I have some delay on a current project due to a tool repair. No worries, there is still plenty to be done. I am planning on some round table tops for this and a couple future pieces and so wanted to further refine my BS circle jig.
I took a piece of poor quality scrap ply and laminated a piece of scrap luan to it to get the thickness I was after. I used a dado stack in the tablesaw to cut a groove to accept a piece of t-slot miter track.
The track and the mating bar come from Peachtree. I cut short sections of the t-bar and tapped them for 1/4-20. I counterbore a couple holes in the plywood to loosely fit bolts with washers and then put 5/16" through holes to allow for some adjustment.
The t-bars slide into the bandsaw's t-miter slot and I snug down the bolts.
The rear is supported on a roller stand held by a simple pair of cleats.
Another piece of the t-bar is tapped to accept 1/4-20 x 3/8" long allen head set screws. These can lock the pivot for 6" to 6' diameter circles. Two other holes are in this t-bar to accept a 10-24 screw or a 1/4-20 from underneath to act as a pivot pin.
She cuts like this.
Now I just need to drill a hole in it to hang it on a peg . . . . somewhere . . . .
