Scott, on my plans page 22 bottom center just above the v strut bracket it shows .032, but it does not show thickness for the pieces on the axle tube where it bolts to the 5/8 x .035 tube coming from the v strut down to axle tube [ top right corner page 22 ] These pieces of flat stock are welded to the end of the 3/4 x .062 axle tube. I have looked at these plans for years and had not noticed this. The brackets for the wing struts are .090 .:emoji_u1f601:

Ok, now I see “ what is being talked about”  and the dimension call out.    The loading at this  center point with a call out of .032” is so much different than the landing gear piece that holds both wing strut and landing gear Vee strut.   it is the later that I thought the thread was about. And that is clearly call out on page 26.

That being said, I don’t think anyone has argued or stated that this center  piece (lower Vee strut web) needs to be .090” or is called out to be this.

cheers
Scott

Must have been a change in later sets

Hi Tom
 The boss used, both letters and numbers, but don’t know what he started with, (and probably won’t)

But I have XL-A14     I didn’t go down to the plans room to see what the Original eagle plans number is, but not super early like the XL plans I have.

cheers
Scott
I don’t mind changes a bit, as long as I know where to go and see what was changed and when, in accordance to plans number. In general, when  I sell a set of supplemental plans,  if there is a change, I show both ways… mostly to show why the change as well  as how things work with the change.  Or post to the forum for all to see.  But that is different for all providers.

Mine also is 0.32" on page 22, in my plans the page 26 is the wing strut plates and are 0.09". But for the Vee Struts plainly says 0.32" at connection point for the plate.

But as I stated above I will be reinforcing it, When in doubt make it stronger.

I have plan set #XL- A-05 and B-40. Both sets show .032 for the v strut plates.

Just so you don't think I'm off my meds
or on some, I will attempt to post an attachment of my drawing

Let's remember the original question of this thread was what is the thickness of the reinforcing sleeves on the strut tubes.
well if your going over a 5/8 tube a 3/4 -0.062 would fit on the numbers
perhaps a 3/4 - 0.058 would be a little friendlier.
You should have a scrap piece left over from your axle tubes.

Well, that wasn't correct.
The original question
 related to the tabs at the end of the axle tube.
Leonards answer will be forthcoming
But if you add a piece of .058 over a .035 on your strut tubes you end up with .093 of metal 
I think I would like to match it. 
if the strength is needed in one piece it should be there on the other

What metal thickness is used for the tabs used to attach the shock struts to the axle tubes?  I currently have tacked in place .032 4130 as noted for the V-strut bracket used to attach the top of the shock strut.  I want to make sure this is correct before finish welding.  Thanks



On my plans set # 149 for the LEU (not LEXL) purchased in 1998 on pages 13 and 14 the tab thickness for axle tube is called out as 1/8 inch steel so that is what I used on my LEXL.

Builders  The metal on the v struts should be .062 not .032    Leonard

I built mine to plans (.032) and have nearly 30 hours on my XL with no issues. I must have over 60 take offs and landings with several not so soft landings. I do remember when I was building that the metal seemed a bit thin, but it seems to be holding up so far. 

Looks like I will need to weld on a little extra support when I get some time

Hi Nate, did you use .032 for the tabs welded to the axle tubes?

I agree I also thought the plan spec. thickness was light but after lots of landings good and bad I think it is safe. Maybe something to do later when I have it apart to repaint. Keep you speed up on landing.
