My custom drums came with generic rims mounts which work quite nicely for protecting sustain and resonance. However, the wing nut of the gibraltar bracket for connecting to the L-arm stuck out too far too fit in my hard cases. Also, my preference for finger tightening tension rods from the side (between the lug and rim) was blocked on four lugs per drum. Additionally, the generic rims mounts are pliable and if they don't match the curvature of the drum shell so the holes line up perfectly, there is a small amount of side pressure at some of the tension rod sleeves (can't remember the part name). This can effect the feel when tuning. Anyone else experience similar problems? I decided to take matters into my own hands a few months back and imitated the DW/PDP style of engaging four lugs, but closer to the shell. I am quite pleased with the results and no longer suffer from any of the above. Anyone else do something similar? The metal is an aluminum bar from a home center that I rolled to carefully match the diameter of the drum. Then drill the aluminum with a hole saw big enough to accept the rubber grommets. Refine with a file. Rubber grommets from Amazon were thinned with a belt sander.
