Topic tags/keywords: question

I have a 10 inch dewalt radial arm saw. I saw on the New Yankee Workshop, Norm was making 1/2 lap joints using a dado set. The dado set had two blades, some how the blades touch then 180 deg they could be opened up to 3/4.
I have search the web and even e-mail the NYW to get more information on this dado set. No luck.
The response from the N.Y.W. Was to send me to a site, but this site didn’t offer it.
Ther has to be some devise between the the blades that adjust the width of dado cut.
To see this go to you tube new Yankee work shop he is building a shop work bench.
Has anyone see or heard of a dado like this? I am interested in finding one!
Thanks any help appreciate
Mike

That was one of the very early episodes, I suspect that dado set isn’t marketed anymore….at least I haven’t seen it anywhere. Any of the sets (except one) that wobble got a bad reputation for not cutting perfectly flat bottoms, but most of those were a single blade set up. The one Norm had may well cut flat bottoms, but what would be the advantage over choosing a stacked set? In any case, you might find a second hand one on e bay. but I haven’t seen a new set like that available. BTW, your Dewalt will handle the stacked dado just fine, I do it all the time on mine.

If it’s the episode where Norm is making the wood working bench, early in the series. Then it’s an adjustable dado blade. I have one that my dad had in the late 60’s, it never made it out of the package. I read that they aren’t the greatest dado device ever made.
Just Google adjustable dado blade and you’ll find many to chose from.

Thanks Fred
I was afraid of that. The reason I wanted one is I use pallet wood and most of the wood veries in thickness
And I hope that that dado could be adjusted very fine!
I don’t know how to e-mail a reply to you. ( very new to LJ & computer dumb)
Thanks

Is it a two blade? I don’t want a one blade.
I saw all the single blades on google.
Thanks

I believe you are inquiring about what was called a “Wobble Dado”. I remember them being made by Sears back in the 60s and 70s, but have not seen or heard about them for some time. Not only were they very sloppy but they created excessive vibration, ergo. “Wobble”. I seem to recall buying one but gave it away after one use. My advice is to forget it and go for a quality stack dado set. By the way, The Tool Nut has the best price I’ve ever seen on Forrest dados, which are top of the line IMHO, c.f. http://www.toolnut.com/SearchResults.asp?Search=Forrest+dado

This article may change your mind about getting one of those blades and using it for half lap joints.

I used a stack head dado blade all the time on my RAS. It leaves a nice flat bottom where the adjustable ones leave a curved bottom.

The stacked sets come with shims that allow you to fine tune the width of the dado to just about anything you want, down to .001”. Of course within the max width of the set, which is normally somewhere around 13/16”. There is another possibility, the Freud SD608. It’s sortof a combo between a stacked set and a wobble. The stacking gets you close, and then dial the wobble for the fine adjustments. Those who have them (and I’m not one) claim it is a very good dado set. This is the set I alluded too earlier (the “except one” part) and forgot to go back and explain.

I have an old Craftsman Excalibur double wobble blade that works ok for stuff that doesn’t require a great deal of precision as it’s tricky to fine tune. For most of my dado work I use a stacked dado set by Freud. Freud does make an adjustable dado set that’s supposed to be easier to fine tune and offers flat bottomed cuts, it’s just not cheap: http://www.rockler.com/freud-sd608-8-dial-a-width-dado?utm_source=google&utm_medium=cpc&utm_term=&utm_content=pla&utm_campaign=PL&sid=V9146&gclid=CNWU3s2O2sMCFUojgQodGxIAjA

I think I have one new in the package I bought back in the early 90s. When you think about it a large unbalanced rotational mass is probably not the best thing for a saws bearings.

You will never guess what I tried.
I took a 3 inch hard rubber car body to frame rubber bushing mount.
I ground it into a wedge full thickness at the top and about 1/8” at 180 deg.
I took two identical 10” blades. And mounted them on the arbor with the wedge in between
It cuts 5/8” each pass! I don’t know how safe it is but I am very carful of it.
It is curved at the bottom, so I’ll has to use a chisel to clean the dados up.
I have only made test cuts so far.
I have not started a project yet but plan to
