-Worked on the oil cooler install. Lots of head scratching to make sure I didn't mis-step. I settled on a location and started cutting out the hole in the back of the #5 baffle. I then match drilled the doubler for the oil cooler. I wanted to tie the bolt that holds the baffle to the cylinder with the oil cooler doubler so I made another larger doubler out of .035 and added it under the stock doubler. I then made two .063 doubler to space the baffle away from the cylinder. I layed out rivets for all this stuff and also the seal at the top. Disassembled deburred and prepped for riveting. I riveted the nutplates for the oil cooler bolts (3) for now.
Oil cooler as high an outboard as possible
Parts on the left-stock. Parts on right extra to avoid stress cracks - hope it works
