Bicycle Powered Sander


[Andy] does a lot of framing and needed a way to sand down pieces at proper angles. He goes by the moniker [Organikmechanic] on YouTube, and as such is trying to rely less and less on electricity — so he’s created this hand-powered sander using components from a bicycle.

His first iteration just used the spindle off of a bicycle wheel as the main axle, but he quickly found it wasn’t rigid enough for the sanding disk. Instead he decided to make use of the entire crankshaft assembly off of an old bicycle. He cut the frame down to size, removed one of the pedals, and shortened the other one to a more useful hand cranking length. The main gear of the bicycle provides a large and sturdy mounting surface for his home-made sanding disk which consists of a large piece of rounded chipboard.

It’s a pretty clever use of recycled parts — but what do you think? Are you environmentally inclined enough to give up your power tools? A full video explanation of the project is after the break.

HDD power tools: the sander

At first we thought this looked hastily thrown together and quite possible useless. Then we watched the video, embedded after the break, and realized it is quite a handy bench sander. [Mhkabir] opened up an older hard drive, removed the read head, and added a piece of carefully cut sand paper. When you hook it up to your bench supply you’ve got a small sander ready to use.  We can’t wait to try it on some small PCB edges. Now that we’ve seen a sander and a chop saw, we wonder what’s next?
