Topic tags/keywords: dado stack question

Any recommendations, and do I have to pay close to $100 for a set that doesn’t leave nasty ridges at the bottom of the groove? (The vintage Craftsman ones included with my CL table saw have that problem.)

I’m not an industrial facility, just a guy using this once in a while, mostly for plywood and softwood.

TIA

(Sorry if this is redundant – I searched the site and came up with nothing that says “dado!”)

You can use a dado clean-out router bit. It
will compensate for dado depth variation due
to panels being out of flat too. Usually the
bit isn’t removing much material so it just
takes a few seconds to clean up each dado.

I had mine re ground to produce flawlessly flat bottoms without bat ears. It takes a well equipped and knowledgeable sharpener to do the job. It ain’t cheap.

I have this set from Oshlun. Very satisfied and less than $100 bucks.

For standard cuts like dados and rabbets in plywood, a Freud Diablo will work just fine.
I use an Infinity Dadonator for hardwood joinery because it has 8-tooth chippers. Feed rate is a little slower with the Dadonator, but it will usually cut splinter-free tenons in hardwood.

I still have my Diablo dado stack, but I haven’t liked it much since it came back from the sharpener. They didn’t get the chippers all the same diameter, so it leaves ridges now. However from the factory they make pretty nice dados. Before you balk at a hundred dollar price tag, remember you are buying 6 or 7 tablesaw blades with each dado purchase.

All dado sets will leave tiny “bat ears” at the corners, but that shouldn’t matter with plywood joinery. You’ll never notice them once the joint is glued up.

Okay, thanks very miuch for the replies and recommendations.

The regular 10” blades on my table and compound miter saws are Freud Diablo, and I’m happy with them. That was my first thought, but I was wondering whether ones that cost 2/3 the price on eBay are as good. The Freud and Oshlun are around the same price (about $100) – which I’m not balking at, I’m just asking!

I think sharpening a vintage Craftsman dado stack – which looks like it’s from the ‘50s – is a spectacularly poor investment, whether it’s done by a professional sharpener or I make a mess of it myself fooling around with a router bit that costs as much as the sharpener. :) Better to get a new one.

pintodeluxe, tiny bat ears are fine. What I get now looks like someone took a garden rake to the joint!

So Oshun or Freud Diablo it is.

Oh, I have another question:

Will I be happier with an 8” stack than a 6” one? Does it just let you cut deeper dados?

(It’s a standard 10” table saw, so it can accommodate either.)

Get the 8” version. It lets you cut offset tenons with ease.

Don’t forget about the proper throat plate. Did your saw come with a dado throat plate? Is there one available for purchase (oem or aftermarket), or will you need to manufacture your own? Also, check to see how wide your saw can actually handle safely, both in terms of arbor length and horse power. Wide and deep dado cuts can easily bog down the motor. Should say in the manual also.

+1 for the Oshlun set. I’m definitely no industrial facility either, but I enjoy mine. Though my saw can only handle up to 3/4”, not the full 29/32 the Oshlun is capable of.

Yeah, I have the throat plate – which is a good thing, because it’s a Craftsman with a weird throat (and also T-shaped nonstandard tracks). I don’t think it accommodates 3/4”, but it’s big enough.

And thanks Pinto.

The best set I’ve use so far is the Infinity Dadonator by a pretty fair margin….its just a great dado stack.

The best bang for the buck IMO is the Delta/DeWalt 7670 for ~ $120…gives a taste of the better sets for about half the price, has great shim stock, and a great carrying case. The really cheap sets just aren’t worth buying IMO.

6” dado will have less mass, therefore easier on the arbor. Just saying.

8”. Take a look at the economy Freud version. Lots of carbide you’ll get many sharpenings out of it.

If you want something on a budget check out the Oshlun sets, they get pretty good reviews for the price. Here’s a link to the six inch set, for $70 it seems like it would be worth the price.
