Talking about marking gauges, I have one similar to the one made by Garage Workshop, but there are situations where it is not usable.
- need for marking a really tiny distance
- need to follow tight curves
Here is the one I made this week end :
The main rod has an 10 mm diameter and the transversal one, only 5.
The marking pencil is reduced to a 2mm diameter lead.
Obviously, the screw above is not necessary, the fit is just tight enough.
This is made out of beech, waxed with carnauba.
The setup here is just 1 mm.
