'40 BL-65 wings on a '41 BC-65??

[t30mg]

Well, were are back to work on our '41 this week. We were just about to start rebuilding the wings when we found a '40 BL-65 close to home. The wings are a lot less work than ours, but our fuse is much nicer as it just got restored last winter.

Will the '40 wings work on the '41???

In 1941 when they went to the 1200 pound gross weight they went to 15 rib wings. even the 41 BL-65 I had that was built in April had the 15 rib wings. The 40 BL depending on when it was built will most likely have 13 rib wings. As long as the 41 is the 1150 gross weight model you should be OK, but if you plan on flying it at a higher gross weight then you need the 15 rib wings IMO.

Don't mean to start a hijack here, but this brings up a question that I have about 13 vs. 15 rib configurations. Are all of the "built up" ribs the same, whether used in an original 13 or 15 rib wing? In other words, if I have one 13 rib wing and one 15 rib wing, both using the built up ribs, can those ribs be used at a rebuild to make two 13 rib wings?

Should be OK.

The built up(truss built) ribs are all the same except the tip rib and maybe the butt rib. There was also a 14 rib wing in there somwhere wasn't there? Either way,to answer the original question on this post....the 15 rib wing will replace the 13 rib as long as you are upgrading. If you currently have a BL with the 13 rib wing and 1150gw then you can use the 15 rib ring as a replacment. To change the wings from 13 to 15 rib it is nothing more then unbolt one and attach the other. They will bolt on & hook up the same way without any or little modification. You can NOT however legally take a 13 rib wing and put on a later model bird with 1200lbs plus gw. The 13 rib wing is only legal on those with 1150gw unless you get a feild apporval unless it might have been an odd ball that came from the factory as a 41 BC1265 with a 1200gw and 13 rib wing(I don't believe there was any). There is really very little or no difference in the early truss built 13 & 15 rib wings other then the rib spacing itself and maybe an extra rib corner brace or two in a couple of places. The spars,fittings,etc are pretty much the same. You can add the extra ribs if you want but make sure you have one as a pattern or a copy of the factory drawings on the pre-war 15 rib wing because there is some minor changes to the layout to make everything fit as it should. Keep in mind that I'm going completely by memory on this so if I have overlooked or forgot something please correct me if someone else knows better. I can go dig out my drawings tell you the exact differences if you need me too. Hope this helps

Mike Jones,

Yes.....I did that 15 to 13 rib conversion last summer. Call me sometime if you want to talk about it.

Thank you Mike. Sounds good!

Well thanks for all the input guys.

I went and looked and the 40 today and it had 1-13 rib and 1-15 rib wing!

I guess we are going to just restore our wings.

Does anyone know were we can get a few ribs, even bad ones that we can get the webbing out of?

I have several stamped ribs in pretty good shape.
Several others in the tribe also have some ribs and may live closer.

Just post which pieces you need when you get to that point and I think you will find all you want as long as you are not looking for built-up ribs.

Someone on the group has been talking to a manufacturer to make the "T" section material to build or repair built up ribs. I will let him identify himself since I don't know how far into the process he is, but encouragement in the form of those looking to buy material couldn't hurt. I know he reads these threads!
The idea was to make the material and sell strips for repair or complete rib kits to build a whole new one. Sounds like a GREAT idea to me.

A few years ago I sat through a Taylorcraft presentation at Oshkosh by a guy making new built up ribs for early J-3's. At that time he was going to also change the dies just enough to make the Taylorcraft ones. However, nothing! The executive director of the Taylorcraft news letter, can't think of his name right now, was there and should know something but I have heard nothing nor have I seen anything from him since, other then his asking for money.

Great, we need at least 10 full ribs, but would prob take 12 if avail.My mech said the stamped would be fine.

What do the ribs usually cost?


Should be good on the nose ribs it looks like.


Also going to need 1 aileron spar if anyone knows were we can find one.

Thanks for the help!

Have not gotten in touch with the person at hygrade metal forming yet as he is out of the office till the 21st of this month will do it then NOW i will need a sample of the T shaped rib material as i don't have any also as a group we need a set of actual FULL SIZE DRAWINGS OF ALL THE DIFFERENT RIB PARTS so when we sell the material to some one they can make a jig to build ribs on now you have owner manufattured parts will sell straight strip of metal and drawings if you need two ribs sell 2 strips and so on maybe the foundation could get involved in this project as I don't have the capital to fund this project Chuck

If I can get some stamped ribs from someone here, I will have some of the T shape rib you can have.
