Great idea. I do have the Kliebert viscosity data on hand. I'll see what Festool has to offer and compare.
I think a glue designed for a lower feed speed would also be better for the Conturo. I would imagine Kliebert lists recommended feed speed for their products.
Dorus recommends KS 224/2 Low viscosity, fast melting EVA hot melt specifically designed for manually operated edgebanders.
Holzher is the only edgebander I know of that uses cartridges. They made a hand held version at one time, I have always wondered if they make the Festool bander. They are both based in Germany so??
