Its fairly simple to calculate the projection of a tool to be honed from the front edge of a honing guide in order to achieve a specific angle. The table below is only appropriate for the Axminster de luxe honing guide (to nearest millimeter).

The formlula is easy to use in a spreadsheet for any guide.
Height, from bottom of roller to top of support plate/SIN(Required angle*PI()/180) then deduct the distance from the centre of the roller to the front of the support plate.
It is easy to make a jig to measure the tool projection and set the tool square.
