I'm in the middle of restoring an ER 100. This my first brush restore. I'm tempted to simply epoxy in the knot without filling the handle (w/ epoxy, coins, etc.) or build a shelf. I'm uncertain if making the handle slightly heavier is worth the trouble. I also am not sure if there's any technical reason to build a shelf by either inserting a cork or glue in a disk.
Comments and opinions from experience brush restorers please.
