I thought I would start a new thread regarding my 2+2 build. As many of you know, I have been scratch building this project for a long time now; that's how these things go some times. I feel like I have turned a corner on the project, moving from the "fabrication" stage to the "completion stage"; what ever that may be. My recent posts have shown the completion of my wings and other topics related to my build. I thought it would be easier to just keep everything in one post as I move forward toward first flight. First, some background of where I am at.
As you can see, my wings are done and sitting on a rack allowing me to move them outside as space is needed for other activities. The wings still need fuel tanks and tank covers along with control cables. Although wood, the wings are basically stock Super Cub wings. The flaps use stock Super Cub bell crank and related hardware. The flap handle will likely be between the two front seats but that still needs to be done. The fuselage is basically complete less some final welding. I need to weld in the necessary bushings and such for the control cable pulleys, trim and brakes. I also need to weld in some tabs for the floor and other interior items. The tail feathers are finished and primed in Stewarts Ekopoxy. The rudder is covered and awaiting rib stitching and Ekofill. Ailerons and flaps are in the family room for all to see. I have an engine mount from a PA 12 that I need to repair and reinforce for the O290D2 that I will be using. Why that engine choice? I got the engine from a friend's Pacer when he decided to upgrade to a constant speed prop. I helped pull the engine after properly pickling it for long term storage. I could not turn down the price. A second overhauled O290D2 presented itself to me; again at a great price. I now have two engines. I also have a prop, two carbs, four mags, radios, etc; lots of parts all over the house. This is a long term project; it's all about time and money. I should be in the $25K range when finished, including the second engine. It can be done, it just takes lots of time.
So now what? I have been working on the torque tube for the side-by-sticks. I welded up the assembly and discovered that bushings on the fuselage that I welded up about 4 years ago weren't parallel to each other so out they came and needed to be replaced. This is an example of the type of build this project is. Unlike the quick build projects available to the EAB builders; there is no step-by-step builders manual. I have about 20 pages of prints from Wag Aero along with the many drawings I have printed from Christian's site. That plus lots of digging here at Supercub.org had made this possible. So, I drilled out the bushings, fabricated new ones, jigged everything in place and did some tack welding. I than realized that I needed to remove a gear leg, put the fuselage on it's side, and weld it from the bottom. This worked out pretty easy. A couple pic's ....
With the welding complete, I fitted up the torque tube assembly. Everything fit as it should. I still need to do some honing and polishing to get a lighter feel to the stick but there isn't any binding at all.
Next step will be attaching the left wing for the first time to begin the process of running the cables. I need to make a few pulley supports first and than I'll be ready for the wing. By turning my fuselage toward the garage door I can attach one wing at a time in my garage/shop.
That's where I'm at. I'll try to keep up with this post with my progress and with the many questions still ahead.
Thanks for all the help along the way; I could not have done this with out all the assistance from the great guys here at Supercub.org. I'll keep you posted with progress reports and with many, many more questions.
