Sliding window

Re: Sliding window

Hi Josh, Not the greatest shot, but gives some idea. The frames still have the flashing screwed to them. The serial # is stamped into one of the window latches. Which would make them circa Jan. 1939.

Re: Sliding window

Thanks, Howard. That helps. Can you describe the method for holding in the "glass?" Is it a channel all the way around or is there a strip that screws in from one side or the other?

Seems like there ought to be a way to find drawings of this, but I don't have a clue as to how to go about it.

Re: Sliding window

Josh,
On Mine, the "glass" (lexan) lays on top of the frame and then the flashing is layed over the lexan , PK screws thru the layers into the frame hold it all together. Make sure the holes in the lexan are a larger diameter than the screw. I'll see if I can put up better pics tomorrow.

Re: Sliding window

Here are some pics of 20442's side window assy. The frame appears to be aluminum square tubing, with the center support cross section being round: Will mic it if you like.

Re: Sliding window

OK, this is strange. My 41 hasn't got the flashing around the outside. The transparency is screwed directly to the frame with some irregular gaps around the edges. I was going to fill the gaps and re-tape and dope, but it makes a LOT more sense that there was flashing around the outside edge. Can anyone with the sheet metal on theirs trace it and post a picture with some dimensions? How thick is the aluminum? How wide?
Funny I never notice the flashing on any of the old pictures.

Re: Sliding window

Hank, I'll trace them and send it to you. They are not perfect. I'd make some from tag board, from the tracings first, to get the corners and hinge clearance gaps better. I'll mic the thickness too. Don't know if this was standard but seems to work nicely. PM your mailing info to me.

Re: Sliding window

Thanks, I figure they are probably made to fit each plane so any tracing will give me the general idea. This will sure be easier than a "custom gap closure" on the doors!
I'll send a PM with the address.
thanks again

Re: Sliding window

Hank--

many thanks! This is exactly what I needed. Thanks for the effort involved.

Re: Sliding window

Guess I'll have to get better with my Al welding skills...

Need to learn how to weld like Kent White.

Thanks again,

Re: Sliding window

Finally got around to welding up the first of my replacement window frames. Many thanks to Mr. Howard Wilson for sending me pictures of his!

Here's what I had next to what I built:

From Taylorcraft

Perspective makes them look different sizes. Have no fear, I fitted the pieces in the frame as I went along. About 1/8" gap all around.

And a goofy little video of the comparative rigidity of the two:



I've still got to make the trim pieces to go over the "glass" and bolt on the hinges. For what it's worth, I used Tin Man's Aerobraze to join the aluminum tubing. I'm still not good at it, but getting better. Somehow my flat aluminum coupons are easier to practice on than the tubes! (Different alloys and different joints-- much cheaper, too!)

Re: Sliding window

Dennis,
I've often wondered if a modification could be made to fuselage just forward of the door. A vent scoop that opens/closes like on the Piper PA22 series would be great. The ventilation in my TriPacer was supurb, and it could be closed off in the winter.

That's what I did, put the NACA scoop on the boot cowl just below my knees
where I can reach it . I do have the sliding window but there wasn't enough
air movement for my liking .

Re: Sliding window

I agree with Forest. I have the buttons on the boot cowl and the sliding windows. The buttons work great. They don't take long to install. Good luck!

Re: Sliding window

In my project plane there are sliding windows. They do not have the metal things to grab onto, nor do they have any sort of channels for the glass to ride in. They look like someone took a door apart and just installed two sheets of Lexan with some felt on each side. This setup works, but the glass doesn't slide very well. It slides, but you have to monkey with it a little. I think if someone were to add another piece of felt, or maybe a thin piece of nylon, between the two pieces of glass, it would slide a lot easier.

I have also seen a very similar setup where someone added a narrow piece of wood with grooves cut in it for the glass to ride in.

Well, I tried making my flashing out of .025 3003, but that seems way too flimsy. I've got some .032 2024T3 and some .050 3003 as well. Any suggestions as to which one would work best?

Do the hinges mount on top of the flashing or underneath?

Thanks,

Josh

Re: Sliding window

Josh, the original didn't have flashing. Just make the window a little oversize to cover the gap around the frame. Also put a thin rubber seal between the frame and the window. If I remember correctly we used countersunk screws for the window. Tom
