I have access to a regular sized McNaughton coring system at our senior's workshop but no-one knows how to work it. After reading the short instructions and watching some of the videos available, I have some questions I was hoping someone might answer.
A) is the gate ( the round thing with 4 fingers the tool slides through) grub screw tightened to allow the gate structure to swivel, or to be fixed/ unmovable?
B) The instructions suggest a safe rpm speed but dose not say what a "safe speed" would be. What would a good rpm speed for a 12 in dia oak blank might be?
Would it be better to use another type of wood to start?
thanks
