So I知 in the planning stages of building myself a small display for my brushes and those to come. I知 a novice at brush making, but am looking to countersink magnets into the base of the brush handles for upside down hanging. Any advice would be great if there is anything someone has tried that would be good to know up front.

I知 planning on using either 12mm x 3mm or 15mm x 3mm disc magnets but am not sure if I should countersink them further than the 3mm and use epoxy or acrylic as a thin layer on top of that. The other option is to leave the magnet flush with the handle base.
I知 leaning towards not having the magnet flush because I don稚 want there to be a chance of it dropping and potentially breaking. It would be attaching to magnets that are a bit stronger; Neodymium bar strip magnets.

What are your thoughts regarding magnetically hanging brushes upside down?
Cheers!
