building 6 j-3 metal structures

[osvaldosurf]

Good morning everyone, it took me a long time to post the construction of these 6 structures, I wish I had posted them from the beginning. These photos below are of the torque tube and its installation in the structure.and also the beginning of the construction of the stick. I hope you like it and comment. visit my (aero maceio) youtube channel. There I have many cad-3d models. hug

Nice, do you have photos of forming the risers?

The vertical part that the stick stub bolts to. The half round part.

I really wish I could talk about how I did it. But I can tell you that I spent two weeks thinking about how I would do this and in the end I was almost giving up, so I slept and woke up in the morning with the solution. I was already in the warehouse at 8 am and applied the idea to a test piece and it worked.

Here are some more photos from my archives. These are photos of some parts of the landing gear. obs. There is an error in the folded plate that holds the fabric on the landing gear leg, but it is already being corrected.

Good morning friends of the forum. I'm happy to share the photos of the stick, this piece gave me a lot of work to do. a piece that has a high level of precision and no errors. The part worked perfectly on the torque tube. no gaps. youtube channel AERO MACEIO. hug

curious what the measurement is in your bottom picture from the center of the pivot bolt down to the center of the hole where the bolt goes through where the cable connects?

more pieces coming out of the oven. We have the stick complete and installed in the structure. We also have the bellcrank almost ready, all that remains is to use the reamer to correct the internal holes. Also check out my YouTube channel AERO MACEIO.Just remember that these screws on the parts are not aeronautical. When aircraft are permanently assembled, these screws will be discarded.

here are some photos of how I installed the bearing that holds the bellcrank

I made a template for installing the bushings that hold the gas tank. and some more photos of the plates that hold the floor and pedals.

I'm finishing making the j-3's lower door, I confess that this is one of the most difficult parts to build. lots of small details.

Hi Tempdoug, these structures are no longer with me. I sent them to the owners. They traveled 2,500 km by truck from my city, Maceio, to São Paulo. I believe the owners will not post photos or images of the completion of the construction. Here in Brazil, there are many people who are rooting for everything to go wrong and there is a lot of jealousy, so they prefer not to show what they are doing. Unlike me, I like to put everything I am doing on the internet.
