Thread: Dual blade saw, anyone used one?

Tweet

I usually don't bite on those TV infomercials, but I just saw one that caught my attention. It is for this saw:

http://www.dualsaw.com/

The part that I was interested in was where they cut a car in half with it, and it didn't seem to take much effort. I am going to be starting on my rpu project in the next week or so and I have been trying to figure a good way to take about a 3 foot x 1 inch pie shaped slice out of the 2 x 4 x 3/16 tubing for the frame. I want to taper it from 4 inches to 3 inches for the front, and my choices were our plasma cutter, the bandsaw, or a cutoff wheel. This dual blade saw looks like I can put a straight edge clamped to the tubing and make a pretty straight cut.

Has anyone used this exact saw? I think my Son Dan bought a similar product from Sears a while back and had to return it because it didn't do the things he thought it would, but I hope this one is different. I should have it in a week or so and will post my findings when I try it out.

BTW, it was on sale for $ 199.00 and replacement blades are $ 39.00 a set.

Don---I bought the same saw from Menards for a lot less than that--

I got it because it had the narrowest amount of stuff on the side and I used it to cut up some subflooring as close to the wall as I could get in a house--does a super job of that and doesn't throw the dust around too bad

I haven't used it to cut any steel but it does have a way to feed wax to the blades for lube---I also think it would only cut thin stuff

I think that in your frame, I would use a saw-all or the plasma--portable Milwaukee band saw would work nice also

But I wouldn't pay $200 for a saw just to cut some steel that I already had tools to do it with

Holy cow - Billy Mays is back from the dead after18 months. I just saw him screaming at me on the attached commercial - http://www.dualsaw.com/howitworks.html.

Can you just buy a blade? It looks like something that will fit an angle grinder with a 1/2 - 5/8 arbor. Why not check Harbor Freight as well.

Me. I would just do the cut off wheel routine since a pack of 10 wheels are only a few bucks

I bought one from Sears and it does just what I thought it should. I cut some 3/16" frame rails and some round tubing of about the same wall thickness and it went through that real easily. One thing that's important to remember is it takes out a good 1/8" material at the cutline. It does throw some chunks around, however.

throws chunks around---yep you need to wear safty GOGGLES

I watched the pitch and the thing has dual blades spinning in opposite directions, one CW and one CCW so it's not just the blade(s). Like wingman9 says it is going to take a kerf - I'm surprised it's able to keep it to 1/8". May be a neat tool, but not sure it's the right one for your pie-cut.

Yeah, the blades spin in opposite directions, so it kinda nibbles the material you are cutting. From the cuts it made on the car they were cutting up it loooked pretty straight. One good thing is I have 30 days to return it if it doesn't do the job I need it for.

I could use the plasma cutter, but I hate that thing. I keep burning the tops of my feet when sparks go down my shoes. And the bandsaw will tend to cut the two walls of the tubing differently. As for a sawzall, I am really dangerous with one of those. So this looked like a good alternative.

Glad to see some of you have one and that it isn't a total piece of crap.

another economical means is to get abrasive cut off type wheel and put on a skill saw--

Wow you can use it to chop veggies too! Just have to replace the cutting board!
Actually that looks really cool Don. I wish I had one for all the sheet metal I cut last year. It's seems that because of it's shape and size that you would be able to do very precission cuts. Worth the cost for the savings in time and mistakes. I agree about the sawall too! If they bind up...yikes!

I've done that in the past and it works pretty well. If this dual blade thing doesn't work out I may go that route, Jerry.

Steve, that is what I liked about it, the size seems easy to control. On the TV commercial they were even cutting about 1/2 inch drill bits in half. I know TV stuff is edited, but it looked fairly convincing.

We'll see. Worst comes to worst I can cut cars in half with it.

Don

I have used a rotozip to cut metal. Not precision cuts but gets the job done pretty good if you pay attention.

so you are actually going to be cutting 24 feet of 3/16 steel???? you might try a 12 ' piece of scrap to see how it goes first

Menard's

Yeah Jerry, 8 total cuts about 3 feet each. I called a local steel fabricating shop who has cut stuff for us before and he said he would have to charge me $ 300 to do it, so that made up my mind to do it myself. He has a waterjet but says the stream of water cuts through the one side and messes up the second side. He was going to just plasma cut it, which I could do, but I want to try this saw to see if it makes a nicer cut. Yep, I intend on practicing on some smaller pieces first, as you suggest.

Well, I just called and cancelled the order I placed today. Dan came home from work and we talked about it, and the one he had and took back was essentially the same thing, but from Sears. He said he tried cutting boxing plates for his frame with it and felt like it was going to kick back into his face any second..........his words," it was an accident looking for a place to happen. " It may be fine for wood and thin metal, but not 3/16, he feels. He said it also threw pieces of cut off steel like no tomorrow.

Since I am pretty Klutsy anyway and need all my fingers, I decided to not take the chance. Luckily, they were able to cancel the order. I guess we will be using a cut off wheel on a disc grinder to do it, with a guide to keep the cut straight.

On to plan B.

Don

that will work-- or even a skill saw with the cut off abrasive wheel

the saw worked great for cutting thru the nails in the flooring/subfloor we cut out and nice and close to the wall---but it had no depth control(base)
