How old is your nephew? This is a really cool project, lots of math and stuff...

spidermonkey 05-04-2021 08:46 AM

Riflepistol, yes chromoly frame with aluminum skin. Wings will be aluminum frame with aluminum skin. He hasn’t ordered his wing kit yet. That’s still a ways down the road. And my nephew is in his early 30’s. Typical guy, I am, I don’t know his exact age. :rolleyes: Good Huntin, and God Bless, Rusty

Forgot to put this one in the other day. After I left that day he did get the running gear installed. Now at least he can pivot the plane around to different spots. :D I helped him set it on a sawhorse that he put right at the firewall/where the motor frame bolted. I grabbed the frame and just picked it straight up while he slid the sawhorse under it. Granted, it was balanced on a pivot point, but still amazing how easy it was to pick the whole front of the plane up by myself high enough to get it under there.

RifleBowPistol 05-04-2021 09:06 AM

That would be cool to build and own a bush plane, style plane. I would be moving to Alaska for sure, if I got it built.



So what size tubing is the frame built out of, diameter and wall thickness? Then what thickness is the skin?

Buck_jane 05-04-2021 09:33 AM

This is awesome. Can't wait to see the final results.

spidermonkey 05-04-2021 10:19 AM

Riflepistol, all I can vouch for for certain, is the motor frame I welded up. The majority of the tubing was 1.25 OD, .049 wall thickness. Motor mount plates were 1/8” (.125), and the smaller OD (3/4”) tube where it’s bolted thru the firewall is also the heavier wall .125 like the motor mount plates. But, the biggest portion of what was welded together was .049 wall thickness. Didn’t even pay attention to the thickness of the aluminum he already had riveted on, but it’s thin, definitely thinner than .049. And didn’t ask bout the fuselage frame he bought pre-made.

spidermonkey 05-04-2021 10:50 AM

I was thinking the aluminum skin was around 22 ga. (.025) just going on what the thickness felt like when I handled a couple of pieces he had laying around. Just had him tell me it’s .020 (24 ga.) 6061 T6. So my redneck hand measuring method wasn’t too far out in left field. It helps having to use my decimal/fractions daily on my full time job for the last 30 yrs. Most times I can get close. But when ya start getting into the super thin gauge stuff, I don’t have to deal with it quite as much. Also, it messes me up sometimes cuz the same gauge # steel will be thicker than aluminum. Always gotta be something to confuse us I guess!

Man 05-04-2021 05:43 PM

Very Cool! What this going to set him back when all is said and done?

spidermonkey 05-04-2021 07:12 PM

Man, don’t know for sure, but I know he’s saving hisself thousands by doing it the way he is. Meaning, using a “non-traditional” engine instead the Rotax that most everyone else uses, getting his “brand new/old stock” turbo for $600, instead of the $2000 Yamaha was wanting, and the list goes on. Yeah, his brand new Yamaha crate engine didn’t have the turbo in the package, even though it’s designed for it. :rolleyes: He’s also getting a discount from Dynon on his avionics instruments. Dynon is evidently a main/big supplier for the experimental/light sport airplane segment. They are partially sponsoring him as long as he puts some of their stickers/logos on the plane. Said he was saving bout 6K on that since they are “sponsoring” him, even if it is partially. Hate to know what it was full price! :eek: I guess building a “one off” that hasn’t been done yet has a few perks. I’ll fill y’all in as best I can. But, I know since he’s doing this slowly, meticulously, and as he has funds available, it’ll be awhile till completion. Says he’s shooting for next spring. For one, he said that Dynon wants to use it at some air shows next spring. Soooo, guess that means my dirt-dobber welds will be on full display for all to see! Also, evidently there’s a big gathering air show at Oshkosh Wisconsin every year. Good Huntin, and God Bless, Rusty

RifleBowPistol 05-04-2021 09:51 PM

Dang, Oshkosh is the BIG DEAL in aviation every year.

