Thought I would post this about a small adjustable table for making small parts on, to make the table you need five items,




1 (Copy).jpg
A bowling ball, here in Australia these can be bought cheaply in some Charity shops




2 (Copy).jpg
Cake baking tin or an old cooking pot






3 (Copy).jpg
6 inch length dowell for handle





4 (Copy).jpg
A piece of thick felt to go round the top of the baking tin, you may have to wet the felt to get it to conform to the lip of the baking tin, but once you have it in place put the bowling ball on and when it is dry it wont move out of place and the weight of the ball and the grip of the felt will hold it whatever position you want, see next pic

And a piece of wood for the table, you can make this whatever size you like, you drill through the wood into the ball, then enlarge the holes in the ball to accept wall plugs for the screws to go into, when you have screwed the table part to the ball you might want to reinforce the under side of the table with some car bog filler, as in photo.

Make sure when you fix the table it is just above where the Dowell handle will go so you will have lots of positions
to turn it to, see photo. Use a dowell that is a tight fit, you can glue it in if you want.

These next four photos show the versatility of the table, you can fix a vice on it if you want, or just clamp the items you want to work with, its really adaptable. I have .
