S/B M20-208 has been complied with. We plan to tackle the interior next, that will be a good opportunity to inspect the tubing, remove the surface corrosion and apply some primer before continuing. In the meanwhile, Corrosion-X it is.

Good company to work with.

Thanks- you suggested that we "treat" the rust spots in the tubing, and I was asking about how you would do that. My question was, should I just wipe on some CorrosionX and be done with it?

We're done. Mostly the old sealant came off by pulling at corners and scraping with fingernails. That photo above shows the new window installed.

Suggest a method? CorrosionX?

Well we got the left-hand side window installed this past weekend. At the pace my co-pilot and I work, it takes most of a weekend to replace one window. I'll post our checklist items assembled from the advice received from MS members. Thanks to all who helped us figure out how to do this! As the photo shows, the new window (SG+UV) is reeeeealy nice. Can't wait to take her for a test flight.

Nope. Ace Hardware is about as good as it gets in T-Town. I went ahead and ordered 5/8" long #4 SS screws from Aircraft Spruce. I'll put a couple of nuts on then cut them to length with a Dremel.

My friendly local A&P suddenly passed away earlier this year, and I have not made the acquaintance of another...

If I needed a football player, that could be found in Tuscaloosa, Alabama. 100-degree flat head stainless MS24693-C2 machine screws, rare as hens teeth.

Yeah, I thought about that. Maybe that is the way to go. Buy 1/2" so I'll have plenty of room to clamp the non-head end in a vice and Dremel them down to length with a nut on to repair the thread. <whinge>Just, UGH. I'd rather not have to do that! </whinge>

Yeah, I just looked- they sell them in lots of 5000 for about $200. Don't see anyone selling them by ones and twos.

Okay- got your attention. Mind out of the gutter. I bought a pair of Orion 650 wingtip nav/strobes recently for a good price. While cleaning them up this past weekend, I noticed that one of them is missing an internal mounting screw, which is a MS24693-C2 (see #6 below). Of course Aircraft Spruce doesn't stock it. Anybody know of a good source? Thx.

That is an idea, but my day job involves working in a native linux environment. I've gotten used to being antiquated. That's why I fly a 1967 airplane!!!

I agree with @steingar. Plus, the prior owner of my a/c, who is also a CFII, taught me in the pre-takeoff checklist to always push out on the upper portion of the door to verify that the upper latch is caught.

My '67C has an upper latch that looks just like yours in that first photo. It has a little hook on the end that grabs a retainer and holds the top of the door in place. I've only owned this a/c for 1-1/2 years, so I don't know its history. The logs don't say anything about the addition of an upper door latch. I cannot imagine the door would seal at all without an upper latch, given that the cabin is slighly pressurized compared to the curved free stream around the cabin.

Your upper latch is not catching.

I vote dimples. All inspection plates on our '67C are dimpled.

There are obvious signs of wandering screws that scratched the plate around those two holes during past interior installs. The plate is oversized- it could be made smaller and sharper.

O. M. G.

I've got VirtualBox. Any way to get a Mac running in a VM? My day-to-day computer and laptop both run linux. I have a Windoze box to run X-Plane, and to download/install Garmin updates. I really don't want another box laying around for just one app

The Accutrak II in our '67C is switchable between the output of two CDI's- one on the Garmin 430W, and the second on the KX155 NAV receiver. When connected to the Garmin, it follows a magenta line really well, automatically adjusting for the crosswind, it does what is needed to keep the needle centered. Given the wobbly nature of some VOR signals it is not as solid when driven by the KX155. While not approved for approaches, it is a true 1-axis enroute autopilot; when engaged all I have to do is maintain altitude with tiny trim adjustments. I'd love to add Brittain altitude hold, but it seems that parts for that system are exceedingly rare.

Landing is easy- every flight is guaranteed to land. Not dying while trying requires some skill.

Too old. Probably already sired some kids. In fact one would think it would be incredibly unlikely that a couple of guys who lived to be in their late '40's would try such a thing. It is amazing they made it to that age?? Usually this kind of thing is the domain of the early 20-somethings or late teens.

This is a great point- well said. The wing sweep angle of a surface is defined as that angle formed by the longitudinal axis of the aircraft and the 25% chord line of the surface. By that definition, both the wings and vertical stabilizer on a M20 are swept forward.
