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.
