Thanks for staying with me Per

Were they written in Chinglish

Just that first couple of sweeps with the Levers has taught me so much:
1, you must set the stops (they are still very stiff to move hence the graunched knurls on them so I didn't use them

)
2, You must use the stops - otherwise the tool moves away from the work as you sweep down the piece and you end up with a taper

2a, You might be in a rush but don't forget to set the height of the tool

3, This will be really good for free hand sculpture

More work to do... I need to replace both of the threaded knurled stops and add some of the intermediate nuts and think about putting increments on them.
