Drill two holes in the fence . one a little larger.. to take 1/4 ” bolts . Mark these positions on the base and drill these holes to attach the fence to the base. One bolt is held with a nut and other with a Knob.[for adjustment in fine tuning the fence if necessary].
Drill two addition holes in the fence to accept 1/4 ” bolts for tightening the bridge clamps.[These holes got through the fence only] Refer to the photo.
In his pic you may see that I inserted a bearing to serve as a bushing so that the hole would not wear with the amount of use it will be seeing.[the jig pivots on the bolt in the circle cutting jig..
A few different angles.
If you don’t get a good fit on all twelve pieces you can undo the knob at the back and adjust the fence in or out
Thats about It not really much to it at all

The thing I still can’t understand is the template. Am I right in thinking that the width of the template determines the width of the pieces to be cut?

Thanks for this post. You gave my a great idea for assembling my gear blanks with spiral shapes vs the straight pie cuts I’ve been using. Thanks for the post. I’ll let you know how the gear blanks work in my new clock designs! Of course, you get all the credit. Max

Everybody seems onboard with this last blog while I’m still on the quay. Anything besides a NO Larry? Like what does the width of the template determine?

Ok, I finally got it. But the template does determine the the shape of the segment including the width. Am I not right?

Mike you got it …it’s not about the width per se but the shape of the template. The width does determine the number of pieces in the finished circle but the shape is all you need.
BTW Mike didn’t mean to be rude just trying to get you to work it out and you were on the right track.

A little secret.
The arcs on the template are just segments of the circle with a 9.5 inch radius.. You work out the width for the number of pieces in the circle.

If I say I understand all of it do you think I’m smart or lying?
Nice work Larry.