If they turn this into a kit, that would be pretty cool deal. I like the power to weight ratio and the fact is has a boosted engine. Would make for one hell of a bush plane, or just very fun plane, to do stupid stuff in.

spidermonkey 05-04-2021 10:07 PM

Yeah, he’s got quite abit more (going by what he says) power than the usual engine installed in these planes. The Rotax for this plane I believe puts out 80-90 hp? Whereas the EFI Yamaha with turbo will put out 160-180 hp. Plus he’s right at 100 lbs less in weight, engine wise. He could do stuff to get it more “hot” he said, but wants a do all, user friendly, fuel efficient plane, but still have plenty of power. Will be an interesting build for sure!

spidermonkey 05-05-2021 02:06 PM

Chase, he didn’t know anymore than you on them raising the gross wt on light sport. Just “heard” that there is a proposal out there about it.

LivinADream 05-05-2021 06:22 PM

Sweet deal, oshkosh is huge. They have a fly-in in east tx as well, not near as big as oshkosh but a pretty cool looking venue. (I've not been). Reklaw I believe it's called.

spidermonkey 05-05-2021 09:24 PM

Who knows, he may plan on the Reklaw gathering as well. Like I said, he’s shootin for next spring to keep everything paid in full, but wouldn’t surprise me if he hit all the shows he could. If for no other reason, than just an excuse to fly the new toy! He lives in the panhandle, in Vega, so finding a flat spot he can take off and land won’t be too hard! :rolleyes: But he’s also in with some buddies at the local municipal airport and they all went in on a hangar. Good Huntin, and God Bless, Rusty

captainsling 05-06-2021 06:25 AM

I remember going to Oshkosh by gosh a few times as a kid. My grandpa and I would fly his Cessna up there. He would do all the cooking for everyone. It was a big deal. If you get a chance....go!

Yes, a friend of mine has a plane and he was telling me that annual can be super pricey!

Awesome thread, OP.

When you go from tig welding an intricate hyper thin-walled airplane frame one weekend to stick welding a 6-5/8” x 1/4” wall pipe overhead the following weekend. Kind of opposite ends of the spectrum! Ok... I admit... really just put this up to kinda keep the thread alive and kicking. :D Good Huntin, and God Bless, Rusty

RascalArms 05-12-2021 02:02 PM

Another fine welding job on the pipe entrance Rusty. I’m laying odds that thing will be there and standing long after we are all gone on! 👍👍

spidermonkey 05-12-2021 08:30 PM

Thanks Joel! And if it’ll dry out enough before the next batch of rain, next week they’re saying, I’m hoping to set posts end of week/Saturday. Just building two “wings” coming off of the big overhead to the fenceline on the road. It’ll have 4-1/2” posts, four 1-7/8” pipe horizontal runners, and posts will be dome capped. After that, I’ll tie in that old pipe fence to my overhead, and then comes the gate(s) of course. Good Huntin, and God Bless, Rusty

Dale Moser 05-12-2021 11:19 PM

That is cool as all get out! A home made airplane is cool enough, but that TIG fab work is unreal. I hope to learn that one day, a little bit, but not on an airplane! Me and some buddies have joked in the shop before "hell we don't have to fly this thing!", and I aint ever gettin in any airplane that I welded on!


But I'd get in that one! That looks like a hot rod!

Please keep us posted as it moves along. That's really a neat project!

spidermonkey 05-13-2021 07:34 AM

Thanks Dale, and will do on the update. Right now I get any updates/info as he texts em to me. Good Huntin, and God Bless, Rusty

Chief Big Toe 05-20-2021 11:51 AM

let me bump this, and see if Rusty has any updates....

spidermonkey 05-20-2021 08:43 PM

I wish I did Chief! All’s been quiet on the western front... Actually did text the nephew yesterday, and he said he’s been busy and ain’t had a chance to “play in the shop”. :( He’s thinking next week is looking better though. I wish I had some cool pics to share, but nada. I’ll post any as soon as I get em! Good Huntin, and God Bless, Rusty

