Placing simple trigger pin?

[Jerry V Lape]

Everytime I do one of these I struggle marking both sides so the pin is perpendicular vertically and horizontally.  How about some tips on how you do this? 

[Dave B]

You need one of Dave Rase's drilling jig's to get your self all lined up then run the drill though perfectly at the place you want it to be.

[Jerry V Lape]

I have a drlling jig similar to Dave's.  The jig only works if both sides of the rifle are marked correctly.  I have no trouble identifying the placement for the pin on the lock side.  The problems arise trying to accurately transfer or measure the exit point on the side plate side.

 Years back , I made up a small block  and a blade type locater .  Prior to that I used an old wood carpenters scribe
  But recently  if you look at the video done by fire lock , he made basically the same thing from an old sliding Square . Looks as if it would work fine for what your needing

For a drill press:
I cut my trigger slot first, then I slip a blade of steel in the slot, shim it up nice and solid, with 3" or 4" sticking out of the stock. This blade is long enough to put a level on in both directions, so I can set up to drill thru perpendicular to the trigger.

I clamp the bbl/stock in a vise w/ the top bbl flat against the permanent jaw and put a parallel  under the assembly someplace towards the muzzle. The trigger is clamped onto the lock surround and the pivot hole is located and marked , trigger is removed and the hole is drilled. This is done in a drill press that has a sheet of reinforced plywood bolted to the DP table. .....Fred

Jerry,
I have struggled with that for years, however, all the ones that were not perfect, still worked very well.
So I just eyeball em. The trigger pivot is within the lock inlet anyway, and usually comes out under the side plate. I level up the stock in my vise, then use the old Ryobi 18v with a bubble level, and I have yet to have one NOT work out.
I know it's not PC, and not very technical, but if believe I sometimes overthink things.

Thanks guys, lots of good suggestions.  I will try the drill press method.  Haven't been real proficient with that tool but it is time I figure it out once and for all.

Here's how I do it (sometimes).  I drill the pivot hole where I want it in the trigger, in this case 1/16" drill bit.  Then I clamp the trigger to the stock in the attitude I want, clamp the gun in the drill press vise or to the table of the drill press, square with the world, and drill the hole into the wood through the trigger.

[Acer Saccharum]

Taylor, really, 'square with the world'!!!!!

Did your mama teach you to talk like that?

[D. Taylor Sapergia]

In this case, no, it was likely my dad.  I owe much to him.

I agree with Fred, Dane, Taylor,.....It isn't rocket science.   I've drilled a lot of them just eyeballed.   I used to use the vertical
mill until I watched Jim Chambers using a hand drill to do his underlug pin holes, it really isn't that difficult...........Don

I agree, Like I have always said, "The eye don't lie."

I just completed one last week. Did it by eye, but I was paying attention when I cut the trigger slot and mortised the trigger slot on down with frequent test fittings. So I knew pretty exact where the hole would go, plus there is a bit of wiggle room but you have to be pretty close. I used a finger drill (1/16th) to make the pin hole. Its slow but you have complete control all the way down. You get'er started, go in just a bit until the drill will stand upright, check for vertical, adjust if necessary, and go on down. No sideplate on this rifle so the hole is blind, I chamfered the opening inside the lock mortise so the pin can be removed if needed but I don't believe it ever will. I use piano wire for a pin.

Peter Alexander noted that most sideplate flats were parallel to the bore rather than the barrel. Perhaps this is one reason why?
