Engine mount for dynafocal engine.

So the airplane will eventually need an engine bolted to the front of it to give it the power to burn money.  The project came with a "run-out" engine that had a dynafocal type mount.  It was time to build that to the landing gear mount.  First I fit it to the engine to look at where clearance needed to be built in.  Then I made a template of the front of the plane and the landing gear mount.  I then made a small jig from all thread and angle iron to hold the dynafocal ring in space with the correct clearance away from the firewall.  I leveled the false firewall jig, the jig that holds the ring, measured the thrust line to the jig, lined everything up where it should be, and started cutting some tubes.

Adding some firewall framework and stuff

So to eliminate the square area of the forward fuselage at the firewall, I needed to add some framework to the front of the airplane to give it more "shape".  At the bottom this will allow clearance for the exhaust to clear out of the fuselage and not be hanging out in the breeze.  It creates a "tunnel" in this regard.  At the top of the firewall area I added a curved piece of steel to give a slightly rounded or curved shape to the front.  This will allow the cowling to fit better, and overall look a little better than just being a box. I also had to finish building the landing gear mount for the the front of the plane and eventually a motor mount. After completing this I worked on creating a firewall out of some stainless steel.
