Hollow shaft extruder

[rqthree]

On the Veritas tool, neither the cutter nor the shaft rotates during use. The cutter scribes the wood, and the shaft is rotated to a new cutter edge position when and if the cutter becomes dull.

The screw just holds the cutter firmly on the end of the shaft. The cutter is not supposed to rotate at all.

@rqthree So it's probably not 100% round, because it's not relevant for the actual usecase?

I think, we have to look elsewhere then. The blade extruder only has a commercial future, when we find a way to build it economically.

For the rotor body to be adjustable to the blade diameter, I thought of an arrangement like this:
Three individual bodies which are held together with an O-ring to provide adequate pressure.
