Prior to dis-assembly
Photo One is the project before it was disassembled and moved to the shop in San Antonio. Lace-in panels are prominent. I asked the owner (USMC museum) if I could re-use the current panels, but it appears he wants new ones. The workmanship in this plane is phenomenal, and it will take my best effort to cover this to museum quality. BTW, the slipper fuel tank hangs down a few inches because one machine gun's expended brass chute empties straight down.Photo two is self explanatory. This gem is mounted above the pilot's left shoulder. These planes were mostly based in San Diego. According to various reports, the straight nose F-6's were kept by the Navy, and round engines were the favorite of Marines. The plane was carrier capable.
Photo three is one lace in panel. The 3" fabric tape covers both sides of the panel and it has not been split. That kills the theory of doping on a panel then cutting it out before installing the boot hooks. None-the-less, I still may have to do the job that way because it makes good sense.
HOWEVER this puzzle is really a stumper... read on.Photo Four. Here I peeled some of the fabric back to see if it went under or around the boot hooks. The old fabric (linen) tears right up to the hooks and I'm convinced it goes under them. Besides, how would you punch perfect little holes in the tape for each hook to protrude through?
So now I'm thinking the frame was doped on and taped. Then the holes were made in the fabric, probably at pre-drilled locations in the frame, and finally the hooks were installed and swaged in place by a tiny A&P who crawled into the fuselage.
Or perhaps the fuselage sides were covered, the lace-in panels were doped to to the fuselage, the hooks swaged on while someone could reach in from below or above, and lastly the turtle deck and belly were covered???Photo 5. Here is the reverse side of the lace-in panel. The panel frame is elegant. It is one piece of aluminum which has been stop-drilled and then MOSTLY split down the centerline. The inner frame and outer frame are still attached at the corners as shown and also at the center point of each side. This makes a beautifully straight frame with perfectly parallel edges. I am impressed by both the technique and the craftsmanship.
My next step is to contact a boot hook maker and find out what sorts of tools could be used to set the hooks. This might offer a clue, especially if there is some sort of two piece tool using a set and a buck. Many thanks for your ideas.

I think that the answer might be that they installed the inspection opening framework in the fabric before they covered the fuselage. In '28 they would have been using an envelope with sewed seams on the longerons, so they would have been able to place inspection openings where they wanted them. I've seen original Jenny fabric that had the metal grommet drain openings in the wing installed with no patch, that must've been done before covering, haven't seen an inspection opening done that way, but it's possible. Or perhaps they installed the frame, then cut the fabric from the opening, and then installed the boot hooks reaching the backside through the now open hole. My best guesses...

Andrew, I know what he's talking about, but I'm not clear on the actual install. I think you've done this, so would you mind answering him and ccing me on your reply? Thanks! H.G.

Subject: Help with Lace Panel
I am trying to locate ideas on how to fabricate a lace-on inspection panel. Allow me to introduce myself. My name is Mark Julicher, EAA 605278, also a member of NAFI and a technical counselor and flight advisor, and I have rebuilt several aircraft, mostly fabric. But I'm stumped.
I am replacing the fabric on a 1928 biplane that uses lace-on inspection panels. It is easy to figure out how to build the aluminum framework, but after that it gets dicey. It appears that the framework is applied to the fuselage in the usual manner with dope and fabric, but the boot-lace hooks on the original framework were installed AFTER the framework was doped and taped on. Boot lace hooks are swaged on, so how was that done without access to the back of the panel?
I am in the process of contacting boot hook makers to see how these are swaged on Perhaps I'm barking up the wrong tree and the solution is just dirt simple.... ??
So my question is, is there WW I or 1920's expert I might speak to about how this process is done? Or is this a lost art and I'm on my own?? Any help would be appreciated.
Best regards,
Mark Julicher
