I am in the process of ordering my tubing for the fuselage, however there are some discrepancies I am having between the plans and a material list provided in the archives off the sonerai.net The Sonerai II L material lists, states the following additional material are required: 20' 5/8" x .035 Round 4130 10' 3/4" x .035 Round 4130 20' 1/2" x .035 Round 4130 However, the spreadsheet available on the sonerai.net website for the S II L does not include this additional material. I am basing the cut guidelines for the longer lengths off of what has been provided in this spreadsheet. It currently lists *50' 1/2" x .035 cut into (5) 10' sections, however with the additional material this would be (7) 10' sections *150' 5/8" x .035 cut into (15) 10' sections, however with the additional material this would be (17) 10' sections. *50' 3/4" x .035 cut into (5) 10' sections, however with the additional material this would be (6) 10' sections. I just want to make sure my cut lengths are correct with the additional material. If there was somewhere locally I could get this material I would not be as concerned, but since I have to order the material I am being more cautious. Right now I have been going through the plans to verify these lengths and to determine if the cut lengths need to be any different for the additional material. Attachments:

Also in regards to the square tubing.
The plans call out for 25' 3/8" x .035, 6' x .058, 10' 5/8 x .035 square tubing. I can account for some of this in the plans, but not all of it.
Has anyone used round tubing where it is called out instead of square?

BS,
The parts list in the plans is not to be trusted. The list from Sonerai.net I cannot comment on as I never saw it. If you really want accuracy, go through the drawings and tally each piece, then add a little for scrap allowance.
On the question of square versus round, either is OK for the longerons. The only place where square is absolutely required is the carry-thru box.
I feel your pain on those prices!

I was frustrated with the materials list, too, so I am attempting to make an accurate one for all to use. I am not nearly done with my project and will need input from others, but here is what I have bought and used so far on the fuse:
24’ - 3/8”x3/8” .035 4130 SQ tube 8’ - 5/8”x5/8” .035 4130 SQ tube 6’ - 3/4”x3/4” .058 4130 SQ tube 20’ - 5/16” .035 4130 tube (2@ 10’ea) 32’ - 3/8” .035 4130 tube (4@ 8’ ea) 70’ - 1/2” .035 4130 tube (7@ 10’ea) 180’- 5/8” .035 4130 tube (18@ 10’ea) 3’ - 5/8” .058 4130 tube 40’ - 3/4” .035 4130 tube (5@ 8’ea) 4’ - 7/8” .049 4130 tube 1’ - 7/8” .065 4130 tube 6’ - 1” .035 4130 tube 4’ - 1” .058 4130 tube 6’ - 1-1/8” .035 4130 tube If you are building a IIS, you need 10' lengths (4) of the 5/8" tube for longerons or else you will have to splice. Anything over 8' cannot be shipped UPS, so must be freighted. I chose to order in 10' lengths and freight it. (not much more than UPS anyway) Scott

Is there any reason why you only used
40’ - 3/4” .035 4130 tube instead of the 60' called out in the plans?
Thanks
