Gotta ask if an edge bander is even worth the headache for a home shop. Most guys I know just use iron on tape and a trimmer for the odd project. That pro label is just spray paint on the same cheap parts. Seen it a hundred times. Spending real money on a tool like that only makes sense if you're running a business and using it every single day. For the rest of us, it's a solution looking for a problem.

Man, I read that old grease can basically turn into glue over time.

Ever have a boss tell you something so simple it sounds dumb until it saves you? Mine made me check every single bolt on a scaffold setup twice. Found three finger-loose ones that would've been real bad.

Classic @mitchell.jessica, building a list that never quits.

Honestly sounds like a waste of time. My grinder works fine at room temp. You're just adding another step for a tiny change you might be imagining. Coffee is already complicated enough without turning your kitchen into a lab.
