I've been tinkering about with it for long enough now so I decided to make a nice wooden base.
So I salvaged a chip off the old thrown

I don't know what sort of wood it is some sort of oak judging by the way the grain runs up and back, when we bought it, it had a label proudly saying "made in the USA" so perhaps some of you guys will know what it is.
I must say, with the greatest respect, you guys know how to make a darn fine comfortable thrown


It machined up very nice.

And here's the final video, it runs real well but for the video it was very temperamental, after the video I put it on the bench and it ran bountifully, I think we may have some sort of gravity effect on the linkage.
I'm revising the drawing at the moment so will post them for down loading in a few days
