Need help with jig design

[Tim Boger]

Hey Guys,

My preference is Segmented Turning and I have been looking around for ideas to build a table saw jig to help me cut the 15 degree star points (pic)

I have an Incra 5000 that works great for the regular segments but I figured there must me something more specific to help with the type of angles I need here, their also kind of small pieces at around 2" x 3/4" 12 Point Star.jpg

If you have a picture or a link to something you think will help me I'd sure appreciate it.

Thanks,
Tim

Have a look at this site. They have videos and plans for a segment sled.

Here are three possibilities that I would try if I had a lot of these to do, both would require experimentation.
1) make a jig the will cut twelve segments to make a ring. In your drawing the diagonals would be the center of the segment that I am envision. When happy with the fit, then make a jig that back cuts from center of the outside edge to middle of segment leg. Reverse to cut the other side. This again will require experiment to get it perfect.
2) cut 24 segments and cut from a corner of outside to middle of opposite side.
3) cut to triangles(segments) and glue ends -- might be easy -- glue up tricky.

Good luck
Bob

Hey Bob,

I'll be printing out your ideas and working with them this weekend, thank you for your suggestions.
