For a demonstration (and a great excuse to finally follow through), I made a drawbore pin!
This is an old tool, used to test fit and align mortise and tenons using an offset peg.
The idea, is if you drill a hole for the peg through the mortise with a brad point or auger bit (with a lead screw), then insert the tenon, use the bit to mark the center of the peg hole.
Remove the tenon and drill a hole in the tenon cheek closer to the shoulder. Maybe a 1/64 in hard woods, a 1/32 in softer woods.
Anyhoo, this offset hole in the tenon lets you drive a peg that will pull the tenon shoulder really tightly to the mortise. So tight, you can do "sloppy" work on the tenon and the joint will be as tight as a piston fit machine cut joint!
(Yeah, I'm a Schwarz Devotee, so I'm using lots of "his wording")
Well, you test the fit with a tool called a drawbore pin. Its a tapered metal rod that you twist into the peg hole.
The nice thing, it lets you test fit your frames (say a face frame) and adjust as needed without the need for fancy clamping.
Long way of saying here is my first of a pair of drawbore pins I made.
I got two 3/16" Alignment Pins (part #44022 Baltimore Toolworks).
Pulled a nice "quarter sawn" piece of red oak firewood off the pile. Split it up, and worked it to shape with chisels, spokeshaves and scrapers. Ended by burnishing it with the shavings.
I like the oval handle, like a mortising pig sticker chisel. It feels good when you twist it into the peg holes!
If you can't tell, I had a lot of fun making these
