Some of you might remember when I made a drawer pull using the drill press. I got the idea from an article published by Fine Woodoworking Magazine. I thought that it might be possible to extend the idea to rasp handles, but the added length could present a few problems. Because the rasp handle is considerably longer than a drawer pull, and would add to the force exerted by the rasp, I thought that this would need to be circumvented. I came up with the idea of using a sharpened threaded rod as a drive center. When using this method, I make sure to keep the bottom of the spinning blank from contacting the wooden platform which holds the drive center. This seemed to do the trick nicely and has opened up the drill press-rasp/lathe method to new potential.

I have a few rasps that were in need of handles. If I owned a lathe I would have quickly turned a few handles, but unfortunately I do not. I had really good luck turning drawer pulls at the drill press using a few rasps, so I thought I could use the same process to make a few handles. Because the handles are longer than the drawer pulls that I made in the past, I had to modify the process a little. I used my grinder to make a metal point for the wood to turn on at the bottom of the drill press; which should alleviate the extra force caused by the rasp. The process worked really well.
I hammered (wooden mallet) the rasp into a pre-drilled hole in the handle and unfortunately the handle cracked slightly. I wrapped the cracked region tightly with electrical tape and this seemed to work ok. When I make a second one, which I plan on filming, I will use a metal ferrule to prevent cracking; which I should have done the first time. It’s all a learning process.
The idea for this mortiser add-on has been running through my head for a few weeks now. I wasn’t sure how well it would work and I couldn’t resist trying out the idea any longer.
The templates are secured by the two bolts pictured above. An aluminum stylus rides against the template as the mortiser is moved forward and back. So far I am pleased with the results and I can see several practical uses for this add-on. The add-on will not get in the way when I need to use it for a standard mortiser. Yippeee!
