So close, so close and yet so far...

Re: So close, so close and yet so far...
If I could afford a new Cessna I'd be flying an RV-10.
And I'd take the saved money and buy a 140, a 170, a 195, a Pitts Special and a few Piper Cubs..

Re: So close, so close and yet so far...
Just an update....
I pulled the wing on Friday. We knew before taking the plane apart that the front right bulkhead bracket was corroded (had a blister 1cmx1.5cm). It was removed to see if it was infecting the spar carry through. Luckily, the spar looks great, inside and out. Now I just have to replace the bracket with a replacement. I have a question: Do all solid rivets have to be replaced with solid rivets or can alternatives be used?
Thanks, Shawn

You need to use a Cherrymax because one end of a solid rivet cannot be accessed inside the door post? You can replace a solid rivet with a variety of fasteners but generally rivets should be replaced with the same type of rivets if possible.
Blind fastener selection and hole preparation are key aspects to a successful substitution of a solid with a blind.

I agree, that's what I did....................and it only took 30 years!spduffee wrote:Even if I could pay for a new Cessna, and despite all of my complaining, I'd still buy a classic 170/ 180/ 195. There's no comparison.

Re: So close, so close and yet so far...
I removed the aft bulkhead today and was searching for replacement parts. The part number of course is 0512108-3. I remember seeing a posting about someone whose mechanic supposedly fabricated a new one and I believe someone said it was next to impossible, due to the continuous tight radius at the bottom. Here is a picture of mine, that I removed today. Its lower small radius is segmented. Does anyone have a photo of an original piece that is not segmented? I think I read someone saying that a segmented lower portion is a sign of an aftermarket homemade, and illegal?
Does anyone happen to have a spare laying around anywhere?
Thank you,
Shawn

Re: So close, so close and yet so far...
Shawn, if you are unable to find a new one, New Old Stock(NOS) let me know and I will make you one. I am really busy but I will fabricate one for you. Please try to get NOS first and exhaust all options but I will make sure you keep her flying. Doug

Thank you, Doug! I'll keep looking around for a ready-made and definitely get back to you if I don't find one.

Re: So close, so close and yet so far...
Shawn that part looks suspiciously like a true Cessna part.
At some point after you have found the path your going to take, ie have a new or good part in hand, it would be great to flatten (if possible) and get an accurate tracing of that part.
It is only a matter of time until manufacturing parts will be the only way and the Association needs to start collecting as many details about these parts as possible.

Re: So close, so close and yet so far...
Thanks Bruce. I am actually working on reproducing the unit in Autocad. Hopefully no one will notice that i am not working on floor plans. If so, i will simply say it's a custom beam seat pocket. I will share the results with the team.

Re: So close, so close and yet so far...
Flattening and tracing the part might not work very well as the aluminum will stretch during the flattening process.
Making a CAD of the drawing is closer but be sure to calculate the extra material needed for the bend radius.
Also, consider making a CAD of the inside of the part to possibly make a form for hydro-forming.

Re: So close, so close and yet so far...
Here's a link to the post you referred to. There is a photo there of the bulkhead which is not segmented. If you can't find a replacement bulkhead you might try calling Chris at Del-Air to hydroform the part (assuming Del-Air is still in business).spduffee wrote:I removed the aft bulkhead today and was searching for replacement parts.

Re: So close, so close and yet so far...
Yea! the wing is back on!
I got a new bulkhead from Corvalis Aero Services (Warren Ruck) in Oregon. They may have some odds and ends from 170s.
