Starting Pitts exhaust tunnel work
The new Wolf Pitts gear will allow the exhaust to be tucked up under the belly of the Pitts a little better. Part of making this work requires building an exhaust tunnel. Today I started taking a look at what will be involved. There is a steel former that located the front of the forward belly pan. This will need to be replaced with a new piece that has the cutout and new profile for the tunnel.
I taped a couple of welding rods in place to roughly represent the new edges of the tunnel. This will help me start thinking about the details and get a better picture of what the end result should look like. First, I'll cut out the old former. Then I'll get some poster board to start mocking up the sheet metal. Once I've got a good layout and plan, I'll make the new former and start bending some sheet metal. I'm guessing that this will turn into a fair amount of work to really get it right. We'll see soon enough.
Here's a picture of the area looking back from the bottom of the firewall.
