I have fitted a DRO to my tailstock so I use this to check my progress, once I get close I stop and blow some air into the shank, it chips spray out i know I have hit the airway, if not I advance another mm and try again. Once I do get chips, i slide back the taistock and shine a torch in there to see my progress, from this I adjust until the airway makes a nice teardrop shape at the bottom of the chamber.
+1 this. Except I use my lungs and get sawdust in my eyes :)

Picking sawdust out of your eye is a skill, just like ninja skills :)

I'm a sawdust ninja.

That skewer idea sounds like it would work pretty good.

I mark my bit a little short and when I'm close I shine a flashlight down the shank and look into the chamber. When I'm real close but haven't hit the airhole yet, the bottom of the chamber will glow through the wood. Like holding your hand over a flashlight, you know how your hand turns red? Like that. Then I just drill a little deeper and shine the light in the shank again. I can see the hole alot better shining the light through the shank than I can when I shine it in the chamber.

If it works for you then great, I have never drilled on a press so don't really know the good methods.

As to air, I always keep the compressor charged so I can do jobs like this, blow through stems etc. I actually have 2 compressors, one large for the sandblaster which gets used just for that, and a smaller more portable one, the small one gets filled up and then switched off, it doesnt leak unlike the larger compressor so a charge lasts me several week of light use before it needs topping up.

I used to have the same vice.

1)Unscrew the thin inserts from the jaws, then go and make or adjust the inserts to have a pin in their center.
2)Use them by nailing them in the point where airhole and bowl bottom meets.
3)Drill the airhole first and then with opening the vice as much as the block is free to rotate but with the pins still in it drill the chamber.
4)100% success

Same here, I usually do this 3 or 4 times before I get the depth to exactly where I want it...

Michail, I love the idea but with the size of some of the blocks I use it would not work as the vice is not deep enough to allow for rotation.

I had the 100mm jaws opening model.
I made inserts of 9mm thickness each, did an extra hole in the vice body center-and-lower of the other 2 and made the inserts 24mm bigger to the top.

I ended up having a 81mm opening vice(whick was great cause the thicker briar I've ever worked was 67mm) and the space to rotate almost every pipe(except a Group6+ dublin).

Trust me it will save you time, money and briar.
