Drum Sander Made from a Treadmill | I built a DIY thickness sander from treadmill parts
I built a drum sander to handle the work that my thickness planer can’t. Basically, one treadmill, a roll of adhesive backed sandpaper and a few electronic components are all you need. With a 3hp motor and steel roller, this thing is unstoppable! …which isn’t the most safety-minded concept. If you build one, PLEASE make it more safe than mine!
If you make your own woodworking equipment please leave me a comment.
As for the DC Motor control circuit, I’m using an SCR (silicon-controlled rectifier) which clips off part of the AC waveform, reducing the amount of power to the output depending on the position of the potentiometer. The bridge rectifier switches the waveform to DC that’s needed by your motor.
Other components are –
The direction switch which reverses the polarity to the DC motor causing it to run in the other direction
Fuse to make it not burn (my projects often burn)
Two contact momentary switch for Lift motor control
Kill switch (fairly useless with so much inertia)
Power switch (or possibly the maime switch, if we’re being honest)
