Having recently bought a new mill with an R8 spindle, I have made up some new R8 arbours for my boring head, the gear cutter arbour and a spare arbour for a future project so they could be used on the new mill.
The old mill had an MT3 spindle and it was a big job to make MT3 tapers to a reasonable accuracy. The R8 arbours turned out to be somewhat easier, with the aid of a taper template that was made to match a couple of R8 tapers that I bought with the mill.
Pictures below of the R8 arbours, the old MT3 arbours, and the template.
