Default Tip: #10 Screw Dimple Die, Homebrew Style

So, needed a #10 dimple die for the counterweight screw, but only had a #8. After checking with the local gang, no joy. Well, let's do it Bingelis style.
Grabbed some aluminum rod stock, fired up the old South Bend, and ten minutes later, done. You could also do this with a drill and your microstop countersink. I just happen to have a lathe handy.

#12 drill, countersink on extension, the old plastic fractional/decimal caliper, and some stock. Used the larger since I would end up with minimal shoulder with the smaller diameter stock.


Drill the hole:


Countersink:


Cleaned it up a bit and cutoff:


done:


Put the screw in and squeeze it:


Looks okay to me:


and yeah, I'm building in the family room...

Well, I know which "knucklehead" I can borrow one from on my next build.
