Home-made mini-sander

I wanted be able to put a mitre on small pieces of MDF which are used to make walls. I've decided that mitred corners look nicer than trying to interlace or butt joint but sanding the mitre is a pain. I looked at bench sanders as a way to do this but the commercially available tools are quite expensive (around the £80 mark) and mostly very large (sanding disks around 8 inches).  So I thought I'd have a go at making one myself.

 

I laser cut the bulk of the components in 6mm ply and 3D printed the 'cone' that holds the grit paper.

The motor was purchased on Amazon for £12. It claims to be 'high-torque' and operates on 6 to 12v. Seems quite happy powered from an old Maplin power brick.

I've made the front so it can be hinged to 45 degrees, I might try and make a sliding gate of some kind.

Initial tests show it seems to work ok. I think I might reprint the 'cone' with a slightly larger hole. I had to drill it out to 5mm because the hole came out a bit small on the printer and really needed a drill press to make the hole perfectly vertical, it is close but there is more wobble than I 'd like.

 

However the results look ok, this is a bit of 1mm ply which I'd laser cut some bricks on the other side of.

I am going to need to sort out either some dust collection or a mask. I don't want to breath is stuff in as it might be carcinogenic (bit late to worry about that!)

 

Now to get on with building more fiddle-yard cassettes.

Hi.

 

Lidl have had something along these lines very recently - the front hinged plate is very much like what you have made.  £29.99, I think.  We’re still some in my branch at the end of last week - I think it was maybe an offer from about 10 or 14 days ago?

This is maybe the third time they have had them?  Coincidentally Monday was the first time I’ve used mine in anger.  If you get one then try removing the adjustable table (you need to do this to stick the sanding disc on) as on the first one I had the captive nut to take the bolt that holds this on immediately came adrift somewhere inside!  So that had to go back.
