up-right bushes

[Trif]

I've just turned the up-right bushes using the plans published on the forum.

So a big thanks to the member that made the plans available.
I've just got to machine the tapers, I've calculated the taper angle at 2.9 degrees, my intent is to test this on an offcut using the ball joint taper as a plug gauge.(that is when it arrives) That is unless someone knows a better way of getting the right taper?
cheers Trif
