I skipped the cabin heat knob assembly and moved to the oil cooler box assembly. I deburred everything and did a dry fit to final size the holes. Then I primed and painted with high temp paint. Next I riveted the top section on and fabricated the wood board to use later to protect the oil cooler fins when I pile on some weights. The next few steps need to happen within a short time frame, so I’ll put that off until next time.
