Strut Cuffs

[Hank Jarrett]

Re: Strut Cuffs

If I can get a main (front strut) and small (rear strut) one I will make a drawing. What would be best if it is from a plane that still has the original small size strut tubes.
Someone on this thread said that the outside shapes for them is supposed to be the same and only the inner curve is different as the size of the strut tube increased. That makes sense and I don't know why it didn't dawn on me before except that the ones I have seen so far were all so different on the outside!
If I can get a couple that are original and the same we should know what they really looked like and maybe they will fit better than the ones I have been messing with. I have a pile of cardboard ones in the hangar that don't fit worth squat.
It really doesn't need to be the actual cuffs, a tracing would be fine with the thickness on it. it's a lot cheaper to mail a piece of paper than a couple of pieces of metal that don't want to stay flat. Curling envelopes that set off metal detectors probably freak out the postal employees!
My address is on one of the earlier posts if you guys can mail tracings. I will mail each back a copy of the ones that match the most often and throw in a drawing of the pieces that make up the lower end cuff. THAT one seems to fit well on my plane.

Re: Strut Cuffs

Can someone post a picture showing the attachment points. I can see the outer screw on the plastic one in the previous pics but what is it attaching to and how is the cuff held together. Just seeing it on the plane does little to show how it goes on.

Re: Strut Cuffs

There should be a hole in the channel the strut upper end attaches to. The cuff wraps around the strut and a PK screw goes through the sheet metal ends and into the hole in the channel.
When we pass out copies of the drawings I will get some pictures of the attachment unless someone beats me to it.
I never liked putting a PK screw into a steel channel, not because of damage to the channel, I just don't see why the screw wouldn't ever back out allowing the cuff to fly off. Maybe they do and that is why so many planes don't have the cuffs! It would be pretty easy to use a Tinneman nut and a machine screw. I will look into it.

Hank
will get to air port in next day or so will get some good photos of plastic ones on my ship will see how much work it is to disassemble and trace them to add to the drawing file of cuffs Chuck

Re: Strut Cuffs

Hank I will trace the plastic cuff that Rob sent me as it is almost straight now after sitting under a weight for over a year. Or I could scan it in too if it is small enough to scan in on my standard letter size flat plate scanner. L

Re: Strut Cuffs

Larry,
Best if you mail the tracing since scanners usually distort drawings. Besides, I owe you a compass logo and a drawing of the pre war 4 piece windshield and still don't have your address. The 4 piece may be getting some improvements soon based on some remains of an original one Wally Black found. That will delay the drawings of the old windshield parts a while.
If you mail the tracing be sure to remember to put your return address on it. Hopefully by the time it gets here I may have the windshield drawings.

Re: Strut Cuffs

Well it was a banner night in the Lyons house hold. I have the tracings on light card board and will get them in the mail tomorrow, if my world does not cave in! Rob, these tracings are off your plastic strut cuffs, any idea on vintage?

PS: My return addy will be on these templates when you get them. However I have your email addy and can get it to you anytime.

Re: Strut Cuffs

Does anyone have any pictures of these installed. I see the one bolt in the previous pics but I need a close up pic on how they look on the plane and how they are attached.

Re: Strut Cuffs

Not sure if this helps anybody.
These came with my project.
They're plastic templates but I can't verify fitment.
My plane has a different size strut on each side
I'm sure someone can download these pics & adjust them to size.
The tape measure will give you a guide to sizeing.




Tell me where do you tie down to, when cuffs are installed?

That is a great Question. If its drill a hole in the new sealed strut and install screw... Wow

Re: Strut Cuffs

Again to anyone..how do the cuffs attach to hold firm around the Strut ?

Re: Strut Cuffs

Mine are not attached to the struts. There is a flat metal piece on the
wing bracket that they screw into.

2 screws in the cuff ends hold the shape. one screw attaches to wing attach bracket or clip attached to wing attach bracket holds them on
