Thanks Graham, thats a beauty of a machine and the quality of the work produced is, I think, second to none.
I wonder how long it will be before we can all afford to buy one (without taking out a bank loan) ?
I made the other two arms for my Z2 lift mechanism. It really looks so wierd that I just had to post a picture. (If I didn't know what it was I don't think I would ever be able to guess it's purpose)
I still have to fit the tyres to the bearings but so far and perhaps suprisingly it works exactly as expected.
(it rests on three points and supports a plate which also rests on three points - as the centre part has an internal spring, acting in torsion, it will support the weight of the top plate and the working medium whilst allowing verticall movement with a parallel motion).
Tweakie.
