Is there some reason to not put a normal insert in the table, mount the rip fence and position it so as to space the ZCI over the same blade it is to be used with. and reposition the insert(front to rear) so that the blade will extend the cut as the table is lowered? Clamping it down would be a good idea!;)

You are absolutely correct, Charlese but that would be no fun at all. Besides, I did not spend good money on my Shopsmith so that I could use one of Grandpa's hand saws.

Dusty,

Yeah, I use the upper guard. Once I have cut the insert by lowering onto the SS saw blade I extend the rear opening with a fine blade on my Bosch saber saw. On other inserts I have installed a kerf splitter in the insert to allow for situations when I can't use the saw guard.

This would be an excellent solution and if I am lucky the finished sled will have miter bars with the t-slot feature built in. I have a miter bar project on a wait list (time available) with a friend who is a machinist.

I want to thank all who have commented on this project. I have a sketch done and it will be on the bench in a couple days. I should be able to finish it in a couple hours (mostly thinking time). IF the concept is valid.

I will post results whether it works or not.

Double sided tape??

I like hand tools but my batteries do run down...

Those are thing that make good.

Y'all are making this way too complicated IMHO!

FGS all you need to do is extend the back end of the kerf!

A sled. Anti tip washers. A mount for the blank. Runners for the sled.

What is wrong with the fence set to the 'correct' distance from the blade(so it matches the kerf first cut), positioning the insert towards the front of the table,(all this after putting a 'regular' blade insert back in the table), clamping the new insert so it stays flush with the table and fence, and finally again lowering the table to extend the first cut?


Or do I mis-understand the 'objective'???

I think you do. You're thinking the objective is to extend the kerf on the insert. But the real objective is to spend time in the shop to build a new gadget/jig that is clever, functional, and safe. The objective is the build... not the kerf.
