video Save cash - use trash. Home-made tools - Hand-powered sander. Ponceuse fabrication mason. Bricolaje una lijadora de disco
A hand-powered sander made from scrap. We're powering down on all household items, including tools. I use a mitre block but it's never accurate enough so I wanted a sander to obtain a better mitre joint. By altering the guides you can also use it to square up any sawn edges.  This little project ironically uses hand and power tools to create a hand-powered disc sander. I used the power tools to save time, as we have a lot of work at the moment but it can be made using hand tools alone. The disc, for example does not have to be round and if you use a thicker chipboard you will not need the router..

Une ponceuse fabrication maison des matières récupérées. J'ai utilisé les outils électriques pour la vitesse, mais tout le travail peut être fait avec des outils à main.

Una lijadora de disco de material recuperado. He utilizado las herramientas eléctricas para la velocidad pero todo el trabajo se puede hacer con herramientas de mano.
Very effective. You could get more of a flywheel effect if you used the rear wheel with the chain to the pedal. Maybe a kids bike, one with coaster brake. Just thinking out loud.

Yes, that was what I was going to do but I couldn't work out how to attach the sanding disc. Initially that was why I tried using the wheel spindle on the prototype but it was only when I did it, I realised I would not be able to mount the disc to the wheel. The other thing is I wanted the sanding wheel to turn slowly for the precision, a fast wheel means rapid mistakes! Thanks for the ideas, much appreciated. All the best Andy
I've seen a rather nice design for a treadle lathe using a bicycle freewheel mechanism and flywheel that might be adaptable to this (in a Fine Woodworking book on homemade tools). Though for small projects this is excellent as is.

Funnily enough I was thinking about having a go at making a lathe using a bicycle but it's still on the back-burner of my mind!!! At the moment I have more ideas for projects than bicycles but luckily we are coming up to the tourist season and that means more bikes at the Dump. Thanks for your comments much appreciated, Andy

There are circular sand paper discs in stores that uses a velcro sistem to attach to powered sanders.

What about make one wood disc (with oppposite velcro side) to attach them? you'll change sandpaper quickly everytime you need, with only one wood disc.

Good idea and helpful suggestion. I've never seen those sort of sandpaper discs. All the best, Andy

When it is time to replace the sandpaper on the chipboard disc, you could turn the crank while gently pushing a straight piece of wood with coarse sandpaper glued to it into the disc. This would be slow, but it would remove the wobble or mutation in the disc surface.

Good idea! It is running true now. Apropos of the discs I did think also to make several discs for different grades of paper, for all kinds of jobs. Thanks for your feedback, much appreciated. All the best from France, Andy
