[GreenKeys] [ARC5] Source for #2-64 cheesehead screws?

[hwhall at compuserve.com]

That sounds like something I could do!  I've emailed an instrument repair shop to see about getting the screw & if they don't turn one up, I'll give that a try.  

Thanks!!

You could chuck up a longer, larger screw in a drill press so you coulduse the thinner side of a file to "machine" the shaft down tothe appropriate size for the die. After cutting off the chucked upportion of the screw re-threading should be possible.

>A pan head is nearer the rightrelative size, at 2.1 times the thread diameter. If I go up to a screwsize with a suitable head dia though, it looks like I'm at a thread diathat I can't get into the 2-64 die to try to rethread it. Maybe what Ineed is a micro >machinist?
