Steve, is it the dovetails you are having trouble measuring on the existing toolpost? If so have a look for an article in MEW recently by Jaques Maurel about measuring angles. He has shown a neat pin and plate jig to help measure angles accurately, and it is really simple to make. It will allow high accuracy measurement of the dovetails.

Hi Steve, Thanks for the sketch, it clears things up a bit.

Attached sketch below shows how the angle positions could be measured using Mr Maurel's jig and a modified version of it to establish the angled face locations. Hope it helps.

Note that in each case the pins are screwed to the plates to make the jigs easier to hold in use, and the plate edge is back from the pin dias to ensure you are measuring from pin face as intended, not plate face or edge.

Hi Steve, just fyi if you wanted to read Mr Jaques Maurel's full article on measuring dovetails it is in ME 4588 june 2018, starts pg 842. Couldn't find it earlier this week in my mag stash, but did today.
