Remember a few weeks ago when I said I picked up $4500 worth of baffles? There are 16 different baffles altogether. I had 10 pieces made of each one. When I picked them up, there were 13 sets of 10. I figured I'd miscounted and left it at that. I was excited just to get the baffles.
Turns out, the baffles for cylinders #2 and #4 and the baffle that holds the oil cooler were missing. I called, had them look up the baffles, and had them made. Another $1000.00.
Wouldn't you know. . . The CAD files baffles for cylinders #2 and #4 were some earlier files I created (well, I hired a CAD person to make the drawings for me) at the beginning of the drawing process. These drawings, somehow, got saved on a disk and handed off to another CAD person for the FAA redline corrections. So, for most of the time I was getting the drawings approved, I was holding drawings I thought were being approved and the second CAD guy was making changes to a different set of drawings. Something similar happened to the oil cooler baffle. Not quite as bad, but, still.
Then, more drama. The #3 baffle was made from a Van's RV6 baffle. My drawings were exact copies. In fact, I made a paper copy and glued it to the Van's and it fit. Turns out, the angle (on the bottom that displaces the upper portion away from the engine) on the Van's part is off by about 3 degrees. This is OK on the Van's install because his right rear baffle is kind of crudely bent into shape; final fit and trim is made by the installer. Unfortunately, the parts I'm having made are exactly how they are drawn. The #3 cylinder baffle won't nest into the right rear light it should. So, bottom line, the 10 #3 baffles and 10 right rear baffles I had made, are wrong.
For the last week I've been driving to the Bay Area to work with the CAD guy at the fabricators and driving to Folsom to work with the CAD guy that made the baffles in the first place. All the drawings were finalized yesterday, Sunday.
Good news is, the cowling is mounted on the plane and it's waiting for baffles.

So, another visit from Mr. Murphy, of Murphy's law.
Awesome looking cowl!
