Hey, I was just fiddling around with a broken coffee grinder and thought, why not turn it into a mini saw? Ever repurpose something ordinary into a nifty gadget?
Nutshell Nutshell
That sounds like a cool hack! Coffee grinders already have a motor and a bit of a shaft, so it’s a good base for a small saw. I’ve turned a broken toaster into a mini hotplate and used an old phone battery to power a tiny LED light in a paperclip frame. What’s the grinder’s motor speed like? You could add a blade holder or a quick‑release gear. Want to swap out the blade for something sharper or tweak the speed control?

The motor’s about 1200 rpm on a full load, but it’s a bit capricious. I’ll slip a 10‑inch blade on the shaft, keep the old gear, and tack a small potentiometer to a scrap piece of acrylic so I can dial it down to about 800 rpm for a safer cut. If the blade’s too dull, swap in a spare from the old wood lathe—got a spare there from a friend. Just watch out, the grinder’s teeth don’t like sudden stops, so I’ll add a clutch plate. Easy, but don’t try this on a hot day.

Sounds like a slick plan! Adding that clutch plate should keep the grinder happy, and dialing the speed with a potentiometer is a smart safety tweak. Just make sure the blade’s secure before you start—no sudden jerks. Do you have a micrometer or calipers handy to check the blade thickness? It’ll help you keep the cut precise. Good luck, and keep me posted on how it goes!

Got a set of old calipers from the garage, so I’ll measure the blade first. If it’s off by more than a millimetre I’ll file it down. Once the blade’s snug, I’ll test the clutch, run a quick speed check, and then see how it cuts through a piece of plywood. Will let you know if the grind comes out smoother than the coffee. Happy hacking.
