Here is a picture of a good tool to tension the locknut when you are doing the valve adjustment on the Templar. It is a 12 point, so you can place it in twice as many places as a combination or open wrench (spanner), and it seats completely around the nut (not angled). The pic in post 46 above shows the access. Offset 12 point boxend wrench is just awesome for this.
I use this because the tappet has a flathead slot. It gives you real nice control over how much tension you place on the nut.
My CG clone in the Storm has a squarehead tappet, so I use this tool. You can see the square socket on the long end of the tappet tool. The same square socket is on the other end of the Tee (two sizes, one each end of the Tee).
