End drilling dowels, how to, with photos!

Hello,

Here's a great way to get centered holes in the end of wooden dowels. I can't take credit for the idea, John and Michael have shared this with me, and it worked great. So I took some pictures to share with everyone else!

The first step is to put your dowel into the size bushing that it fits.

The second step is to clamp this bushing into the DJ-1, it should be slightly lower than the set screw and clamped in the jaws.

The next step is to install the bushing that you will be drilling with so that it sits on top of the bushing with the dowel, and secure with the set screw. Then drill the hole.

The result! a hole in the center of the dowel.

As you drill out the center of the dowel, it may want to spin or be pushed out of the bushing. I have found that I can hold the dowel from below while drilling to stop that.

Shame on me, just saw this post.

The reason this is the recommended way to center drill dowels is because they are typically not round.

In our experience, this puts the hole dead smack in the center and as a wood clock movement maker, it is as accurate as center drilling on a wood lathe on hole depths up to 2-3X the dia.
