I scratch my head when people want to build ("blue print") 4 generations and upgrades back.....
ok some updates were not upgrades....
but really???
ignore 60 - 70 years ago of learned lessons ???
12. Firewall Brace tubes - the extra tubing effectively makes an X brace on both sides of the fuselage at the firewall. Cubs are known to collapse the engine in a hard landing/crash often crushing the pilots ankles and possibly trapping them in the wreckage.

Or overrun and hit something during an "event" - - Having done that and having had the deformed firewall tubing injure my foot, I'm thinking maybe not a bad idea. On the other hand, with no collapse there something else will collapse or the impact on other body parts be harder.do NOT bother doing that one...
the ONLY way that is an issue is if you FLY your plane into the ground... like whiteout... not hard landing...

Thanks for the info. I have a welded fuselage. It has the inverted dog leg baggage. It lacks the upper and lower x bracing though. From the searching I've done it sounds like maybe my best bet is the Northland Plans. Maybe get a set blown up and printed off for easier viewing in the workshop. Not sure what my first move should be. That would be the biggest help to me from the plans. Providing some type of order to attack the project. I was thinking of getting the fuselage on gear and than start the wings? I'll probably build a all wood wing.
It would be cheaper to build all aluminum wings over wood. Wood spars will cost at least twice as much as metal. Metal spars are easy to source from several different suppliers. I waited 7 months for my spar blanks for my champ rebuild. Douglas fir is more available, about 15% heavier if you don't mind the extra weight. The wag aero drawings utilize a lot of J3 wood spar parts such as aileron hinges, strut fittings etc.
That $1500 seems pretty optimistic. 17 ft long aircraft grade wood spar blanks are the biggest expense. The rest of the cost depends on how much you are willing to fabricate on your own. There is quite a difference in the construction of wood vs metal in cub wings as far as aileron cove, hinges and tank mounting. Of course it can be done, the end result is you would have your own brand of cub wings. Suggest you look at many cub build pictures on this site and wherever else you can find them on the web to see the difference.
Thanks for the advice. I'll continue to check out different builds for more insight. If I remember correctly he said the spars would be around a $1000. Than I can either build my ribs from cap strips, or router out a solid rib. The learning and experience of building the wing myself, ribs and all is very appealing. I have seen some videos of people who formed their own aluminum ribs as well. This would also be a option for me. I just haven't seen anyone make cub ribs themselves out of aluminum? Has anyone here done it?

I bought both Wag plans and Northland plans. I am by no means an expert, but I would suggest using the Wag plans if you choose wood no flaps, or use the Northland plans if you choose aluminum and want flaps. A wise member suggested to me early in my decision making process to use the material I like working with the most. I am a wood butcher, so I chose aluminum. If you really want to see some nice wood wings, look at Roger Peterson's thread or Marty 57's thread.
Neither set of plans are a step by step set of instructions, but there is enough there and plenty of good help here to help you either way.
Hardly anything in the wings is the same between the two plans. Choose between wood or aluminum, buy one set of plans and go for it would be my advice.
Thanks,
Jim
