Are you tired of the same old video style from your favorite content creators? We can’t say that we were, exactly. But nevertheless, we appreciate this creative departure from [Eric Strebel]’s regular fare as he soups up his drill press with an old treadmill motor and a few extra features.
First off, that commentator in the video is right — 2.6 horsepower is a crazy amount for a drill press. Fortunately, [Eric] also added a variable speed controller and a digital tachometer to keep things in check. As an added bonus, he no longer has to get under the hood and mess with the belts.
We like what [Eric] brings to the drill press motor mod, which is already well-documented on YouTube. We love the re-use of an office chair bracket as a new motor mount. It’s probably our favorite bit aside from the 2-color forward/reverse switch plate idea: print it in whatever letter color you want with proud lettering, paint the whole thing black, and sand off the letters so the color shows. Check it out after the break.
There are many ways to make your own drill press, and one of the easiest is to mount a hand drill.
Did you miss the Industrial Design Hack Chat with [Eric]? It’s okay, you can read the transcript over on IO.

Sometimes there’s a satisfaction to be found not in the more complex projects but the simplest ones. We’ve featured wind turbines of all types here at Hackaday over the years, but HowToLou’s one is probably one of the least sophisticated. That notwithstanding, it does its job admirably, and provides a handy reminder of a parts source many of us might have overlooked.
At its heart is a motor from an exercise treadmill, which appears to be quite a powerful DC motor so that’s a source worth noting away for any future projects. To that he attaches the blades from a desk fan, and when placed outdoors on a windy day it generates enough power to run an LED head torch and charge his phone.
Of course, this most basic of wind turbines is not displaying its true potential in the video below the break. Were it mounted in a high position free from ground based wind obstacles it would no doubt catch a lot more wind, and in particular were it hooked up to a charge controller and a battery it could provide a much more useful power source. Then you could start optimizing fan blade designs… But this is a fun project that isn’t trying to masquerade as anything sophisticated, and it still has that potential.
This isn’t the first such simple turbine we’ve brought you.
