    Awesome Mike! You are an inspiration to others. Reading your progress makes me want to build. We are getting ready to start the mold on the SnoShoo wing. Are you going to Reno this year?

    I really want to to but it will be hard because two weeks prior I'll be in Florida for 12 days.

    Projects are difficult for me because I carry a lot of responsibility for a lot of people just like most of you so I'm sure everyone understands this. My day starts at 4:30 and doesn't end until 5:00 or 7:00 depending. I'm in CrossFit and my wife trains for Ironman. By the time we mix that all in with 3 kids and a business there's so little left in the day. Again, I think most people here understand what life throws at us.

    But there's time, I'll make time because I truly enjoy fabricating. I may just shut down a part of my business and reduce my impact. There's a certain point in which extra money just doesn't make you happy, it never has for me. It's just more work. I've never gotten excited about "things" I more in love with the experience, people, events, creativity etc. So I think I'm gonna just reduce my business a little and focus on a few more things that are fulfilling to me.

    Airplane building is fulfilling for me and I miss it.

    Laying tube later today. It's an interesting fuselage. Here are two photos. If you zoom in you'll see I put a straight edge on the longeron and you'll see a built in crown. When the sides are brought in I'm curious if the math is correct and she'll be flat. I'm ok with it regardless but I am curious if the math is right.

    Then there's the turtle deck "hump". I'm not sure what the purpose is but I'm gonna smooth it out. In this photo you can see how the center is a piece of 1/2" and he's got 3/8" stuffed in the front and another 3/8" stuffed behind it. I'm confused because why the large diameter in the middle of the turtle deck.

    IMG_20190803_082532852.jpg

    So that's just a couple interesting things of many on this fuselage that's kickin around in my brain while I lay some tubing.

    Think minimal. Minimum materials. Minimum effort. Minimum cost. One 1/2” piece is heavier. One pretty curved piece is harder to make. Probably when made, it was cheaper. His genius is building farm implements that were fast. If he deemed it needed a curve, it had a curve. If it could be straight, he built straight. As beautiful as this thing is, it’s a tool. A tool to bring home prize money.

    Plenty of leeway to do things different. I probably would. Making it better than he did?Probably not.

    Cut all 12 pieces that make up the 4 spliced longerons.

    IMG_20190804_105134354.jpg

    Set up my drill press to drill the rosette holes. Jig is from Harbor Freight. Cheap and it always works because it's just a simple one piece extrusion.

    IMG_20190804_103845852.jpg

    I'm out of practice so I cut two pieces of 3/4" and drilled two pair of perpendicular holes on each end. That gives me 4 full practice rounds.

    IMG_20190804_105216074.jpg

    While I've known how to weld for over 30 years and at one point did it for a living I'm very much out of practice which make me weak in this area. Some of you may remember my practice jig which I've had and used for many many years. Welding is a art, art requires practice so that's what I'm focused on this week.

    Here's a link to a thread for further reading on my practice jig.

    I'm really rusty, been too long but sure feels good trying to find my groove again.

    Wittman splice, 4 rosettes. 1st practice piece.......not good. I'll get her though.

    Like you said welding is an art. I welded for a living for many years welding Boiler tube for coal fired power plants, but now at my age I couldn't pass a welding test. My hands are shaky and even after getting new lens in my eyes, I don't have the perfect vision that I used to have to see all the minute details of the puddle when welding. Welding is all about puddle control and when you can't see, you can't control.
    Its really frustrating now when I look at my welding. I did all the welding on the JMR and that was right at the end of being able to see. If I build another homebuilt , it should be aluminum or wood.
    My good friend of 45 years, Dallas is two years younger than I am and he still can see good and his hand are still steady. He is an artist at welding and he is the best I have ever seen. So if I build another airplane, he will have to do the welding for me.

    At your young age, all you need is a little practice and you will be back in the groove.
    Have fun.

    My wife did a 70.3 tri yesterday so she passed out mid day today and the boys want to play video games so I was solo. Decided to head to the shop and kick out those longeron splices.

    I began by striking a chalk line on the edge of the table about 2"in. Split the difference with a dial caliper and set the blocks. It's 3 pieces, 3/4", 5/8" and 1/2". I decided to calculate everything out and make one big long straight longeron and bend them later on.

    IMG_20190811_192955650.jpg

    I pre drilled holes for the rosette welds 90° apart and once everything was shimmed up to the centerline with sheet metal I plugged the tops. Indexed 90° and plugged the tops again, index again etc until all 8 were done.

    IMG_20190811_193004439.jpg

    Once cooled I set up to weld the circumference of the butt itself indexing as I went along.

    IMG_20190811_194304748.jpg

    Cleaned up while is was cooling took it outside to examine how straight it was. Turned out perfect, no warpage so that's good. Gonna pound out those other 3 and that's enough for this session.

    Any progress? If you need pics I can reach in and take some. Currently I'm making the tank. Have one in fiberglass but don't like it.

    Very nice. I do make progress. I left for vacation Saturday morning and Friday before we left I worked on tacking together fuselage sides. Found my first mistake in the plans layout otherwise the plans are spot on.

    Nice. Just keep us informed. My wife is training for her 6th Ironman so I get it.

    Had some shop time. The boys wanted to paint instead of airplane stuff so I cut them loose on the back of the shop and just let them figure it out. As a father it was cool listening in on the conversation between brothers. I'm so lucky to be a dad.

    I managed to fit some more tubing on the V-Witt. Almost got both sides done.

    Mentally, it's not easy putting 3/8" x .028" tubing in a fuselage. I mean, it just doesn't feel natural.

    There's about a 3# difference in the entire airplane between .035 and .028. Steve really built this thing minimal.

    Wrapping up side two shortly. Looking forward to putting these together and seeing how close Steve was with that built in arc on those upper longerons.

    Good-looking tube fits, Mike.
