Hi Aaron! I won't be home until late Saturday, but I have a drawing I did, showing this spacing from a Rogers 60's Headliner kit and also the spacing from a COB Dynasonic. What is interesting is that the distance from the top is different on each drum! Makes no sense, since the tone control mechanics are a constant! I have a picture showing how far above the top edge of the 8x12 tom the muffler sticks up!Anyone know the correct hole pattern (distance from top edge and then spacing) for a standard issue 60s/70s Rogers muffler off the top of their head?
Thanks to Dan's posting, it's obvious that Rogers didn't seem to have a template to place the muffler the same distance from the top edge for each drum! I'm posting the diagram I drew back in 2007 from a Headliner kit I was restoring. Also a picture of the 8x12 tom, showing how much the felt stood above the bearing edge when in the "horizontal" position. The floor tom was much better. However, the position for the COB Dynasonic was perfect! Even on many of my newer COB 5x14 shells, the measurement is still the same.I measured this morning. Looks like the top hole is 2" from the edge, to the center of the upper hole. I measured a ft shell, and a couple of snare shells. All within 1/16" , more or less.
