Core plugs.
More rust-treatment. (45% phosphoric acid, no special brand.) Thermostat is an 82°C, 54mm jobbie. Seems pretty common.
Spotted a bit I missed while painting the block. Touch that up while I have the paint out for the water pump & thermostat housing.
Hang the pulley & fan on the front, just so it looks like I've made more progress than I have. Still need to fit all the gaskets, little stub of rubber hose between water pump & thermostat housing, and get all the bits fitted up.
S'pose I'd best tackle this, then...
Choppy choppy!
Peeling the onion: Layer after layer, and lots of tears.
Skipped a bit. There's video, anyway. It'll only take me ... checks notes A year and a half to get around to editing it.
Blurry, and doesn't show what I wanted to show, which was that the upright there now has some box section joining it to the crossmember, rather than air and wishful thinking.
Two-ish(?) days in a row I've been there 'til past 9pm, cutting, grinding, and welding. Starting to have something to show for it. Need to figure out what my next list item is for the engine; managed to miss out on going getting a bottle of argon for the tig welder, where for once I had a Saturday morning available where I could go down to the local hobbyweld stockist...
...and instead, I got mugged by bills & unit rent coming out; leaving me with £80 for the week. Ah well. Bank holiday weekend coming up, so hopefully I can at least get some more bodywork done. Might even push the boat out & get a holesaw of the correct size, so I can drive myself mad trying to cut out the exhaust flanges!
