Making a 'Poor Man's Vibratory Tumbler'

This is a simple tutorial for making a cheap vibratory tumbler.

Once you've made the tumbler you'll need some tumbling media,
some cheap forms are:

Rice, sand (may be abrasive), flour (said to give a high polish)
and Poor Man's Shot (cut up your left over bits of wire so they are
about 5-10mm long, run them in the tumbler for a few hours at least
before adding anything to be polished).

To make a Poor Man's Vibratory Tumbler you will need the following:

Vibratory Sander
2L Paint tin (Clean)
4 short screws with large heads
Screwdriver
Tumbling media

Before you start make sure the sander is unplugged, and please be
careful!

These instructions show how I modified my own sander, if your sander
is a different design you may need to adapt the design.

Turn the sander upside-down.

Remove the sand-paper.

Remove screws holding base plate in place.

Remove the base plate.

Remove claps for holding the sandpaper in place.

Put the base plate back in place.

Screw the base plate back in place and place the paint tin in the
center of the sander and mark its outer edge.

Remove the paint tin.

Screw in one of the large headed screws so its head will push down
on the lip on the bottom of the tin.

Repeat for the second screw.

And the third.

Slide the tin under the first three screws.

Screw the fourth screw into place and gently tighten the other screws
to push the tin into the padding on the bottom of the sander (to help
prevent it from moving).

Load your media into the tumbler and let it run for a few hours. You should do this in short spurts
as the sanders are probably not designed to be run constantly.

If you are planning to use this as a wet tumbler put a lid on the tin and turn the tumbler on and off at
the power point: water + metal + electricity = bad!

Improvements that could be made include placing the sander in a vise, and using a timer switch to
ensure that the tumbler isn't run too long.
