This is also new to the industry.  The joint is ground to make a perfect fit.   Because this industry is not pure science a joint with a slight leak is ok.  Many hand made joints will never be ground as many of the blowers lack the equipment to properly grind a joint.

We find a non-ground joint to almost be better for this industry as if it is too perfect of a grind, the joint and stick to the other joint if pushed together too hard.