If you can ever get him to Olney, TX....give me a shout. I can hook him up with a tour of where I work. It’s called Airtractor Inc, & we build modern day crop dusters, amphibious Firebombers, & a miltary plane. We make the majority of everything in-house.

wow what a build

spidermonkey 06-05-2021 10:20 PM

Awesome Beardedbuck! And you’re right! He’d be in hog heaven! Who wouldn’t?!! Our family on my dads side seems to have a lot of pilots in the gene pool so to speak. My dad had his pilots license, dads older brother flew in the USAF in Korea, his younger brother was KIA in WWII flying a P-38 Lightning. So my nephew has had a grandad, and a couple of great uncles that flew, so I guess he comes by it honest. Thanks for the offer! I’ll let him know! Good Huntin, and God Bless, Rusty

Lungbustr 06-05-2021 10:46 PM

You know those were originally oxy acetylene welded right. Your tig welds are way more than enough.

Beardedbuck. Those air tractor conversions are awesome!! Saw an article about them being used in africa.

spidermonkey 06-05-2021 11:01 PM

Lungbustr, yep, I knew that they were originally oxy-acetylene welded. Along with race car frames as well. Tig welding is “new” so to speak. Funny thing is, I do lots of oxy-acetylene welding too, cuz I like doing it, it makes a good weld, and just to keep my old school ways honed abit. If I’m welding say 16 ga sheet metal, oxy-acetylene makes a cleaner weld cuz it’ll “burn out” the black scale that’s on the sheets. Where if I Tig it without sanding the weld edge, it’ll usually pinhole in a couple of spots from the impurities of the mill-scale. Actually I think I posted some oxy-acetylene welding on a feeder build thread I did, can’t remember for sure? Anyway, thanks for the feed back, and vote of confidence! I never concern myself with my welds as a rule, BUT… it works on your nerves abit considering this application! :o Good Huntin, and God Bless, Rusty

Yes, our plane are all over the world. We've had some come back from areas where they grow the coca plant that have bullet holes/dents in the bottoms of the planes. The pilots are hired to spray/kill the planted fields and there are guys on the ground hired to try and shoot down the planes. Those planes have a Kevlar re-enforced belly and bullet proof glass in the cockpit.

I love seeing young folks with the drive and desire to build aircraft. It shows a lot of dedication and discipline to do so. Things like this have to have a lot of thought process involved and loads of attention to detail. I mean after all, you're putting your life on the line once you load up, take off, and leave the ground......so things had better be right!

I hope Spidermonkey will keep this thread updated on a regular basis, as it has really perked my intrest! ;)b

spidermonkey 06-06-2021 12:31 PM

I’ll do the best I can, only info I get I get via text when he gets something new done. Which here lately he hasn’t got as much done. Been busy I guess. Good Huntin, and God Bless, Rusty

spidermonkey 06-06-2021 10:50 PM

Here is a link to his YouTube channel he keeps going bout the plane build. Hope it works, cuz me and technology don’t usually get along too well. :rolleyes: Plus, he he has other videos too, gun builds, cerakoting, and I don’t know what all else. I can barely figure out how to watch a video, much less put a video on YouTube. Oh well, leave it to the youngsters! Good Huntin, and God Bless, Rusty

That looks like fun stuff there. My type of crop dusting. That gun in the bottom picture, looks like the same one the used to use on the Cobra helicopters years ago. That could be pretty cool, you could get up close and personal with that thing.

My uncles car got in the way one time of a crash landing on our farm.

The prop strikes cut through the roof each rotation of the prop. It was pretty cool, im sure not for him though.

Pilot was fine, seems they are made to crash land.

Before rice farming slowed down so much this area was pretty good for making money crop dusting.

Paycheck 06-07-2021 08:54 AM

This is very cool!!! If only I could turn back the pages 20 years, I think I would do something like this. I always wanted to fly. But then I would not be on a bow hunting forum. ;)
