Now being able to easily lift the fuse off the ground, I could remove the wheels and landing gear struts. Had to put some weight on the tail for a bit until I got the struts off. The wheels came off no problem, I can see what I've read about the clips on the original Goodyear brakes. Then I removed the 2 bolts holding the wedges on each side, and the brake lines and foot step, then tapped the landing gear front-to-back with a larger rubber mallet until the main mounting bolts loosened and could be pulled out. These baby's are heavier than I thought, sort of surprised me.

Now with the landing gear and tail finally removed, I can get to the real goal of the Chirstmas break, to see how much the aluminum skins will polish. I bought the Nuvite materials and some compounding pads etc, and it's a lot of reading before you begin. I started polishing some areas and saw that I needed to sand some of the raised deposits first. The buffing compounds can't remove everything I seem to realize. There's no deep pitting at all on the surfaces, once the dirt and light corrosion are removed. I've buffed some areas and it's looking positive at this point, the goal is not to have to paint if I can rework the metal. It's as much work as reputed,,,,

Worked on windshield removal yesterday, with help from an A&P I work with. Want to remove the windshield for ease of cleanup and repainting etc,. It was installed new in 1967, just before the plane was stored for many years, so the shield is very clean and clear. Has lots of "putty" on the lower strip, so it's slow going for removal. Plan to pull the lower inner strip as well, to reseal under it. a few more hours and should have it out.

Wndshield is out, just needed to clean off some more of the old glue that was still around the lower inner strip. Had to drill the 2 larger rivets at the ends on the lower inner strip, to remove it. Used a heat gun on low and plastic scraper to carefully clean the black sealer off, and then thinner to remove the final traces. Clean now and can be prepped for paint when the time comes. Interestingly this plane has a "maroon" dash and interior, this seems to be in deference to the parts manual color charts, that list the 1946 planes as having red interior the same as the exterior striping. There's a patch of the maroon color under the ID plate, that is still as original as I have found on the plane, I may see if a paint dealer will bring out a color gauge to match the shade.

Built a smaller/low holding fixture now, to be better able to work on the top of the fuse. I must like making fixtures,,, but they're easy and I still have a bunch of 2X4's left over from a pole building project this past summer.... I'm spending alot of time working on the metal surfaces, it's slow work. Began stripping the old paint and numbers off this weekend as well.

Continued working on cleaning of the fuselage. Only had one evening to work on it this week. There's a light layer of surface corrosion or scaling on the fuse, and I've been working it with Scotchbrite and superfine aluminum oxide paper. It's a SLOW and incomplete process so have been wondering about other chemical methods of removal. I live close to the Kalamazoo AirZoo up this way, and have sent them a note asking about expertise in aluminum restoration, since they restore aircraft for their museum collection. Will await their return note. The Nuvite compounding is not acting the way the websites describe, I need some further expertise on this part of the restoration,,,,

After quire abit of review we've decided to paint the aircraft. Lots of input from knowledgable sources, and this seems to be the best route in consideration of protecting the metals going forward. I still think to paint it silver and put the factory Cessna striping back on. Should be nice when finished, I can paint it at my shop, we've painted many racecars in the past. Jeff Tourt has offered advice so far, which is great after looking at his fantastic work. It'll be awhile now before we'll do more work on any finishing prep, so onto other fuse work.

So it was on to other disassembly! I've been wanting to get under the cowl and remove the gauge panel, cables, old insulation, etc, for somtime now. I fashioned a raised head-support in the footwell to make it easier to work under it (without neck cramps), and put some old boat cushions in the seat pockets and then cardboard over all that to lay on. It's quite comfortable to lay under there to work. I brought a pair of old slippers out to wear when I'm scooting around inside. Don't real A&P's wear slippers when working under aircraft gauge panels? Wouldn't see why not. Although maybe the other A&P's would laugh at them...... I don't care, they're comfortable.

I'd like to spec out the control panel for the 120. Meaning what panel gauges and other items will be installed, as we restore the airplane. I sort of have a goal to keep the panel as original as possible, adding gauges that might have been factory options in the slots that are open, and adding anything that's necessary to the utility of using the airplane, with as minimal impact (to the original layout, and weight) as possible.
I think that I would like to consider:
Gauges:
1. Renew or replace the altimeter. Refurb the original or get another unit? New? used? Gauge looks to have been replaced at some point, it's a "Square D" altimeter.
2. Renew or replace the airspeed indicator. Refurb the original or get another unit? New? used?
3. Renew or replace the Tachometer. Refurb the original or get another unit? New? used?
4. Add a rate of climb/descent gauge? What make/model? (in extra panel opening not currently being used)
5. Add a turn and bank indicator? What make/model? (in extra panel opening not currently being used)
6. Add Attitude indicator? Make/model/size/features/mount/approx cost/source?
7. Add Electric Compass? or other gauge, in smaller opening not being used? Make/model/size/features/mount/approx cost/source?
8. Add time clock?
Avionics:
9. Add Nav/Com? Make/model/size/features desired/mount/approx cost/source/new/used/antenna?
10. Add Transponder? Make/model/size/features/mount/approx cost/source/new/used/antenna?
11. Add GPS? Make/model/size/features/rolling map/ADS-B/panel mount/upper dash mount/Ipad knee unit/approx cost/source?
Other cockpit or fuselage related items:
12. Keep Fuses or Add circuit breakers? Make/model/approx cost?
13. Add Intercom! Definitely want this. Make/model/approx cost?
14. Add Strobes? Make/model/size/features/mount/approx cost/source?
15. Add ELT(mandatory). Make/model/size/features/mount/approx cost/source/antenna?
16. Add EGT/CHT gauge? Make/model/size/features/mount/approx cost/source?
17. Add IGN key? or Pushbutton?
17a. Assuming we Add updated starter with solenoid... To replace the pull handle type starter.
18. Fuel select valve? Renew existing? or Add new with L/R/Both/Off selections? or Add new with existing L/R/Off selections? STC item.
19. Landing light. Add in wing? (fixed type, not the electrically retracting one) per STC.
20. Add Manifold vacuum gauge?
21. Add Hobb's meter?
22. Add Other gauges or Avionics? Suggestions for other items? Center of console is possibly open for another cutout.
For reference, the existing layout includes:
(Gauges)
-Altimeter
-Airspeed
-Oil pssr
-Oil temp
-Tach
-Ammeter
-Compass (floating)
(Switches)
-Master electrical (switch)
-Mag (2 switches)
-Landing light (switch)
-Nav lights (switch)
(Pull cables)
-Carb heat
-Cabin heat (laughable I've heard)
-Brake lock (Parking/Brake lock)
-Pull start
(Other)
-Primer
Lots of possibilities here, in general people want me to leave the panel as original as possible, which does seem like a good goal.
