Thank you for your replies.
I think I may end up with the camera, it looks as if it should be more accurate than the laser and need little or no adjustment for depth.
You make an interesting point regarding the smaller cutter which as you say should give a lighter cut, something I had not previously considered. Have been using both the Munro and Hamlet Big Brother cutters on a rig made for me by a toolmaker friend, which has served me very well for a number of years, though it has to be said, I now find a tad aggressive for my ageing bones. So I’m rather looking forward to an easier/smoother ride!
