Pumping CAPA 6800 meal...
I ran the CAPA 6800 meal through the 6.35 mm polymer screw pump. Both the wood and the metal drill bits pumped the meal successfully. Interestingly, the metal bit had a smoother pumping action than the wood. That was probably because it has a closer fit with the pump barrel than the wood auger bit does.
I was able to rotate both wood and metal auger bits with my fingers, which means that the 200:1 gear motor that runs Mk II will run the pump. Whether it will develop the 40 atm head pressure required is another matter. Still, it's a positive sign. :-D
I suspect that buying powder or flake CAPA resin would be a better idea but we're not sure of that yet. You'd probably be well-advised to put off buying for a few days till we have a better idea here. :-)
