Today, the weather in Dallas was PERFECT, so I got out the Harbor Freight soda blaster and worked on the light surface corrosion inside the vertical stabilizer. Only took about 45 minutes and a lot of dust, but the inside looked great after. Later I took it down to the airport and sprayed the inside with Zinc Chromate Primer (after flushing with water and drying of course).
I also “Dry fit” the OLD cargo floor and front wall to evaluate using aluminum to replace each and the use of Oratex as a side wall covering. I came to the conclusion that I may want to go with the original cargo canvas material, because if I cover the entire cargo area with Oratex, then getting into the aft fuselage may be difficult. I may use a local upholstery company to remake the cargo envelope.
I watched a video on YouTube about using this material used to protect new floors as a great thickness of cardboard to make patterns. Well I gout out my floorboards and made patterns. I plan this week to go to a local meta sales store and see if I can buy aluminum plate that is waste from drop cuts.
Considering everything from diamond plate, to smooth aluminum with anti skid material. Also considering either powder coating or cadmium plating. Stay tuned.
Tonight I added some new Brake lines. The old ones looked original and very brittle. The old ones had a funky fitting to go through a bulkhead, but I replaced them with a standard AN832-4D union and nut which works much better and allows for standard fittings on the lines.
I was out at the hangar tonight, working on Brake master cylinders and the Cleveland calipers. I put the fuselage out of the hangar in the grass so I could have more room to work. Well the Sun set was nice and I thought I would take a Glamour picture.
As she sits here, she has all new control cables installed with all new Pulleys. Also rebuild control column and Dual brake / rudder pedals.
Working on Floorboards and Brake lines now, next will be 1/2″ fuel lines and selector.
SO if you have been following my posts, I’m interested in the Oratex product which is a pre-pigmented STC’d covering that once you install, you are DONE.
The value is lighter weight, stronger, but mostly NO PAINTING, which means I don’t have to move the wings and fuslage to a paint booth and pay someone to paint.
Is it worth it? Well that is a question I’m going to struggle with. The quote from Air Tech including paint, is abut $3800. The Oratex quote is about $8700. Two times the cost. Is that work not paying someone to paint?
I mean I’m still going to have to paint all the metal parts, so there will be paint costs, but not the BIG pieces like wings and fuslage.
