Question Hi guys... I'm back

Been away for a while, suffered a stroke and could not do much at all until the last month. So I've just been reading things and not replying.

However, I'm mostly better now and ready to head out to the shop and do something besides watch the tools rust.

I got a question for anyone who knows how. I have one of those older craftsman flex drive TS. and do not have the original insert that came with it. I've made a few ZCI's for it that work just fine when cutting at the 90, but I'm wanting to make some for a couple of different angles.

Is the process the same as making one for a straight on cut or should I do anything differently to cut the angled slot?

If Woodworking is so much fun why isn't it called WoodFUNNING?

I've made a few videos

Yeah it's a little different

Welcome back!
You won't be able to drop your 10" blade down far enough to start it at a 45 degree angle ...so use a circ saw blade like 7 1/4 or a dado blade say 8", and then raise it up for the new angle.
Or you can route out the slot to a thinner section right over the blade and use your 10" blade. Just don't go all the way through!

The answer to your question will only be as detailed and specific as the question is detailed and specific. Good questions also include a sketch or a photo that illustrates your issue. (:< D)

I have two, one for 45 deg, and one for 22Ĺ deg. The problem is that whatever angle you make it for, will dedicate it for that angle. Slight movements, like raising and lowering the blade can make it larger, or changing the blade.

May be a dumb dumb but what is a flex drive TS. I am not understanding the equipment or the issue.

Someone, an engineer or tool designer came up with the bright idea of eliminating the drive belt on the table saw and replacing it with a cable housed in a flexible covering to drive the saw arbor.
Like so many things it sounded good in theory, but the operational life of them and some quality issues limited their usefulness. Belts are still driving the most expensive and high quality table saw today. The flex drives are no longer available if I recall, and they were expensive as replacement parts. No so with belts.
A net search will get you more info if you are curious:

The insert being dedicated to a particular angle doesn't bother me. I'm not sure how you could make a non-dedicated ZCI. I've already made two different ones for different types of 90 degree cuts ( one with a splitter for through cuts and one without for cutting tenons and/or dados ). What I'm concerned about is the process of making them. Seems to me as though if I just raise the blade into a blank like I do for a 90, the area in the middle of the blade after the teeth pass through would bind as the blade goes higher. Maybe I'll just make an insert that has the same opening as the insert that is supposed to be installed on the saw and not worry about the tear out.

On a different note:

A flex drive TS is a Craftsman saw that was produced in the late 80's. If you can remember the speedometer cables in older cars that had a cable inside of an outer casing that is how this works, except the cable housing is close to 3/4 inch in diameter. It takes longer for the blade to come up to speed and you have to be very careful so that you do not cause the blade to bind in the cut, but it has worked well for my needs for a very long while. The cost of a replacement saw is very far out of reach right now and even a used belt drive in good condition is out of my price range. Being somewhat handicapped and unable to ever drive a commercial truck again, I'm only living on disability which pays every month less than I am used to earning every week!

New cables are still available from Sears for $90.00, but other replacement parts are very scarce. Its not possible to get the original insert, however dado inserts are available for both the Sears 7 and 8 inch dado sets and the old molding head cutter.

If Woodworking is so much fun why isn't it called WoodFUNNING?
