Brief Description: Sec FF2-plenum step 1

|
I started off on the fiberglass modifications to the plenum today, I noticed right awat that the prop control rod ran through the intake plenum. I cut out the interferring part and will glass a patch that fits around it. There was also some interferrence between the plenum and the crossmember and the lower portion of the #2 baffle, so I cut that out as well and will reglass. I'm going to have to make some major modifications to the right intake area anyway. The right rear portion of the plenum needs to be extended aft about 3/4" in order to utilize Van's baffling, so taking a tip from Ed Hayden, I cut the portion off with a dremel tool, clecoed some plastic covered .032 to it and then expanded it aft, and reclecoed the .032 to the plenum. this will allow for the exact distance when this piece is reglassed. But before attempting those I needed to have the plenum 'hard mounted' to the baffels. So trimmed any remaining posts on the plenum that were interferring with it's positioning, and then trimmed each cyl side baffle to be flush with the top of the plenum, did this on both sides. Fabbed some .032 reinforcement tabs, match drilled, countersunk and riveted these (6) to the top of each cyl baffle. I went back and drilled #19 hole in the center of each for a #8 screw, and then matchdrilled the plenum. Took everything off, and then drilled and riveted #8 nutplates to the sides of the plenum. Reattached the plenum after hard mounting the baffles w/ screws, and traced the trim line for the rear of the plenum with a fine line Sharpie. Removed the #6 and #5 baffles, and trimed them and remounted everything.
