We had the pleasure of a visit from Dave Stovell of https://www.stovelldesign.co.uk/ demonstrating some green woodturning, specifically how to create shrink pots.
Shrink pots are created by turning a small green log (section of branch) to remove some or all of the bark and then hollowing it out using incannel chisels and then using a small scorp cutting a groove at the base into which a seasoned disk of timber is inserted.
The reason for using green timber is that as the timber dries it then shrinks around the disc forming a tight seal. A lot of skill is needed to ensure both parts are just the right size to ensure a tight fit without splitting the wood.
The evening was enjoyed by all present and there were a lot of comments from people who were going to try it although they drew the line at painting their lathes pink (Dave did say that wasn’t essential)
I would recommend having a look at Dave’s website (click on any image)
