If it is going in your Bearhawk, why do you need paperwork?

Dave you can add to the lower belt by using 1/8 cable between the floor and the belt fitting. Great seatbelt, I have installed them in everything I have owned, Pa11, Champ, J4 and my Ex Cub. You can use a different brand inertia reel by changing the fittings on the belts to the ones that fit the rotary.

Interior panels are ready for cover and powder coat. Dakota Cub fuel valve and trim crank, under seat storage box. Airframes HD extended gear, new shock cords by Univair installed. Wheel and brakes blasted, rebuilt and painted up. Tailwheel rebuilt with Airframes rebuild kit. Fuel lines run for R/L/Both Dakota set up. Working on control cables. Waiting for an engine mount then I can fab up the forward sheet metal.

Anyone know if Mark at Thrustline is still around? Can't get in touch.

Looking really good Dave! I just read the whole thread from the beginning and learned a ton. I spoke to Mark about 3 weeks ago, so he is still around. May be out moose or caribou hunting. He usually responds pretty quick when he returns.

That center stringer looks really high. Was that done on purpose?

Also, looks like the rear fuel line off of the left tank goes aft behind the D window instead of down in front of the D window. Is that how it is routed or just hard to see in the picture?

Also, it looks like there may be low points in the fuel line that could accumulate water?? In my opinion the lines should run downhill to the gascolator at all locations, in three point attitude.

Mark made contact with me so all is good.
Steve, not sure about the stringer height, maybe the photo angle is making it look different but it seems about the same as others I've looked at.
The fuel lines in the picture do run behind the rear window, I'm using Dakota Cubs headerless fuel system and it seemed to allow for this as a way to get the lines to run downhill all the way but really they don't, at least with the 3 inch extended gear and 26 inch Goodyears there's no way to make it downhill all the way in a 3 point stance. It's something I've been planning to redo so any suggestions are appreciated.

T in a quick drain at the low point. Lots of planes have them.

Here is the center stringer mount on a 1982 Super Cub I am rebuilding and it is consistent with the drawings and everything else I have worked with. The center stringer just appears to be very high in your pictures.

I am using the Dakota Cub headerless fuel system as well and it pretty much follows the stock system from the data I have and drawing DC11469. Here is how I have always done them which is like Piper routed the lines less the header tanks.

Here is drawing DC11469. Diagram 1 and 2 give a clearer picture and show a constant down flow.

Thanks Steve, that's a big help

I have standard gear and 26" Bushwheels, and made it run downhill all the way. So that's very close to the same fuselage angle on the ground. It was close, but made it.

I remember you had some strange modifications when you got your project and figured someone has taken some liberties with your airplane over it's lifetime. Do you have the Northland drawing CD? If you need any pictures of anything I have thousands of pictures I have taken over the years from the rebuilds from at least 5 original Super Cubs. They come in very handy when trying to remember or figure out how something is suppose to be.

I've looked at many of your pictures and they've been a big help. My buddy Bill has let me use his later model SC as a reference too and the frame mods and repairs etc are being done by IA's with alot more Super Cub experience than me. I've been using the parts book and Christian's website as a good reference too but yes there are many smaller things that are hard to make out from the drawings. I've got a great IA to keep me in line and I have to constantly remind myself to not let my 'experimental' mind get in the way so once in a while I have to redo something.
I don't have the Northland CD, is it more detailed than Christain's site? Do you have your pictures archived here somewhere?
Thanks again.

I find the Northland CD handy as well as Christian's site, the drawings from the Short Wing Piper Club and the parts manual. Here are links to two photo albums I have uploaded.

Some good progress with the Thrustline mod and cowl fab
Just for reference here is the standard set up before the mod
You can see the angle difference. Spent some time getting the nose bowl / ring gear / spinner plate clearance right, squaring it all up nicely and lowering the bowl as much as reasonable.
Now for the doors.

I've been following Pierce's lead. Lots of work in the forward sheet metal, getting things positioned right. I had a banged up lower cowl and a borrowed set of doors and top cowl to pattern from. I started with the top cowl, rebuilt the bottom with Mike's mod and cut the doors oversized then snuck up on the final size. Steel parts blasted and primed, rebuilt the latches. Came out real nice. Beefed up the weak areas, fit the sutton exhaust which is a real nice piece.Attachments
