Here is my first go around at making Drawbore Pins, I used some left over Red Oak I had, glued up two pieces and then hand sawed and planed the blank down to the recommended size and drilled the hole for the drift pin. Unfortunately I didn’t have the exact size bit called out for in the plans, so I tried to ream out the hole some. I then chamfered down the sides and sloped the handle toward the pin using my hand planes. Everything was going slowly but well until I seated the handle onto the drift pin with the last few mallet blows and yup, you guessed it, the handle split due to the hole size being just a tad bit to small, bummer for me :o(
So it’s off to the store tomorrow and pick up the correct size drill bit and start over, good thing I glued up more than one blank! :o)

I am embarrassed to say that I didn’t know what a drawbore pin was, but thanks to google I now know, and I am looking forward to giving it a shot- anything that can help my mortise and tenons out is welcome. Thanks for sharing!
(If there is anyone else that would like to know more Christopher Schwarz did an article about these in the woodworking magazine, and it can be found here)

Thanks guys for the posts and the link.
I used to strengthen M&T joints using this method (as my dad awlays did), but I did not know the term.

Mike Lingenfelter had the same problem as you.
Maybe you should put a metal ferule on the handle, for strength.

Yes one of mine cracked too, but one of my drift pins had a slight bend in it which caused it to track. The other one came out fine. I used it on my workbench and it worked great! Which reminds me I need to go back and finish the that broke!

Chris, yes that is the same aricle I am using to build mine.
Dick, the wood is split to badly for trying to fix with a metal ferrule, but a good idea anyway. If I had followed the directions properly I am sure it wouldn’t have split the wood and hopefully won’t be needed. I think it was just a case of trying to fit a square peg into to small of a round hole.
Mike, just want to say thanks to you and Dick, Dick for posting your link and you for showing that great idea of wedging the handle in the vise to work the chamfers. I had a heck of time with those last night, but now with your idea, it should go very easy on the next two handles, thanks again.
I picked up the smaller drill bit today (13/32) and getting the larger one (17/32) is arriving tomorrow. I will have to do a better job of setting up the blank for drilling to make sure it is straighter. The bit in the handle now is on there very hard and will have to be chiseled off, so I think by using the proper drill bit and drilling down straighter, it should all work out fine, will hopefully post pics this weekend of two completed tools :o)

Pat, just a thought. Could you drill the hole in a block first before you shape it to size. That might overcome the problem of the tearout.

Grumpy, thanks for the recommendation, but if I had just used the proper drill bit size the handle would not have split, the drill bit I used was way to small. I just posted a small drawbore pin I finished today and I had no problems when I used the correct sized drill bit. I picked up the bigger drill bit (17/32) this morning and will be reworking this tool tomorrow if time permits.

Experience has no substitute. I am sure you will not make the same mistake again. Thank you Chris for the reference to woodworking magazine. It is full of good information.
