Title: Rib/gusset/doubler clarification
Post by: Tailwinder on August 22, 2026, 05:13:59 PM
New LEXL builder and making ribs.  Most are done, but 7, 12 and 13 yet to do.  Using the Iron Design plans supplement.  Looked through earlier posts but still unclear on a few things.  Have the A1 doublers as shown on the Iron Design been eliminated/changed, or where do they go?  What I have come up with is rib #7 has a 1/4" on root side and .8 mm on tip side.  Rib #12 has 1/16" on root side and .8 mm on tip side.  Not sure what is on rib #13.  Can someone confirm and/or fill in what I'm missing.  Thanks.

I am also using the I.D. drawings. A1 does not go anywhere. Cut it up and use the ply for something else. Your rib #7 & #12 sound good. #13 usually has 1/16" on root side and some people put 0.8mm on the tip, some don't use any doubler on the tip side. I cut slots for the aileron hinge blocks in the doublers for #12 & #13.

AS most of you know, I have been vacant for sometime, deep into another CAD project. But looks like this got resolved and also looks like excellent work. 

Unfortunately sometimes when I strive for clarification, it inevitably creates some confusion in other areas. This certainly might be the case,  not an excuse. Sorry.
