Redneck, Fast, Dirt Cheap, Oscillating Multi-tool





Introduction: Redneck, Fast, Dirt Cheap, Oscillating Multi-tool

About: As being a long term unemployed, because nobody wants to hire anybody with no professional experience here in Spain, I have to tinker how to make stuff without getting broke, for the things that break down, ...

I always wanted one of those tools, but are pretty damn expensive, and i just needed to cut some insulating foam, so i made this dirt cheap mod on my sander, and the results are way better than i expected!

Step 1: What'cha Need...

Well, this is a very straight forward 'ible, so let's make things easy.

- Delta sander

- screwdriver

- metal blade

- scissors for sheet metal

Step 2: Unscrew the Sanding Base

You need to remove that velcro stuff

Step 3: Cut and Screw

grab the snips and cut the blade, the longer you cut, the more will vibrate, but don't cut too short or you won't cut anything!

Step 4: Done!

tighten that damn screw!!!

Step 5: What's Next?

test with some blades and see what happens!

    I have one of the oscillating tools, but there is a whole lot of potential for adapting regular blades to fit on them for a much better price. You can get the tool really cheap but the blades will cost you!

    I'm afraid of buying one of these because i don't know the result of one of those machines. I got a dremel, this sander, and a jigsaw, and, with this tools I can make pretty much everything i want. What are the pros of this tool? One, is the advantage of having one machine instead 3, but I mean in terms of cutting, is it worth the try?

    For the jobs that it does best it is invaluable. There are some jobs that it seems there is no other (power) tool that can do the same job. The plunge and flush cuts that you can do you could arguably try and use a sawzall but not with anywhere near the precision- you don't have to bend the blade to cut flush with an oscillating tool.

    It is also a very safe tool- you would have to work really hard to cut yourself with it because your skin moves enough to move with the oscillation of the blade rather than be cut by it, so you can literally put the blade on your skin with the tool on and come away completely unharmed (yes, I tested this claim personally : ).

    With the variety of blades available it can do all manner of jobs, including those of a spiral saw and other more specialized tools. I don't use mine all the time, but have managed to acquire (at very good sale prices) a cordless and air powered version as well. I originally bought a Dremel brand tool and it quickly died so I bought a Ridgid which has interchangeable heads, but that's another story.

    It is also a power scraper, which is how a buddy made his wife feel better about his recent purchase of a cordless one. It isn't a necessary tool until the 5 or 6 times a year when it is the only tool that will do the job, and then it is worth every penny. The cheapest way I have found to get into one is to get the single speed tool on sale from Harbor Freight if you like shopping there.

    Hope that helps.

    Thanks for the explanation! It's a shame here in Europe we don't have Harbor Freight, they have very good prices as far as i could read in some magazines some friends take me when they travel to the US. My Dremel has got 3 years now and it runs like the first day I bought it, it has a good price for the value, is a very versatile tool. So i'm thinking about improving my sander and see what happens, and if doesn't work, maybe i buy one of these!

    It certainly seems like another Instructable should be in the works: modifying your sander to accept the multi-tool blades! :)

    Of course, you could always rig up a way to mount the oscillating tool blades to the sander and maybe skip buying it altogether.

    As i could read here, , the principles of the mechanism are pretty much the same, so my next step is to make some kind of a blade holder or something, using as a blade, let's say grinder blades (for tiles), an old wood handsaw which i can cut a piece and hold it in place, sander (duh), re-fit the metal saw to cut metal, because the end wiggles the way i screwed it, and it needs to be a rigid part... And of course you can go ahead and mod it the way you want!

    Thanks everybody for yourt positive feedback! i never expected to get so far with this ible hehe!


    My dad has an oscillating sander (I believe that's the name), And I'll have to keep this in mind if I need one, Thanks for sharing!

    Orbital, I meant...

    Brilliant hack! Now i need to make one for myself. I cut a lot of foam and this tool is a great idea to get into the tiny corners for finer shaping.
