven't used it with an electronic foot control yet. Anyone have an idea on if it will work with an electronic control or will it blow it?

The first picture is how I thought it would end up. The second picture is the finished product.

Ron you are sssssssssssoooooooooooooooo far over my head. DH installed a dimmer and I am loving it - I use it with my Dremel.
