New shell diameter/bearing edge Method?????
This pot is 11 and 3/8ths in OD-diameter. I thought it was close enough to 12.
NOPE.
When the head went on, I could see there was too much space between shell and head rim.
So...I looked for a metal that I could bend around the shell to make the diameter larger at the edge. Again......why do I do this????.....Because I learn something each time.
Soooo No on finding the metal.
Then I went to GC to get a EC2 12" head for deep tone. maybe.
and looked at the drum head.
And there it was.......Use an old head rim and cut it down and attach it to the shell.
But how to attach?
First set it up higher than the existing shell. (New bearing Edge is the Head Rim)
Clamp it, measure it up from flat table and drill a hole from the outside through the head rim and the shell. Tap it with 6/32 tap and put a screw in from the inside.
YES threads will go both ways.
So I now have new/old fashioned round over edges. The round over used on Remo Head Aluminum rims. It tunes much better. for a pot........
