Fabrication Thread: What have you made?

" Surge tank " with thermostat housing for my W-9's.
Coolant is fed into the block through the center core plugs and exits out three ports in the valley side of the head.
I had help with the welds and as primitive as they look , there are no leaks.
That only took three tries with the pressure tester.:D
Milled a chunk of 3/8" for the top and plunged a 1 1/2" end mill for the stat.
Bent the sides up to eliminate two seams. ( .125 " ) whipped up a bottom , drilled holes and welded in the bungs for an fittings.
I wish there was something commercially available for this......I couldn't find it.
