Rear window frames

[Skyboy]

I need a set of rear window frames for a 46 BC12 that came from the factory as a delux model but somewhere along the line someone removed them. Doing a SLOW rebuild.

Thanks, Mike

Hello Mike, and welcome to the Forum.

Are you talking about the rear window frames as in the photo below? (White, presssed aluminium in my picture)? Mine are from a 46 BC12D, but in reality are probably from a BC12 or earlier...I know not.

I don't have a set spare, but the picture might help you (or others) identify the part, good luck!

Re: Rear window frames

If you are looking for the frames in Rob's photo (those are the standard frames from right after the war) I have drawings of them. The only hard part of making them is pressing in the half round groove, but it can be done with a grooved piece of MDH and a rounded dowel.
I also have drawings of the pre war wood frames that are smaller.

Hank, I have access to a molded rubber press, if we can get a form made, I can stamp them out. Tim

That would be a part that would find it self a home by many, without any commitment to be a part of building it I would certainly want one.

Re: Rear window frames

The blanks are common but you need two forms. They are mirror images of each other. I have the ones for the 45 as well as the drawings if you want to set something up to make them. Drop me a message at hjarrett2 at cox dot net.

Re: Rear window frames

Hank, do the drawings require the part to be heat treated? What alloy is called for in the material for the parts?

Re: Rear window frames

YES... The white frames in the photo is the one I'm looking for. Looks like I'll be making a set as the replies sound as if I could get chicken teeth easier. I do have a friend at DWU that is doing a rebuild and this looks like the way that I'll have to get my pattern, just hoped someone out there had a set.
Thanks for the feedback!!!!

Re: Rear window frames

Mike,

There was a guy in Texas who was selling parts from a plane he was parting out a few months back. Put a request out there on Barnstormers for starters.

Re: Rear window frames

Did anyone check to see if Univair has this part?

Re: Rear window frames

The frames aren't heat treated and are made from fairly soft aluminum. I would think considering the loads you could use almost any of the available aluminum's. The metal is about as stiff as what is in a cowl and feels softer than rib material, but I don't have a hardness tester to check. Kind of has the bending resistance of the stuff they use for gutters (at the same thickness).

Re: Rear window frames

Hank, would it be possible to make your own wood ones the size and shape you want?

Re: Rear window frames

Aeronca uses wood frames. Try to get approval

Re: Rear window frames

The pre-war planes with "D" windows had wood frames. They were slightly smaller than the post war ones and MUCH smaller than the big rectangular late model ones. I have drawings for the wood ones too. I made the wood ones for my 41 and they came out fine. A little "fiddly" to mount compared to the metal ones but I think easier to cover around and attach the head linner.

Re: Rear window frames

Hank, how would I buy the drawings from you for the rear D windows made of wood?
