Lipless how to

[numbskull]

So here is how I cut it.
You need 2 jigs.
The first is to cut the angled arc.
It needs a base you will clamp to the drill table (which has been tilted-I used 20 degrees) and a sled that indexes with the base to swing the plug past the sanding drum.

I used the weight hole to index the plug.
I used a pin block to keep it straight and centered in the tail hole (if you left a square end you don't need this)
The circular block near the front is a cam meant to limit side motion from the sanding drum friction (it worked poorly).

I cut a matching circle/arc but this was a mistake. Better to use a can lid of the right diameter and two contact points on the sled (1/2" sticks with angled ends screwed equidistant from the center line on the bottom of the sled would work).

If you look at the base plate on the drill table you will see it has two sticks on it. These are centered and spaced the diameter of the sanding disc so I can use them to center the base plate to the drum above it.
