    Roadable Builds

    I'm currently building an ultralight of my own design that has removal wings but its definitely not "roadable". I choose to not post pics or details because of the flogging I got the last time I mentioned that I was going to be building and designing my own plane.

    Peter Sripol is at it again...

    Please show me where I said I was going to do otherwise? What, do you think I'm going to build something by looking at still screenshots that I scribbled down with my crayons on college rule writing paper and get to welding on plumbing pipe for a fuselage? Or maybe I've been doing over three...

    Peter Sripol is at it again...

    I'm sure I sound defensive, probably because I am, but it's easy to read the undertone here that a few of you likely have it in your head that I'm some lowly gunsmith, incapable of a calculated project and likely just chasing after a dream or the next shiny thing to catch my eye, without even...

    So I guess people should just not try new and innovative things. Or maybe just because you believe something to be difficult for yourself doesn't make it so for others.

    That's not a fair comparison. That's guaranteed unsafe and dangerous. You're automatically assuming that my ultralight is doomed to failure and I've not even built it yet.

    Peter Sripol is at it again...

    The funny thing about me is that I'm a visual person. I make things in my head, view it, spin it around, watch the parts interact and work and then I build it. Ivendone just that quite a few times with firearms that I scratch built for myself. If I put anything down on paper, it won't work. And...

    Building a mini bi plane... very new at this

    A crash at 12 foot is fatal?

    Peter Sripol is at it again...

    I hate to resurrect an old thread, but I'm going to be building something very similar to Peter's Mk4 design this spring, minus the dihedral and add ailerons. I'll be using the foam and aluminum spar wings like his with the addition of plywood ribs between sections, all epoxied together. I have...

    Minimax 1030 build

    Its just a frame made of 2x4's that's a total of 16' long x 4' wide for the plywood top to sit on. I also laid the aluminum angle rail to the one edge to use as a guide. I made absolutely sure it was straight with a solid level (straight edge) as I screwed it down. I was also careful to make...

    Minimax 1030 build

    Well I finally have both sides of the fuselage built. I chose to not epoxy one at a time because I wanted to be able to perfectly duplicate the first one, which I did. I managed all of this in 10.5 hours which I dont think is too bad. Now my question: I'm ready to epoxy these together but I'm...

    Minimax 1030 build

    Correct, but it also shows that the radiata is slightly stronger than the sitka spruce, albeit heavier. I'll do some load testing just for kicks to see.

    Minimax 1030 build

    I used radiata pine because although it is slightly heavier than spruce, it has a higher crushing strength and modulas of rupture. Theres also alot of studies that suggest that the more rings of growth doesn't always equate to being stronger but is more of just a rule of thumb to follow. I can...

    Minimax 1030 build

    I appreciate the input guys. It's amazing how much different the flying community is compared to the firearms community. Had this been a gun forum, y'all would have resorted to name calling and insults over my deviation with the wood already. I truly appreciate the help and advice.

    Minimax 1030 build

    That shows how much I know. I've been reading up and researching everything I could find about aircraft wood and I thought you were supposed to count the dark and light grains (rings). Either way I'm taking the risk.

    Minimax 1030 build

    The piece I'm holding in the pic is 5/8 by 3/4.

    Minimax 1030 build

    Plugged away for 2.25 hours today and got a bit more accomplished. I purposely cut all of the 5/8" dimensions slightly oversized so that I can run it through a planer before gluing it. I figure that 5/8 is .625, not .650 etc... and that weight would add up. Also added a picture of my wood grain...

    Minimax 1030 build

    No but I can snap a pic tomorrow. All the pieces I bought had a minimum of 8 rings per inch from the cut end view, some even more. I thought I did right when I bought the wood. I was very careful to measure the grain slope and made sure there were no knots. Of course the guys on facebook are...

    Minimax 1030 build

    That is the seat area indeed. I'm thinking of just cutting a block to fill in that whole area. And also I'm just building the minimax 1030, not the himax. I posted it on the team facebook page and people are already talking bad about the wood grain. Do you guys see any issues with it being "too...

    Minimax 1030 build

    Some more progress today. Another 2.5 hours of work and I honestly believe I can complete the whole fuselage in about 2 or 3 weeks time just plugging away. My only concerns are that the plans show the support in the one picture going over the scarf joint but mine is in front of it. I'm...
