IOWA'S 170

[iowa]

also, i believe the notch at the top of my shock panel
was, indeed, there originally!
as shown in this diagram
i think the original compass used this notch to hold
the shock panel in place
what are the odds of finding this original magnetic compass?

I like your result so far Dave. Nice work.

As you still have the center bar, as it looks you found out, it's fairly easy to fab a mount to attache to a longer screw placed through the center bar. This is seen quite often with those who still have the "split" windshield. You would be amazed at the view without that bar or more accurately, how much that bar blocks or interferes with your view.

since my L-4B has 'two' windshield bars,
only one on the 170 doesn't seem bad at all.
i've never ridden in a single piece WS 170
just for info tho,
is it ok to put a one piece into the older 170's?

Dave, all the 170 windshields are actually one piece. The strip in the middle is there to hold the top of the windshield into the fuselage. All 170s without the strip must have another method to hold the windshield and that is done several ways under different STCs. So yes, all models of 170 can have a "one piece" windshield.

Dave, that is a great looking L-48! What is the difference between an L-4 and L-48?

I put a thicker windshield without the center strip (Great Lakes brand) in my 170B in 2010. I wish I had done it decades ago; it’s amazing how much visibility you give up with that 1-inch strip in the way.

i'll check out the 170 windshields at Oshkosh

My L4 is an L-4B
not L-48
L was for liaison
4 meant it was a piper
B was the type of piper L4

i'm very excited that is will be cooler at Oshkosh
we've been running 95+ here in Iowa
cold front moves through today tho

While off subject, like many airplanes, Army Air Corps L-4s had many models which indicated models or improvements, indicated by a letter after the designation. The last I believe was the model H. Dave has a very nice L-4B which he restored, several years ago, that he documented at the Cub forums. You will notice his is not green. This is because his early example of an L-4 was part of a small number of aircraft used for training at Ft. Sill if I recall correctly.

yes, it was # 82 of 100 L-4B's
that went to Fort Sill

Dave,
I saw two 170's at Oshkosh with this same notch cutout. Here's a picture of how the magnetic compass mounts to the panel:

Bottom of compass mount

It rivets onto the main stationary panel bulkhead so the original compass did not "use this notch to hold the shock panel in place." You're right though in thinking this has something to do with the compass mounting on top of the panel as the hole is not shown on the standard panel in figure 40. The notch is there to allow light from the top center bulb on the gyro panel to light up the compass too. Take a look at the highlighted circles below:

Figure 70, Click to Enlarge

Finally, notice item 43 on fig. 76. Cessna calls it a "light conductor". Notice the half-round notch on the bottom of it. My guess is that it slides down through the slot in the main panel cover to sit just above the light bulb there. It was missing on my compass housing. Anyone have one I could duplicate?
