Ok, so how would you go about making a set of jaws for a
three jaw scroll chuck? Can you do it without the use of a
computer?

I've made several sets of soft jaws for my two scroll chucks that were made
before reversible jaws were made separately from the scroll.

The first job is determining the shape of a tooth. Use an edge finder and
DRO to get three representative points on each side of the tooth. These
three points determine a circle, use a CAD program or a circle calculator to
find the radius, center and arc end points.

From here I wrote a CNC program to cut scroll teeth. You could do the same
thing with a rotary table.

I licensed a copy of Alibre, for chits and grins, I've been modeling the ball turning
attachment I saw at Names this year and was published in 'Home Shop Machinist'.

I'm pretty well convinced I'll be able to make it faster than I'm drawing it. ;)

Tomorrow I'm going to try to get the insulation installed in the 11' x 8' soon to be
heated room out in the garage that has my lathe and bridgeport in. Winter is coming soon.

Had to work today :(

Ive got 3 scroll saws. 2 of them are 26" between the blade and inside of
the scroll..the other is 36" to the back of the frame.

How do I fix the blade holders?
