thank you kindly for your comments.
I am in the Seattle area (read 'stretches of wet damp weather') so I was surprised at how well the remaining tiles are adhered. No loose ones.
Structurally it is remarkably sound.
My plans are to bolt on a daisy wheel top, should be easy to do because of the flip lever.
sand and repaint the hinge.
replace a few of the castor wheels on base.
drill a hole for a thermometer
repair fire box.
I am not sure how to drill the bbq port you wrote of. I was contemplating sawing out the front base daisy wheel and bolt and seal a slide door over the (large hole)...do you have more detailed instructions for tools and procedure for drilling bbq port? Your way sounds more efficient than mine.
I have to say your art approach to the tile intrigued me lol. I have not replaced tile on a bbq before so am not sure of the materials to use. I still need to research that. The seller gave me a coffee can full of the tile that came off.
sooooo a project.... : )
