Yesterday, I cleaned up some yard sale goodies.
The tiny door knob on the pub front door is pretty well shot. It's brass-plated with the plating worn through, so I thought I could clean that ornate knob up, paint it, and replace the old one. These are for a 1/4" square shaft of a mortise lockset.
I stripped the old paint with lye solution in the USC, then zapped on three layers of Rusto Gloss Black primer+paint, then baked at 225 for an hour. Came out alright.
Of course, it no longer matches the latch. I could strip the knob and attempt plating it with brass--but I've never attempted plating with an alloy--or just paint the latch key black to match. Yeah, that seems much easier.
