2nd attempt to explain chain-loop wedges

Experimental idea to vary toolrest height
Powered turners constantly vary the height of toolrest, because they seek to get the most effective cut. The scheme I outline below really helps me. IÂ’ll be interested to hear your feedback.

1. Take a loop of chain and fit an ‘S’ hook to one end: Image
2. Pass the chain round the lathe bed:

3. Connect the ‘S’ hook to make the loop the length you will need:

4. Offer the toolrest to the chain-loop:

5. Pass the toolrest inside the chain-loop:

6. Drive a wedge under the toorest to raise it and tighten the chain-loop:

7. To make different heights, use different wedges and loop length:

I can understand what's going on now Gavin and I'll look forward to seeing it all in action in Oxfordshire in May.
