Fiver, I am certain that MP makes mold halves separately, with enough precision that
they just go together. How do I know that? Because I have a mold from him with one
cavity half misaligned by about .1" to the one across the way, and the other cavity aligns
perfectly. Clearly both sides of the cavity are not cut at the same time. The workpiece got
moved between first cavity cut (correct) and second (offset). He replaced it, of course.
I am pretty sure he has carbide profile cutters made and then can cut whatever diameter
he chooses, by running the cutter on a circular path, down to the point when the circle
turns into a point and the 'profile cutter' becomes a cherry. I saw some images on his
site that showed a beautiful cutter which was clearly for a Keith design, likely a 429421,
but was too small in diameter for the length......a profile cutter. This is why he can say,
"what diameter would you like for this design?" and make .429, .430, .431 .432, etc
without any extra charge. Just program a slightly different circle diameter for the cutter
path.
Spectacular mold quality, though.
Well done, Brad. I have considered trying this and can't quite work up the urge.
Clearly not easy, and very possible to total a good mold - and Eric has done
a few for me, and they are SO nice. Insufficient curiosity and bravery, together.
