Upright machining?

[RAYLEE29]

I used the 19mm Axminster one set up in the pillar drill and kept cutting and checking till i was happy with the fit basiclly full nut and washer of thread sticking out the top and the largest bit of the taper just visible below the upright.
The taper is a good enough fit that after only tightening a little the need to be tapped to get back off.
