I am getting ready to assemble my workbench with drawbored Mortise and Tenons so I wanted to make a drawbore pin. From what I understand having one of these is not absolutely necessary but they are helpful and increase your chances of success.
Also, since I wanted to try my hand at drawboring on future furniture projects I decided to make a smaller one for furniture scale joinery.
This article by Christopher Schwarz gave me all the information I needed.

His handles aren’t turned but from what I understand turned handles will work ok as long as they are a little bigger to give you a lot of grip for the twisting and turning you will be doing.
I also found some 1” brass pluming thingies that I was able to cut down and use as ferrules. Pretty easy to cut with a hacksaw and I think they add a nice touch.
I didn’t use the torch to heat the tang before inserting it into the handle. I had the torch and everything. I guess I just chickened out. :-) What I did instead was grind down the ridges on the octagonal tang. This gave me a tight fit that I was more confident banging together with a mallet. That and the ferrules prevented the handle from splitting. I think they will hold up fine.
One more tip that I read somewhere. Since I don’t have a metal working vise. I slipped a small washer over the tip of the pin and drove the tip into a piece of pine. The washer lets you hammer the handle onto the tang without splitting the pine. I was worried about the washer scratching the pin but that wasn’t an issue.
The wood is walnut finished with shellac and wax. I got the brass pieces at Home Depot and the pins from Harbor Freight. Each tool took only a couple of hours to make.
I’ll let you know how they work out.
Thanks for looking! Questions and comments are welcome.

Those came out real nice and they going to be very strong
as the wood is really only a cover and the pin itself is the strength
they are better than the ones available elsewhere

Nice work Mauricio, they look great. I blew out 2 of the joints on my travel plane till with the draw bore pin. One of these probably would have been a good idea.
Look forward to the bench assembly too

I had to do some research on what a drawbore pin was and how it functioned. Come to find out it is the woodworkers version of a tool I used for years as a Ironworker. We called them Bull Pins or Drift Pins. We had another name for them but I won’t repeat it here. We used them to align the bolt connection holes between beam flanges and columns so that we could insert the bolts. They weren’t as delicate as these nor as pretty. Great job Mauricio.

Thanks for the great comments everyone!
Mos, what caused the joint to blow out? Was the offset too big? Or are you talking about the back of the joint where the pins exit the hole? I want to make sure that doesn’t happen to me!
L2L, that’s exactly what I used for the pins I got from HF. It’s a metal working tool repurposed for woodworking.

Very nice work. Mauricio

The difference in the two techniques is that the drawbore joint is intentionally made off-set to pull the joint tighter and supposedly stronger.

Thanks Jim!
Gary, thanks for that link. I also liked the idea of hexagonal handle and a round ferrule but I could think of how to make it right.
I especially like the hexagonal handles that also curve over the length of the handle. But it just seemed a little too complicated.

Very cool! What is a compression nut? Is that just a regular brass nut I can get from the plumbing department?
