Is the material list for the XL on file somewhere on the forum. I am waiting for my plans to arrive but would like to place an order tomorrow for material to make wing ribs. I have the plans for a regular LE but understand I will need more because of the longer wing.

Thanks Steve. I have the cad drawings from Scott in Iowa so that allowed me to get the rib jig all set up and ready. I just modified my old airbike jig to match the new cad drawing. The ribs are very close to being the same.

Double check length of 5/8" and 1/2" round tubing. I believe you will find there is to much 1/2" and not enough 5/8"
-
Will do, Maybe the newest plans will have that corrected if it is wrong. Thanks for the heads up.
-
The material list doesn't seem to have enough .020 aluminum sheet. All the ribs and gussets for the tail from one sheet of 20" X 24"? I haven't laid anything out yet but some of the ribs are over 30". Anyone know how much you actually need?
-
C-77 was published in July 2013, it's still 1 ea 20" x 24" .020
That first inboard brace on the horizontal stab looks like its 36" long too.
I do see the sixth 4130 tubing item was changed to 2 ea .05" square .065" and the seventh was lined out.
-
I ordered the 24" x 48" sheets from ACS took care of length problem. I have also pop riveted two shorter pieces to get thay long one
-
Hey Les, (or anyone else), I am hours away from ordering my 4130 tubing. Anyone know exactly how much extra 5/8" x .035 I should order? 105 ft + ???. Thanks Rich.
-
My plans say 125 ft. I bought the plans about a month ago.

Purchase some extra while you are at it. If you cut a tube too short you may have just made an addition to the set of wind chimes that always result from one of these projects. ;)
If in doubt about quantities, go old school--get out the plans and a ruler and add up the total material needed.

What Sam said. I bought 140 feet just to be sure.
-
OK. I'll order 130 ft. Wind chime report to follow;). Thanks everyone!
-
30 ' of 1/2" is not enough, ran out on the last brace running from the lower to upper longeron. I need 25" length only have about a foot left. Will have to check the rest of the drawings to see how much more 1/2" is required.
Also the new tank of oxygen, it's empty! Oh well there is always football tomarrow.
-
Glad I bought 140 feet now.
-
I screwed up! Up to late ,No I just screwed up. The last couple of braces are 5/8" not 1/2, glad I caught it while I only had two braces tacked in, I already have them removed. Looks like I'll have plenty of 1/2"
-
Easy to do especially when you are tired. Glad you caught it and have enough 1/2 tube.

Got some of my tubing order from Wicks. It seems nobody has round 7/8" x .062 wall. All that is available is .065 wall so I ordered that. With .062 wall, (1/16"), the 3/4 " vertical fin will theoretically fit inside. So now I have to deal with a .006 difference and a no go fit. How would you subtract the .006 to allow the two tubes to fit together? I am thinking of dividing the difference between the two. The other way would be to take it all from the inside diameter of the .065 wall tube and make it what I needed in the first place. As they say in Jamaica... We be jammin'. Comments please.
-
Maybe you can find someone local with a 3/4 reamer to open the tubing up. I am in the same boat.
-
.058 wall is what's usually used to fit the next size smaller tube inside. the minor slop is ok in all the Eagle stuff where a tube is required in a tube. IMO.
-
I have to agree Joe. The .062 would be kind of a press fit and I would imagine it would be a bear to get apart. Happen to have a piece of 3/4 OD in the mess of welding practice stuff from Wicks. It is a sweet fit in the .058. Not too sloppy really. Well; Jlwright and I will have to get some kind of a 3/4" drill/reamer to open things up a bit.
-
Also; I would think Jim has SOMETHING in that shop of his to do the job,
-
That big reamer is gonna be tough to hang on to in a 1/2 inch drill motor now that it is welded in. I kind of wish I had waited an ordered the .058 wall tubing. On the good side I have the lower longerons bent and welded to the tail piece. I'll be adding cross pieces and diagonals tomorrow.
-
yeah in most apps 058 is the traditional mate to the next size smaller tube.
think yall are talking about the short tailpost that the vert stab fits into? if so even 035 wall will be ok there IMO. its all gonna be cinched down with the brace wires and it aint gonna go anywhere. locked down tight. if you got probs with 063 already welded in its no big deal atall to cut it out. handheld angle grinder with a 1/16 cutoff wheel and you got it out shortly...just be as careful as you can and don't remove any more of the long ends than you can. a dremel with the reinforced cutoff wheel helps in the little tight spots. ive had to cut out stuff constantly on this new thing. it wud definitely be easier *for me* to cut that heavy wall outa there than try to ream it. thats gonna be a bigger problem than the cutout, i hate spinning around on the end of a big handheld drill. you'll have it cutout and replaced before most of us could find a 3/4 reamer to borrow. try not to run the 1/16 cutoff wheel across your fanghur. it's not fun trust me. the bone filings piled up on the exit side will make you go weakneed for a minute.
-
if yall don't wanta cut that tailpost out you could turn down a piece of heavy wall 3/4 AL tube say about 5" long and pop rivet it in the bottom of the vert stab tube. 3" in 2" out turn it to a nice push fit in the stab and the tailpost. the rivets you put in the rib gussets will hold it in. i'd use Avex 4s for that maybe add a few on the backside. it'll still be there when we're all long gone...and a rather elegant solution i reckon

So I'm looking at ordering my aluminum for my tail surfaces. The only thickness on the tubing I can find is in the forward portion of the plans where Leonard calls for .035" tubing. I look at the material list:
4' - 1"x.058"
4 ea 1 1/4x'058x122'
2 ea 3/4x.035x12'
2 ea 5/8x,035x12'
2 ea3/8x.035x12'
1 ea1/2x1/2x .062angle
I know this can't be correct, especially the 122' of 1 1/4. Where would I use 1 1/4" anyway? Help, what are the size tubes being used in the XL and where?
As for as the 7/8 .065 tubing I got from Wicks, a 3/4 4130 fits nicely, I used a 3/4 inch tube inside the 7/8" tail post to hold the fuselage while I tack welded it.

The 1.25" looks like round wing struts.
-
The struts never entered my mind, I was so focused on what thickness the walls were for the other tubing that went right over my head. Has anyone figured if there is a weight penalty for using the streamline struts verse the aluminum tube? And can everything but the control stick be .035"::)
-
So for the X material list is short 5/8" .035 for the cabanes from station one to the top longeron, top diagonal from station 1 to station 2, landing gear, and V struts. It is also shot 3/4" .062 for the axles. .062 x 1/2" sq tubing I will have enough 5/8 for the top diagonal station 1 to station 2 if I splice it.
I think I may try .125" wall 5/8" tubing for my axles to shave a little weight.
