Began fabbing of forward center baffles using the templates from Bill Lane. I'm using the Sam James cowl with Bills plenum so I tried to modify the center left baffle from the Van's baffle kit. Had to bend the side of the baffle backward so I may have to make a new one out of 0.032 sheet, but this was good practice. Traced the template for the center left side too. Began the iterative process of trimming the rear and side baffles for the 1/2” spacing to the top cowl. Must've had the top cowl off and on 50 times trying to work my way down to the 1/2” spacing. Finished the day with the cowling on and no interference, so now it just needs the 1/2” spacing. Photos are shots through the cooling inlets and rear shot of right baffle through the oil door.
