Default Canopy frame

Arlie,

Could you post some photos/details of how you did your canopy frame please? Was the canopy from Todd?

Thanks

Chris

Lightbulb Repaired damaged rib..... the right way finally

When I dropped my wing out of the jig last month while riveting on the outboard aileron mount, I am fortunate that the bottom outboard skin was off. This allowed the main spar to hit me in the back of the head, which lessened the impact of aileron mount hitting the concrete. Nevertheless, the tib rib suffered compression failure at a flute. Here is the initial damage:



When contemplating repairs, I decided I really didn't want to drill out close to 40 rivets, including 27 in the top skin, and 8-9 in the main spar web. So, I removed the damaged section, and was going to use a portion of an extra rib as a scab, and make a structural patch. After starting this process, I didn't like the way it was going to turn out. Best pic I have is this one again from Sunday with Paul in the background. Pretty easy to see the big hole, as mentioned earlier this week:



So today, I came home from work, and was tired of looking at it. I drilled out all those rivets, (It was a PITA to drill out the universal rivets in the spar web, due to the curvature of the wing) cleaned everything up, fluted and marked centerlines on new rib, and drilled it to the wing. Other than primer, this looks MUCH better:



Now the usual deburr, dimple, prime and rivet......more to come.

Gregg

Default fuel lines done

I finished up the internal fuel line plumbing. Getting closer to moving to the airport. One question? I decided to go with the softer 3003 3/8 aluminum fuel line. How many use this grade of tubing and does it hold up? I've read mixed reviews. Some good, some bad.

Default Old vs. New

This is what the same compartment looked like a year ago before we started the restoration. Keep in mind that this was a flying aircraft before we bought it.

Looks GREAT Arlie! What did you use to clean off the old dirt/gunk without removing the paint? Or did you repaint the interior?

When we got the plane back to Texas it was completely disassembled, down to the basic airframe. it was then stripped of paint and steam cleaned. Yes, the interior was primed and re-painted. The sides had some kind of contact cement that was a nightmare to get off. I found "GOOF-OFF" to be the best solvent for getting all the grime that the pressure washer couldn't remove.

Default Something easy for a change...


Well, the -4 instructions say that the flap is perhaps the easiest to build of the control surfaces. I have had this RH flap drilled and clecoed together for quite a while, but then got busy working on other parts. I only had a little while to work this evening, so I thought I would get back on the flap. (I need it on the wing NOW to fit the flap brace)

Tonight I took everything apart, deburred every piece, scuffed and dimpled the ribs. Compared to the parts I have been working on, finishing this flap will be well, easy.

Getting closer every day to packing the wings away and starting the canoe.

Gregg

Default It's alive

We are finally finished with all the wiring, except for hooking up the engine monitor stuff, (EGT,CHT, ALT). Everything else is up and running. The GRT was fired up and the radio checked. All the buttons on the stick were also checked and they all worked as advertised. All that's left is re-sealing the tanks, stabbing the wings, re-working the cowl, a little fiberglassing, and of course, a killer paint job.

Default Wings are getting ever closer....

Today I took off work to capitalize on the nice WX. I got a LOT done, and added to my build log. (signature)
I completed the whole right flap assembly today, and lots of misc. tasks that needed dealt with.

It took a while, but here is my flap hinge pin retainer. I would like to take credit for this, but honestly I shamelessly copied it from someone else.

Bottom skins about to go on for good. Then start on the wingtips....
