I have a new 10" Grizzly G0691 table saw scheduled for delivery this Monday. Probably should find a table saw forum for questions on that but I've gotten such helpful answers pertaining to anything wood related on RouterForums I hate to look elsewhere for advice.
I recently found buried in my garage full of treasures, (which my wife calls other names that she will have to deal with upon my death), a Craftsman 7" Kromedge Thin Rim-Satin Cut Dado Set. Cat. # 9-3257. I have no recollection of ever buying it or using it. It appears to be brand new, never used.
My question is two fold:
1. Can I use the 7" safely in my new 10" table saw.
2. If so, is there a manual available for it? Never used such a blade set. Only slight experience with a wobble dado blade.
On number 1. Yes, to the spec's your saw says it can. Meaning Grizzly says you can use a dado up to a 13/16" wide and 8" in diameter. What they didn't say, which is assumed... Is that you need to use a dado insert with it. that might be something you will want order or make.
Stacked dado's are fairly straight forward. Figure out how wide a dado you need. Always use the outside blades. Between them use chippers to add width. Use shims to adjust in more width to bring it into fine tuning of what you need. For instance, 2 outside blade (1/8" each), 2 1/8" chippers, a 1/16" chipper and a 0.005" shim equals 0.5675". Why the in-betweens? 3/4" plywood is smaller than 0.75".
So order goes dado blades, with chippers sandwiched between them, with shims spread out between the blades and chippers. Don't put the shims all together, rather spread them out. I turn the blades and chippers so the teeth are rotated spread out between- sort of like blade, chipper with teeth not touching each other,next chipper turned about 30 degrees or such... and on.
That may sound anal. But I figure it evens out the cut... and carbide teeth are brittle. I don't want the carbide teeth touching each other. They also don't dull as fast that way.
