The nest step is to make some 3/8" half round molding.

Before I install the half round bead there is one more step that I have to do. Stay Tuned!

I use a lot of drilling jigs around the shop and especially out on the job sites installing hardware. This is how I make dead accurate jigs that will last a long time.

I start out with some ½” Baltic birch.

The key is to use a ¼” brad point bit and a #3 Vix bit.

I lay out my holes very precisely.

Now to the Shopsmith outfitted with the brad point bit.

I have attached a guide block and these jigs are ready for use.

First step is to place the jig center on the work piece.

Now drill through the ¼” hole with the Vix bit in a hand drill.

This leaves 2 guide holes.

Now back to the Shopsmith fitted with a standard 3/16” bit. On the job site I would do this step with a hand drill.

Done and ready for the pull. I have also jumped ahead with the glue. Back to that in a bit.

By using the Vix bit the jig does not wear and the hole spacing stay consistent.

Nice work Mark - as usual. I like the drilling jig tip. Can't wait to see your magic applied to the barrel.

I have been planing to build this jig for some time. Now seem like a good time.

We'll let the glue dry on this stop block for a while.

Notice the center of the jig is not in alignment with the blade.

Now I just slide the jig and work piece along the miter slot into the blade.

Now the center of the jig is in alignment with the blade.

This is where the stop block come into play.

Now just slowly rotate the work piece into the blade.

This is the view from the back side when the cut is completed.

It is easy enough to just break away the scrap.

One perfect circle.

Well almost! There is no such thing as perfect!


I have used many circle cutting jigs in the past and most designed for the band saw require you to start with an square the exact size of the circle. It usually ends up with a few flat spots and or a band saw blade pushed to the side and therefore not tracking and cutting properly. I am very pleased with this jig. It may actually be a perfect circle!

The "round" features the customer spec'ed are kind of neat. Looks like the interior of the Hobbit's house ....

Really cool work!
