Panhard Cylinder Liner Rebore Update 4

One of the areas I had to improve was the direct reading of the Whatton Boring Bar now that I have converted it to some readily available indexable tooltips.

The dedicated micrometer was not touching the tooltip, because the tooltip was lower than the anvil. A few moments on the lathe to test the idea, and bingo.


Here it is in situ, that’s attached to the anvil, with the micrometer fixed to the boring bar.



I just have to set the tip position and to do another test bore to establish the actual bore size measured by the three point bore micrometer versus the indicated reading of the Whatton micrometer.
