We love to see projects revisited, especially when new materials or methods make it worth giving the first design another go around. This twin-turbine vacuum-powered Dremel tool is a perfect example of what better tools can do for a build.
You may recall [JohnnyQ90]’s first attempt at a vacuum powered …read more

What is better than a tool? Two. What is better than two? Two tools tooling together. [tintek33] wanted a rotary tool to become an attachment on his mini lathe, the video is also below the break. Fortunately, Dremels and Proxxons are built to receive accessories, or in this case, become one. Even if the exact measurements do not apply to your specific hardware, we get to see the meat of the procedure from concept to use.
We start with where the rotary tool should be and get an idea of what type of bracket will be necessary. The design phase …read more
Rotary tools are great little handheld powerhouses that fill the void between manual tools and larger shop machines. They’re also kind of expensive for what they are, which is essentially a power circuit, a switch, and a high-RPM motor with a tool coupling on the shaft. If your tooling needs are few and you have the resources, why not make your own?
[DIY King 00] built himself a cordless rotary tool for less than $10 out of commonly-available parts. It doesn’t run nearly as fast as commercial rotary tools, but that’s not necessarily a bad thing. He made the body …read more
We’ve all seen Dremel drill presses, but [Tuomas Soikkeli] has created a full-fledged (albeit miniature) workstation using his Dremel as the motor. He has a gnome-sized belt sander with what appear to be skateboard wheels turning the belt, with the Dremel’s toolhead tensioning the belt and turning it as well. There’s a wee table saw, petite lathe, cute router, etc.
The Dremel attaches to the base via the 3/4-to-1/2 threaded end upon which specialized tool ends may be connected, and which DIY add-ons (like this light ring that we published previously) typical connect. Though in truth the threaded end varies …read more
For your high speed, low torque needs, few things beat a rotary tool like a Dremel. The electric motor has its limits, though, they generally peak out at 35,000 rpm or so. Plus there’s the dust and the chips to deal with from whatever you’re Dremeling, so why not kill two birds with one stone and build a turbine-driven rotary tool attachment for your shop vac?
Another serious shortcoming of the electric Dremels that is addressed by [johnnyq90]’s 3D-printed turbine is the lack of that dentist’s office whine. His tool provides enough of that sound to trigger an attack of …read more

We really don’t know if the world needs it but we’re sure glad [johnnyq90] took the time to build one. We’re talking about a nitro powered rotary tool. Based on a Kyosho GX-12 nitro engine, commonly used in R/C cars, [johnnyq90] machines almost all other parts in his shop to make a really cool ‘Nitro-Dremel’. But success didn’t come at the first try.
The first prototype was made using a COX 049 engine but the lack of proper lubrication cause damage to the crankshaft. Because of this setback, [johnnyq90] swaps it out with a O.S Max 10 Aero engine he …read more
There are two types of people in this world: people who think that PVC is only suitable for plumbing, and people who don’t even know that you can use PVC to carry water. Instructables user [amjohnny] is clearly of the latter school. His PVC Dremel drill press is a bit of an oldie, but it’s still a testament to the pipefitter’s art. And you can watch it in action in the video embedded below.
Things we particularly like about this build include the PVC parallelogram movement, springs around tubes to push the Dremel head back up, and the clever use …read more
A Dremel is a fantastically handy tool to have around the workbench, but there is one glaring and obvious downside: you will always run out of cut-off discs. if you’re trying to break into a fancy snap-fit enclosure that has been inexplicably glued together, you’ll invariably need to run down to the hardware store to shell out some cash for a tiny tube of cut-off disks.
[KB9RLW] has the answer to this problem. He’s cutting wood and plastic with paper discs spinning at 35,000 RPM.
The paper used for this application is just a piece of junk mail or heavy, …read more
