DualSaw?

[Mike Jackson]

Hi all,
I watched a little of an infomercial today for a DualSaw (www.dualsaw.com)

I had just cut a couple of interior straight lines in some MDO a couple of days ago and was wishing for a small circular saw. So, this tool caught my attention.

Has anyone bought one of these tools, or tried one out? If it worked like the commercial shows, it'd easily be worth around $225 delivered.

I understand the logic with the dual rotating blades and going forward
and backward. The one thing I can't quite warm up to is going into
ferrous metal, rebar etc. Has anyone ever put a carbide blade into
steel before? Scared me.

Hi Mike and Mark,
What is MDO?
As for the carbide wheel, cut against the rotation and start slow so it can heat the metal a little first. It can kind of melt its way through the cut.

PS The first thing my machine shop teacher told me was, "Everything you can do with those machines you can do by hand." Then he showed us the chisels and files!

David,
MDO stands for Medium Density Overlayed Plywood. The top layer of the plywood is replaced with a smoother fiber board layer which accepts paint well and has no knots or grain. One brand of it is called Duraply, but I haven't seen people use that term in a long time.

"Everything you can do with those machines you can do by hand."

Hmmmmm....that's a slippery slope concept....but I think you need to add "eventually" at the end of it. As the years go by, the biggest cost of any project is the labor that goes into it, so the goal changes to using the labor most effeciently using the right tools you can buy once and use over and over.

Back to the saw, if their claims are accurate, you aren't supposed to have to change blades to cut all those materials, including cutting across a nail while sawing through wood. The commercial has the flavor of those Ghinsu Knives and the Ronco Slice-O-Dice-O-Matic tools, so it makes you wonder how they really perform in the field. That's why I made the post.

I just did a google search for dualsaw reviews and found this:

Sounds like most of them think it is a piece of junk.

For what I was doing, this saw might be the best tool:

For cutting metal, this might be better:

I don't like the fact that it doesn't have a flat bed like a regular circular saw. Seems like it would hard to cut a clean straight verticle line

Hi Mike,
The duel saw is impressive on the site! with wood I think you would not have a problem with it. Seems like the teeth might clog up after a while though.
That aside, for the slot shown, I would try a small diameter router bit. Clamp a piece of wood as a guide and that would make a nice straight cut. Or, if you drill a small hole at the head of each line you can use a coping saw. That would probably give a narrower slit.
That reminds me... I have seen a Sherline lathe that was set up as a mini table saw. A machinist slitting saw was mounted on an arbor with a home-made aluminum table on the top of the head. Slitting saws are very thin so they don't create much friction therefor better control.
Proxxon is really popular here in Japan. http://www.proxxon.com/us/ The longneck angle grinder with a slitting saw on it might work well. The Proxxon site lists slitting saws as Spring steel cutting blades.
Just trying to be helpful...
