> Epoxy is looking so tempting right now

Don't know if I'd trust epoxy on its own with a moving part, ie
there will be some stress when the pot is turned and stops at the
extremes. MDF isn't very strong mechanically, it would be the
weakest link in this mounting, and it's easy to pull off the top layer.
Using the pot case tab will help

I might try a slightly under-size hole and either tap it or thread it
with the pot
