I've had the better-half at me for some time to make a Lazy Susan and have put it off because I couldn't get an idea of the right size for us.

Problem has been solved by Aldis stocking slate ones at £5.99 - very basic but a good pro-tem solution at that price.

Can someone come up with a DIY material for sealing it? I've googled on the topic and only find commercial items that would cost more than the original purchase. I've got various waxes and oils associated with wood turning.
