idosubaru Posted September 21, 2009 Share Posted September 21, 2009 can you stop in a store and measure them? used ones might be a slightly different measurement, have been turned before? i think i have some EJ drums lying in my garage somewhere, but i don't have anything accurate to measure them with.

zukiru Posted September 21, 2009 Author Share Posted September 21, 2009 I guess what I want to know can be determined with measuring shoes. drums are special order. the ea ones at least... I really don't want to pull mine yet, either. if any one just knows what size they are "called" like are they "10 inch disks" found something EA drums are 7 and 3/32 inch... I assume this is overall diameter Gary, a "close" measurement is fine... Link to comment Share on other sites More sharing options...
