Baggage Sling

[Rex Havis]

I need some information or pictures of the wooden frame that holds the canvus baggage sling. I have three wooden pieces that are routed out to fit around the metal framing. Two of the pieces are short, when they are placed end to end, they are the same length as the third piece. I Thank these pieces go on each side with a cross piece from side to side attached to the side pieces to form the frame. The aircraft is a 1940 Bl-65. Any help will be appreciated. Thanks Rex

Re: Baggage Sling

Only 1 piece of wood for the seat sling. It is attached at the top to the cross tube by wrapping and lacing. In the bottom corner it is laced to the bird cage (metal tube with brackets for seat belts and wires on the ends to attach to the airframe). The front tacks or staples to a wooden bar which is the wrapped to adjust tightness of the sling. This is held in place with 4 AN3 bolts with large area washers to the 4 extensions forward of the tube that will be under your legs. Tom

Re: Baggage Sling

Are we talking baggage sling or seat sling? I think the question was for the baggage sling where there are two short pieces of wood going back from the upper seat back tube (with the wood cross piece Tom was talking about). These pieces of wood are attached to the baggage sling rear wood piece with some metal angle clips. There should also be a wood frame behind the cross piece that support the hat shelf and the aft edge is where you attach the headliner.
In the picture the short piece is under the fabric below the "D" window and the long piece is on the left of the sling. The piece of wood Tom was talking about is on the right or the sling. To the left of the top of the sling you can see the hat shelf.

Found this earlier picture with the headliner out.

Re: Baggage Sling

My bad! I saw sling and made the jump to seat. Sorry!
Like Hank's pictures show. 2 short pieces on the sides extending back from the top of the seat, and a cross piece at the rear. The sling attaches on the sides and the rear to the wood. The front should go over the the top of the seat sling and be stiched or glued.

Re: Baggage Sling

Thanks for the help. I now understand how the wooden frame is assembled.
Would either of you happen to have some pictures of the wooden cross member that picks up the bottom strangers and forms the opening around the bungee cards. None of these parts were with the aircraft, and I'm having a problem with the shape of the cross member at the gear attachment point. There are a lot of pictures of the bungee cord opening but none show the area under the frame at the gear attachment point. Thanks Rex

Re: Baggage Sling

Thanks Everyone, I thank I now understand both the baggage and frame work around the bungee cards. Its nice to have a group of knowledgeable people to ask questions.

Re: Seat Sling, was Baggage Sling

Only 1 piece of wood for the seat sling. It is attached at the top to the cross tube by wrapping and lacing. In the bottom corner it is laced to the bird cage (metal tube with brackets for seat belts and wires on the ends to attach to the airframe). The front tacks or staples to a wooden bar which is the wrapped to adjust tightness of the sling. This is held in place with 4 AN3 bolts with large area washers to the 4 extensions forward of the tube that will be under your legs. Tom

To Tom and Whomever It May Concern: Thanks for this. And I may be about to make history, albeit a small and insignificant part. To wit:

I have the four AN3 bolts with sufficient grip length to secure the seat sling bar as well as the flat washers and stop nuts required here. The problem: the holes in the extensions just are too tight for them. This looks like it will be the first time these have ever been installed in my '41. ...Is that possible? Was maybe a different bolt used by then?

Worse - the tubing extension brackets in the frame are threaded, and when the sling bar was removed on last annual it had (barely) been held in place using WOOD SCREWS (!) driven in from below.They just do fit the steel threads (likely crossed) very tightly but don't make any meaningful contact with the holes through the wood- acting only as pegs when in place.(!) (...And I had been flying it like that!)

... As usual I had to discover the discrepancy myself. - Nary a word from the crew working on it.

So thinking I may have to ream out these threaded holes to be able to push the AN bolts through... I copied the 1940 AD notice specifying the type AN bolts and as far as I can tell they translate into AN3. So, then do I need a field approval or 337 before proceeding? Anyone know? The AN bolts are technically original equipment. Or at least hardware. But that much more so are the threaded extensions original. So -

MS 27039 /-C machine screws do come with narrower shanks in the right grip length. But (so far as I know) that wouldn't be using the specified equipment. And I have no earthly idea why holes were threaded?!

My mechs keep referring me to you guys.

They don't tell me not to jump threads though. Maybe not... but since this did start here -

Re: Baggage Sling

The 4 extensions that the front bar of the seat sling attaches to had a threaded insert that the 4 AN3 bolts screwed into. Quite often these are stripped out or turn in place and are removed to be replaced with a lock nut inserted from the bottom side of the "C" channel. Tom

Re: Baggage Sling

OK. Thanks for that. I don't think these extensions are stripped but could be stressed some. So all I need now is to find a set of these threaded inserts.

I have no pics in any of the literature of them. Any idea where to locate a set?

Re: Baggage Sling

Hi Bill,

Don't know if you've seen this. But look at the nut they reference in the S.B. 24 dwg. This is the way mine are in the '39. No threads in the tubes.... h

Re: Baggage Sling

Yes, Howard,

I'd seen it here but have been looking all over and was unable to find it. (Ed.: I referred to it as an AD by mistake. Meant SB.)
My new computer doesn't like my old printer so I had carefully copied it by hand and filed it with my a/c logs. But I am saving this to disk for future ref.

Thanks!

(BTW did you ever find those Al head gaskets? Think I still have a used one but not sure if it's serviceable. Let me know.)
