« Part 2: THE Jig and how you too can make one. Part 3 of Spirals series Part 4: Assembling the jig »

The base is just 1/4 inch ply. any size is ok..I have a cirlce cutting jig [ a jig makes it easier]..see circle cutting blog Drill a hole in the ply to use as pivot point

The distance from the centre of the pivot to the blade is 9.5 inches Set this distance and cut an arc across the end of the ply.
The fence is made by making one cut at the same 9.5” distance and then drilling another hole back an inch or so.[don’t move the jig!]. not really exact but enough to be able to drill some holes in the fence…and making a second cut.
Using the very important template set the fence and mark the front this will be your guide to fine tuning if needed.(I didn’t need to fine tune , cut exact first go… lucky.)

I made the Bridge Clamps by gluing up some purpleheart..for strength.
I sanded the clamps and oiled them to make them pretty and attached a small piece of cork to the foot that in in contact with the timber..

Ok, I’m beginning to see the light. I am still finding it hard to believe the possibility of getting a perfect glue line straight off the bandsaw, but I have faith in you Larry, and so will try it out. The problem is that now I want to drop my ongoing projects to do this exciting and wonderful thing. Have you no pity? Check your blog no. 1 on this project for my clamping suggestion.

stefang ; i think the carter bandsaw guides make a difference to a smooth cut ,
how ever a little woble in the cut will fit the woble in the next cut .
we’re hooked larry !

David, I’m just lucky to have guides in my bandsaw at all, never mind those good (read expensive) ones for pros. I think I will go with the matching wobbles instead, which is more in line with my usual experiences with machines.

I can’t believe anyone would use purple heart for a jig.
Just kidding, it looks great—-The jig and the project.

Kent,.. and this from a man who makes jigs with figured flame curly maple, bubinga and walnut..
I only used the PH for its strength and durability,

understand the parts and how they go together, however do not know how to make the ‘template’
certainly a critical component. understand that both arcs are 9.5 degree radius, but would like some
help in constructing the template, maybe some cord measurements?
