I have two unrelated questions on building the legal eagle:
1. I have plans for both the legal eagle and double eagle. Wing rib templates for both appear to be identical. Am I missing something or are they the same size and design?
2. I am gathering all the items I need to gas weld the legal eagle frame. I am planning to buy the Smith AW1A torch (versa-torch)
. What would be the best tip(s) to also purchase for welding the chromoly steel?

Wing ribs are the same. The DE wings are longer for greater wing area and have bigger spar caps to handle the increased weight.

Tell your supplier, that you will be welding mostly clusters with .035 wall, and a few things heavier, and a few lighter. He should be able to tell you exactly the three best tip sizes that suits your torch. I run a different brand, and I don't think my numbers would match up with your numbers. But a good supplier should be able to tell you.
Best of success.

In 2004 I bought a smith lightweight torch kit. It was labeled a "Cavalier". Things like that were available from aircraft supplies.
It included an AW1A torch, a cutting torch two single stage regulators which work just fine , hose, fittings flashback suppressors etc.. Two tips came with the kit. Aw203 and Aw205 The 3 is good from 0.032-0.046, The 5 will run you in a range 0. 62 to 0.093.
I have an AW207 that I have welded schedule 10 sprinkler pipe with into a structural piece. 3/16 wall (the 207 is called out for 0.125) a large cantilevered gate on rollers one end. Cool fall weather. Puddle moved slow just watched for
the penetration and snailed along, but has been in service for 5 years and has no issues. I have a 201 and a 202. I use the 203 the most. The 201 is suggested for 0.032 so I have the lower end covered.
You want the 3 and 5 for sure.
Cavalier was $274. 75 shipped. Uh good luck with that part
For you guys who like the meco midget the 3 is like a 1.5 The 5 is between a 3 and a 4 so 3.5.
