Thread: How to Remove Pins from Your Straights

I am removing all material that Lerch may find offensive or construe as a personal attack... bye bye, now...

Thanks for the updated info Bill,
What's a good online source for the specialty drill bits?

Hey Bill, as usual, really good info.

I am removing all material that Lerch may find offensive or construe as a personal attack... bye bye, now...

I used the same technique and a real dentist's drill bit. It's cone shaped and (i think) diamond coated... Just ask your dentist if he has one to spare

What did you put the dental drill bit into? Rotary tool or regular drill?

I picked up 50 micro drill bits on ebay for about $15, and that's with the guys F'ing me for $10 shipping when the package had $2 postage. All were regrinds and were carbide, so they don't flex or dance around. They are small enough that I've drilled directly through a pivot pin to the opposite side, though I didn't attempt this with my favorite pair of scales! Carbide tends to break easily, but at 0.30$ a peice, what the hell.

I've also got a few dozen brand new carbide dental drills and end mills which are great for cutting detailed inlay and other small projects. All are still in the original condition, some still have the wax covering the blades. If any one is interested in some, I could part with them for about $2 a piece, which is what they cost me.

I'm currently having good success using a small 2nd cut file to get almost down to the scales..the washer is then almost gone and it pops off..cut with flush cutters and gently tap out with a 1/16"flat punch. I find it much safer on celluloid scales I want to use again..no heat.

I've been meaning to pickup one of these. It's a drill & rasp set that's been retooled from the electronics industry. 50 pieces for $25 CAD. Not sure how well it'd work for removing pins, but I'm sure they'd at least come in handy elsewhere.

Them's the best. Very fragile though. high speed, you can run up to 40,000rpm for the smaller ones. I should know..we use then in PCB manufacturing. They take about 10,000 hits in our CNC machines.

ps Great price..very cheap.
