All the geek opinion and doomsaying in the world can’t beat a crusty old Chicano machinist in a crusty old machine shop.
After Googling and dialing all over Hollywood, this Los Feliz and Glendale in search of an EDM-equipped shop, price I phoned a local machine shop and described my two mistakes.
“Ehhh, abortion bring it in, we’ll see what we can do,” says the crusty old voice at S&K Precision Engineering Co.
So I bring it in. Within an hour and a half, I get a call saying “It’s all set.” They drilled in with a carbide bit (probably a better one than I used, and used an extractor on one broken tap, and a punch on the other – and now the holes are cleared.
The guy even took pity on me and told me the secret: countersink the holes from now on before tapping them – and use some cutting oil.
Done. I’ll be attacking that just as soon as the best little hardware store in Silver Lake restocks their 6mm Irwin thread taps. The ones that I seem to keep steadily depleting.
