Inletting trick- or: how to gage your depth
« on: August 11, 2012, 07:27:35 PM »
When inletting a barrel, lock, etc, how do you know you're getting close to the bottom of the inlet?

I use inletting black, very dry, on an old toothbrush. You can't really see the film it applies, so it's not very messy. Maple is a dream, because it's so white, the least little bit of black shows up.



I know I'm getting close to the bottom of the inlet, but how close? I certainly don't want to take too much out from under the tang.

So roll up a little ball of silly putty, modeling clay, or old chewing gum, and lay it in the bottom of the channel. It's in the channel, near the breech, about 3/32 in diam.




Set barrel in place, as far as it will go. I use a soft mallet, then really set it with a piece of endgrain maple and a hammer, and also set the barrel against the breech, by endgrain and hammer at the muzzle.

Oh, baby, look how flat the little ball of clay is! I can see the tang needs just a touch of wood removed, oblique flats in the channel can be scraped a bit, and I'm there!

Silly Putty can actually be measured with calipers and light touch.

Thanks, Eric. After doing it 20 or 30 times, the inlets start getting better.  ;D

That inlet was obviously done by a professional using a machine.  Mere mortals cannot inlet like that!!

Wow!! What clean inleting. It would be easier if you told us how you get the maple to grow around the barrel. Thanks, Mike

There is something bothersome about that...............

BTW my dentist gave me some strips of black and red paper he uses to determine the fit of teeth in the bite or the height/clearance of new crowns being mounted.  Very nice and clean  for testing the depth of inlets and fit of whatever you are inletting.... dentists have the neatest gadgets...

That's a great idea Tom. Same concept as "plastigauge" used to measure bearing clearances except that the plastigauge has a scale where you measure the WIDTH after squeezing it to get the thickness/clearance. The stuff is cheap and comes in several thicknesses for different clearance ranges. http://www.plastigaugeusa.com/how.html
