Welcome, Tim. It will be interesting to hear & see what you intend to implement in your build of a Scout. Just low cost simplicity, as intended. The basic plan is to not get fancy and to keep it light. I know the Air Camper has evolved a bit over the last near-century(!) so the first job is to ...

Chuck in Indiana

Wow! That's a bargain. Making them per the plans is really labor intensive.

Chuck in Indiana

No steel in sight, decided to do something else. I made these fittings for Bill..20 years ago.

Chuck in Indiana

Ed (RIP) and I originally just left it open on "Footloose," an S1S Pitts.

It was definitely wonky before changing it, but I doubt the Piet will have the same rate of climb and pressure changes in the cockpit.

Chuck in Indiana

Thanks, Oscar.. the steel has been sitting at the Indy USPS distribution center for almost a week now.

Apparently, that is where postal stuff goes to die. (grumbling and shuffling off)

Chuck in Indiana

More time passes, and I've finished the wings, stored them in racks in the hanger, and brought in the fuselage to finish it. (Hopefully) https://static.imgzeit.com/reduced/2bc66f0155eea548/20250222_105845.jpg https://static.imgzeit.com/reduced/4e9d0543b48b9c59/20250222_105857.jpg Ordered a tail spri...

I wonder if you could heat the staple with a soldering iron to soften the epoxy locally?

Chuck in Indiana

Thanks for taking the time to document this. It will be a good resource when I get there.

Chuck in Indiana

Thanks for the pix! I know sometimes you don't think anyone cares when you don't get any response. This stuff is valuable info.

Chuck in Indiana

Time passes and this wing is coming along nicely. I laminated the 1/4X1 pieces, made a steam box and formed them for the tips.

Chuck in Indiana

The reason I'm asking is there is a guy that has 17 for sale. I'm not sure he knows what they are, but he says as closely as he can tell they are 36TPI. I'm thinking that would be a #8 thread, and *maybe* a Piet would require #10? Buying new ones runs pretty heavily into my play money.. :D I haven't...

Chuck in Indiana

What is the minimum size?

Chuck in Indiana

Thanks again..

Chuck in Indiana

Inquiring minds want to know.. did you just run the plane down the steel jig?

Chuck in Indiana

Alrighty, now! Thanks for that..

Chuck in Indiana

What did you use to get rid of the biggest part of the scarf?

Chuck in Indiana

One piece at a time.. attaboy!

Chuck in Indiana

Me, too. It's quite a resource, and it keeps me from trying to reinvent the wheel sometimes.

Chuck in Indiana

Good as new..

Chuck in Indiana

The turtledeck is done.. I guess I'll use the 14 X 1 for the tip bows. Thanks!

Chuck in Indiana

Looking at the stock I have from when Bill bought everything..I have two 1X1X 8 ft. and two packages of four 1/4 X 1 X 8 feet. Maybe the two packages were meant for the tip bows and the 1 X1s were for the fuselage somewhere? Is there somewhere in the fuselage that uses 1/4 X 1 spruce that I don't se...

Chuck in Indiana

(cross posted from the Pietenpol facebook page..) Uh oh. I've always said that scratch building an airplane is simply solving one problem after another until there are no more to solve. 😏 20 years ago (!) when Bill was building this Piet, I made the steel parts for him as he brought me drawings. The...

Chuck in Indiana

Nice work, Richard. I'm a machinist, not a woodworker, but have been learning about hand planes on this Piet project. It's strangely satisfying watching a chip roll of them.

Chuck in Indiana

I have routed 1 inch spars also. The routing didn't take long, and I got to buy a new tool. :D Who doesn't like new tools? I have a couple of planes, now.. router bits.. a really nice chisel set from England..a tool to sharpen them, and have made several table saw tools. And yes, the weight savings ...

Chuck in Indiana

Yeah, a block plane is great for this and things like trimming overhanging plywood, etc. Carefully going at it with a chisel works too.

Chuck in Indiana

Nice work.

Chuck in Indiana

Yeah, the center section is pretty easy because the rib is more inboard than on the wings and you just have to clear the fittings. I've done essentially the same on the CS.

Chuck in Indiana

Saw it on facebook.. it'll get you another Attaboy here.

Chuck in Indiana

Thanks for the answer, Ken. That seals the deal for me. I'll do the same way as I did the center section.. varnish the fitting area, install the fittings for the last time, and do whatever it takes to get the rib on. Beef it up as necessary, or "Hammer to fit in field, paint to match."

Chuck in Indiana

Here's where that lower fitting and bolt interfere that I was talking about a while back.

I wish the west coast site was up so I could look at what others did. Move the hole, or just cut up the rib?
Finished adding 2.4 lbs. of lightness to each spar today..

Chuck in Indiana

Adding some lightness..

Chuck in Indiana

I'd pony up some cash, too..

Chuck in Indiana

Chuck in Indiana

Whew..

Chuck in Indiana

Attaboy..

Chuck in Indiana

What is that crack all about?

Chuck in Indiana

Waiting for the T88 to set up

Turned over the flop and added the 1/16" ply.

Time to start on the wings, I think..

Removed a lot of the plywood from the truss today. I also removed the rest of the controls that would be in my way.

Does that work with T88?

Chuck in Indiana

Whew! Thanks, Pat.

Uh oh. I was getting some really good info there. Anyone know what is going on?

Chuck in Indiana

How do you plan to get the plywood off? That looks like a tough job to me..

Chuck in Indiana

Sometimes, worrying over a problem is worse than actually doing it.

Nothin to it..

Chuck in Indiana

Thanks, Ken. My little Japanese pull saw made quick work of separating the flop from the center section. I've since glued on the spar caps. Still need to install 1/16" gussets on the ends of the false spar and flop spar. Then..I think I'm ready for the big job.. fitting up and gluing the 1/8 bi...

Chuck in Indiana

Compression struts and flop spar glued up..

Chuck in Indiana

It's a Legal Eagle. I was just showing the concept of the building table. The spars are very light, though.. and the wing has been tested to 4Gs.

Chuck in Indiana

If you sheet the bottom, it makes a very stable box. Also, if you move the I beams inboard a bit, you can store long things on the outside where they are handy.
Ferinstance..

Chuck in Indiana

My guess is bad manufacturing process, and all from that batch will do that. I'd try to get my money back and order from somewhere else. (shrug) What a PITA.. I ordered green epoxy primer from ASS, and it was white. Mislabelled. Told them about it and they sent me more white that was labelled green....

Chuck in Indiana

Is that an old library card catalog against the wall? That it is. :D It holds end mills from 1/32 to 4 inch dia. Drills, reamers, counter bores, taps, dies, tap & die wrenches, etc. 60 years (gasp) of machine shop stuff. I'm turning the machine shop into a wood shop as we speak. :D They don't c...

Chuck in Indiana

Couldn't put it off any longer and started gluing..

Chuck in Indiana

Not at a high load area like cabane/strut/LG attach. I would think aft of the cockpit would be good, but a properly done scarf joint is substantial.
