Zero Clearance Table Insert

Page 1 of 2  
I have an older Craftsman table saw and I want to make some zer
clearance table inserts out of some 1/4" MDF. The problem I have i that the top of the 10" blade is almost even with the top of the table How does one get to install the insert without killing himself

Got an 8" dado stack? If so, use one of the 8" blades, not a chipper, to make the initial cut.
You can also route out enough clearance for the 10" blade with a router if need be.

If you don't have an 8" dado set, a 7-1/4" circular-saw blade would do the job as well.

That's really the easiest, especially if you have a router table.

I too have an older Craftsman TS. What I did to cut the zero clearance inserts was to install a 8" blade on the saw, then raise it to cut the slot. I then re-installed the 10" blade and finished the cut. Hope this helps.

9" saws as well.
I don't know how old my Craftsman is, but it does have a repulsion induction motor which was discontinued in 1953. I mention this fact because there is ample room between the top of a 10" blade and the saw table.
And, my saw will only accept a 1/8" insert.

I'd check out what you can BUY, first..
I just bought 2 for my Ridgid/Craftsman TS for about $20 or $25 each from Lee Valley... Ok, they lied to me about them fitting my say, but I got them to work.. *g*
Even if you make your own, check out the pictures of the factory made ones.. For one thing, you'll notice that they come as "left or right" cut... Why? They have the slot started for you, so that you can install it over the lowered blade and then raise the blade...

I'll bet I can crank out 10-12 of them in the amount of time it took to get yours to work! <G>

The first one takes all the time, the rest of the stack takes just a few minutes. I've got 'em made for common bevel cuts, different dado widths, etc... Some even have glued-in splitters.
Weird plate thickness? Rout a rabbet all the way around the bottom edge, to set the insert slightly below the surface, and bring it back up with leveling set screws.
As Swingman said, use a single dado end blade to make the initial cut, if necessary. They're not furniture, no need to get fancy, just whip 'em out.

You probably could, Barry... because you're done them before and know what you're doing... You probably have a source for hi-tech slippy-slidy material for it near you..
I wanted it NOW for a new TS and didn't want to design and make one with whatever materials I found lying out in the desert... I'm learning the TS to improve my turning... I really don't want to take time off from turning to reinvent the wheel to save a few bucks..
I needed 2.. zero tolerance, which I could probably live without, and dado, which I figured might save a finger someday... If I ever need one for a bevel cut, after I learn what that is and if I have a need for it, I'll decide to build one..
Though I also love building jigs and stuff, I'm not interested enough in the saw to build one to save $40...

Cool.. I can get plywood in Mexicali.. Only 3 hours away.. It would/wood only cost about 15 gallons of gas and half a day to save a few bucks by making my own..

Sort of a "sore" topic...
Everyone told me about all the ironwood and mesquite "laying around the desert"....
We almost bought a desert rail to go get some... real rational thinking, spend 8 or 10 thousand bucks to go find a few bucks in wood.. lol
Went on 3 "scouting" trips with the local 4x4 club here and didn't find ANYTHING usable..
Being in the middle of a huge desert reserve, you can only take down wood, and what little there was on the ground was old, termite munched, rotted and a great home for scorpions and rattlesnakes...
We're going to Yuma soon for a shopping trip... She goes to wally world, etc... I go to Lowes and harbor freight...
I've found that the best way to smuggle lumber across the border is to bury it in groceries.. lol

last 7 years. Which Wally World? There's 3 of them now. The original on Pacific Ave. The 2nd on Ave B and 28thStreet and I believe they just finished the new one out in the Foothills. And Harbor Freight is on 16th St. and about Arizona But I can't remember for the life of me where Lowes in located at!

I'm pretty sure that Yuma has one, but I think that we go to Lowes when we're in El Centro and Home Depot when in Yuma... Easier because it's close to Sears, Harbor Freight and the stores my wife goes to after she drops me at HF.. lol
She goes to a "super walmart" on the main drag... senior moment prevents me from remembering the street name, but it's across the street from a Von's...
We used to go to Calexico/El Centro to shop until we tried Yuma... Just about an hour farther from San Felipe but cleaner, nicer and better stores.. (no duty free though)
