I want to install a butterfly valve to control airflow to the oil cooler, but the one that I bought way back when from airflow systems has the mounting ears in a really goofy location for what I want to do. Specifically, one of the ears was going to be hanging out into empty space, or I was going to have to move the whole thing in and down about an inch. In an effort to take advantage of every molecule of cooling air, I wanted to optimize the location, so I cut the flange off, fabricated another so that I could orient the mounting hardware better, and took it over to a friends house for him to tig weld it together. It came out really nice. I also discovered that a couple of the worm clamps on the oil return lines were clocked so that they were in the way of teh baffles and/or eventually the baffle tie wires so I spent some time adjusting those. Wish I had known about this before I had all the systems on the engine as it's pretty cramped to get in there with everything installed. Attis point, the baffles are coming together nicely.
