Kazoo120,
Yeah the instrument panel is made from Magnesium. To bad you used stripper on it. You'll need to get it SUPER, SUPER clean, don't paint it with Zinc-Chromate either otherwise it will still corrode. Probably an epoxy primer would work best. Or if you feel up to it use the old one as a pattern and use a router and very carefully cut a new panel from aluminum. Just a thought.
Cheers!

Didn't use anything on the inner panel, the paint was like that when I separated the halves. Not sure what had been done to it in years past. It's "chalky" in appearance and feel, not in very good shape...Don't know what tool was used to cut out the altimeter hole for the different adjustment knob, looks like a saw of some type. It's going to take some work or replacement to make it look nice.

Go to the harware store and get the thickest plexiglass they have..3/16" will work but 1/4" would be better. Use this for your template. Use a router and a pattern bit to cut the panel to size and all the instrument holes. Omit the areas you don't want to cut out in the old panel and shape the aeras in the plexi until your satisfied with the way it looks. Use the same technique to cut the aluminum panel using the plexi as your pattern to follow. Make sure you use a sharpe new router bit on the aluminum and move slowly to avoid slipping and cutting an area you don't want. It will look like a factory panel when your done.
Cheers!

You're gonna make me look bad. You're really getting busy! I've been milking the restoration of my 140 for over 7 years now. I for one really appreciate your desire to keep it original. I'm not a total purist, believe me, but I'm all for the KISS principle and for keeping things light. It's a li'l Cessna after all, not a business jet.
I've attached a couple of pictures of what I've been working with/on.
I have a few extra holes in the panel, but nothing hideous.
For what it's worth, I'm sticking to the original fuses. They're cheap, reliable, and simple.
The only modifications I've made are: Electric turn and bank (returning to original) instead of venturi-powered, and a built-in intercom.
Keep up the good work.

You have a blank canvas to work with. I have panel envy! When I first seen your pictures, all I could say was WOW! I do not think I have ever seen one that original! You are very lucky!
I can not take credit for my panel, it is the work of my father. He kept it mostly original. He did add circuit breakers, key start for the O200, and a panel mounted intercom. He also installed the original brown face gauges in their original locations. We even have a stock ashtray and glove box.
Here are some pictures of our panel if you are interested.

My A&P friend Ray and I finished removal of the wiring "Harness" last night. It wasn't really a harness at all, just a group of wires held together by P-Clamps, Adel's, and grommets. One of the wires came right off one of the fuse holder lugs! and there were some rubbed thru wires. I could not melt the old solder with a soldering gun, leaving Ray to suspect they had used silver solder but another Pilot I work with suspects that it was simply very oxidized solder. The wiring was definitely done in-place, by hand, at aircraft assembly, in 1946.
Overall it's simpler than a Ford Model A wiring I think. Dirt simple actually. Once out, I soldered wires back together (had to cut some wires to remove the fuse holders) on the bench to hold and use the old wiring as a pattern. We'll work on specifying a new wiring schematic, to later include radio's and any other items to be added.
Also removed:
-Pull cable for the starter
-Primer and its plumbing
-Voltage regulator
-Magneto switches and wiring
Panel is now completely stripped! (wonder if I technically needed to call in an asbestos Hazmat removal team?)

Back to the disassembly. Dove into the pedal/brake assemblies today, it was the toughest of the cockpit area work with respect to working position and the way things have to come apart. The nuts on the bottom of the clamp blocks were a real pain, got cramps holding the open end wrenches on those. And the nuts/bolts on the brake masters took some work. I have new found respect for the Mechanic's that do this every day!
Also removed the motor mount,,, geez that thing is lightweight, it's amazing to know the motor hangs off of it and all the thrust transmits through it!
And removed:
-Gas/water separator
-Battery box (to make it easier to go down the tunnel)
Getting to where we'll be working the control cable replacements, that's going to be the point of starting re-assembly, the turning point as it were.

Continuing with the fuel selector valve. Had to fabricate some shortened wrenches to get under the panels and get the b nuts loose and off, but overall it wasn't too bad a job. Will research now how to rebuild the valve..

It's been a couple of weeks since any major work days on the project 120. Took some time to go snowmobiling in the Michigan Upper Peninsula, and worked on preparations to sell a race car that I have, to gather more funding for the restoration. I'm working "The List" of tasks on the fuse and looking forward to warmer weather to do some chemical corrosion removal.

Back to work on the 120 project. Have been working the pedal assy and brake master cyl's. I got the master cyl's apart and boy are they simple devices, at least as far as rebuilding. I had been looking for some sort of rebuild "Kit" for them but the reason there isn't such a thing (at least as far as my search went", is because there's only 1 o-ring to replace. AND the one that was in there at 67 years old, looked like new, still rubbery. But replacement is very much in order.
Then onto stripping the paint off of the upper engine cowling, came off very well.
And 16 year old helper Greg spent more time on the floorpan under the rudder pedal assy cleaning, and it's really starting to look good under there!

Had the opportunity to see a Luscombe 8A under restoration in the area locally. It's a 1947 and the owner has had it for some time. It's fully disassembled and in a constructed paint booth, and a little further along than my 120 with respect to fuselage fiishing. Plane is very straight and he has a C90 he's just bought to put in it, and has added a fan powered generator and will be adding an electrical system to it, although still plans to prop the plane for starting I think I unerstood.
It was great to talk to someone who is doing the same type of project. He said my 120 project, "would be perfect, if only it were a Luscombe". :swordfight We had a great discussion and he plans to stop out and see our work.
