Forward Baffles

September 5, 2019 – The never-ending chapter of the baffles continues.

I placed the forward baffles in position. I made the clips that attach these at the bottom onto the left and right inlet ramps.

Looking at these pictures, one question comes to mind. I’m not sure if these baffles need to be trimmed where they go just inboard of the cowl inlet lip, where the cleco clamps are placed. I can’t find any pictures that show this area specifically. It kind of makes sense to me to leave that part there, and run the screws through that. It would only serve to seal that area that much more. Oh well, I’ll figure that out…

Anyway, I drilled the three clips.

One thing I don’t appear to have a picture of is the left ramp support bracket. This bracket attaches to the case just above the starter, and supports the inboard forward end of the left inlet ramp. The way I interpret this, the top holes need to be drilled through the ramp.

They would interfere with the CB-702Q bracket which is on the aft side of the left forward baffle. So I figured out where both of these parts intersect above and below the ramp. This picture shows the area where the support bracket lies under the ramp, and the fastener with the cleco is the common fastener.

I riveted these clips to the forward baffles.

Now I had to deal with the side baffles where they meet the inlet ramps on both sides. The bottom edges of these baffles are supposed to be bent.

Here’s the right side:

And the left:

I thought about just cutting the left side off since I had changes the basic structure with the snorkel, but I decided to incorporate that into the structure.

Here’s the right side after the bend. It looks really bad in this photo, but it really does fit nicely.

…and the left side. I bent it then cut it to fit in the channel where the snorkel attaches. It will be attached when I do the fasteners for the snorkel and filter retainer.

The plans call for a conical gusset on each side to smooth airflow into the baffles. Since the left side has the air filter and its associated structure. I don’t need one there. I made a rough one for the right side. It needs to be cleaned up, but I like it. They call for it to be made from .032″, but I wonder if .025″ would be adequate. It fits the contour of the cowl inlet.

This was one of those days where you get a lot done, but nothing looks different…
