Introduction: Hack a Drill - Powerful Gearmotor!
In this Instructable I will show you how to get a powerful gearmotor from a cordless drill!
I found this cordless drill in the scrap bin at a second hand store. When I got home I discovered something odd (video...)
Step 1: Materials
- Cordless drill for hacking!
Step 2: Tools
- Philips head screwdriver
Step 3: Disassemble
Unscrew all the screws holding the two halves together. If it doesn't come apart, there might be some screws under the stickers or the grip pad.
Step 4: The Guts
Step 5: Removing the Chuck
Inside the chuck is a screw. This screw is threaded in reverse so that when you turn it to the right, it comes loose. This part might require some gentle persuasion. Don't throw away the screw, you'll need it when attaching stuff to the motor later.
Step 6: Removing the Clutch
The clutch is attached with two screws. It's spring loaded so be careful removing it. Also, removing the clutch will expose the ballbearings inside, hold the motor upright so they don't fall out.
Step 7: Fixing the Gear
Remove the ball bearings inside the clutch by turning it upside down. To fix the gears in the 'drill' setting we need to insert two set screws in the holes where the ball bearings where. Screw them in until you can turn the motor shaft without it slipping.
Step 8: That's It! We're Done!
Enjoy your gearmotor!
Step 9: Extra
We got a lot of parts for other projects!
