Very nice, thank you for pointing out tung oil. If I have some, I'll try sanding a little again, then apply that, I prefer your results. If not, it's going to stay dark like this, it'll be more "distressed like" and fit in with modern hipster life.
Good news bad news. Good news: all three bottom vents now rotate freely. It'll be tricky to get them in shape. Bad news: the electrolysis is not as easy as I thought. The metal is covered in a black layer, which doesn't scrub off. It needs a wire wheel to remove (found a small one after digging through my drawers), leaving sort of a gold hue. This triangle is severely corroded. I am tempted to just use a chrome paint over it all and call it a day. My shirt is already full of little brass wires and I have a few stuck in my hair that will take days to remove.
Back to the vents - a minor OCD part of me wants to drill out the rivets, repaint the outside of the lid and base, then install shiny new lower vent covers and reuse the upper one. Probably not worth the effort or cost. Pricing this out, September 2019:
- grill grate $16
- charcoal grate $10
- ash pan: $17.50
That's already half the cost of a new one. Then possibilities:
- three vent replacement kit, $16
- triangle, $21
- high heat paint, $5
- misc stainless hardware, $2-8.
Aaaannnndddd.... that's a new 18"
This is all for the sentiment as a fun side project, and while cost isn't an issue, it's clear I won't really be able to get this thing like new. Might as well just start using it soon as the grates and pan arrive, and we'll consider the dents and any remaining rust as patina.
