Isolation Gaskets, as the word implies, help isolate the metal parts from the drum shell. The advantage being that anything securely attached to the shell will in some way interfere with the resonance. Our DIY Isolation Gaskets simply add a buffer between the shell and metal part, reducing the amount of interference. In addition, ISO gaskets look cool. Especially with lighter colours, silver, chrome, or sparkle finishes on the shell.
These DIY Isolation Gaskets can be made of craft foam, inner tube, or as in this example, drawer liner. The drawer liner we’re using here is intended for tool chests and is quite heavy duty, with a reinforcing weave in the middle.
The only tools required are regular scissors, a hole punch and a marker.
DIY Isolation Gaskets
Making the DIY Isolation Gaskets is about as simple as it gets, but can require a bit of patience. Some tunes and a beverage of some kind may be conducive to good results.
Step 1, Press the lug or bracket down on the material so the screw posts make a temporary indentation in the material. Use the indentations as guides to punch the holes.
Step 2, Insert the lug or bracket posts into the holes and cut with scissors 1-2 mm outside the perimeter of the lug/bracket.
Sometimes it’s necessary to mark the cut line with a marker, rather than using the bracket as a template. Just face the side with the marks toward the shell when finished.
That’s all there is to it. Take your time following the lines with the scissors for best results.
