Very simple acessory mount using the screw holes on the side of the spindle mount carriage.
So far ive attached a 360 degree swivel knife from the inventables website to use as a drag knife and a pen. Ive added a couple of skate bearings just to make the swiveling better
Still in prototype stage but works well. So far been cutting cardstock (400 grams per square meter) for making boxes.
It’s a bit hard to see in your pictures (and on my iPad), how did you mount the knife in the bearings? Mounting the bearings looks simple enough to, but I’m intrigued how you locked the knife into the bearings themselves.
CALL IT COINCIDENCE the bearing just sits there . slides freely on the smooth portion dosent slide on the roughened grip portion. i think most x-acto knife handles are similar
