I had thought of using my lathe to turn some foam heads, but as I was banned from the kitchen after turning cork handles in there, I though it best not to upset the other half.
Good video though, I think I have a dremmel in the shed.
Note: Do not have a lathe in your kitchen...it upsets the cook in the family, especially if you wait until she is in the USA and she then wonders why there is cork dust all over her pots and pans
