Bernie, I doubt you'll find one like that, but it's easy enough to make one. First, find a nice wood prop about 34 inch diameter; the chord of the longer prop is likely a tad wider than a 32 prop would be. Cut the tips square, bringing the prop down to the required 32" diameter. Sand the prop to bare wood, removing the factory finish, or at least most of it. Using the picture you posted, take measurements of the leading edge cladding and transfer them to the scale prop, pencilling in the shape of the cladding. Then use some metal tape like heating and a/c ducts are taped with and trace the shape onto it, cut it out and apply to the prop. Burnish it down with a piece of dowel or a Sharpie cap, mask and paint the tips, and then clearcoat the entire prop. If you want to try flying the prop, check the balance at every step, and then when you clearcoat it, achieve final balance with the clear coat.



khodges,

thanks to you, that was a goo tip,
I will try it

Bernie

The crankcase is made from a Mousse can (it has the proper shape), and the cylinder supports on the crankcase are from balsa sheeting. The Cylinders and accessories are from the Top Flite 9 cylinder Pratt and Whitney engine kit in 1/5th scale. The cylinders look more like a Jacobs than a P&W. I will get some pics this evening. I spent last evening roughing it out.

Status: offline 		Hello Waco Brotherhood. How do I sign up. I'm a beginner more or less. My dad was a modeler in his youth and eventually graduated to building a full scale Smith Miniplane in our one car garage back in 1959. Senior had my mom paint the cat Mr. Lucky on the tail and that was his moniker for his flying career. He spent the better part of the next ten years barn storming around the great northwest here in Seattle. I have been involved with flight ever since. I was the oldest son so was dragged to the airport from the time I was about 5 years old. The old man would go flying and leave me to wander around the airport and pester all the other guys in the flying club. You see, back in the 50's you could leave your kid unattended and no one would steal him. Maybe I was just a real pest and no one wanted to steal me. I remember a guy named Chuck L. who was in the hangar next to dad he had a P-51 that I spent most of my time around. I have always been in love with the Waco so have spent the better part of the last 2 months looking for a good kit. The reason why I joined the AMA was to build above all else so I would never buy an ARF. I have begun by collecting as much info and drawings as possible. In my search I ran across the thread for this topic.

Wow, this thread is a gold mine for information on building the Waco. I have already collected a wealth of info and have hardly even broken the surface. I figured that I should probably join in and join the Brotherhood if it's acceptable.

Please get back to me if this is an open membership.

Can you show how you made the flying wires, and how you attach them at fuselage and N struts...
I was planning to use the same cord...Will you fly with them, and how bad do they stretch...

Or call Social Services, but the stealing thing is truly scary, now. How times have changed, when I was 8 years old, I'd hop on my bike and ride all over town, stay gone all day. I wouldn't let my kids do that under any circumstance today.

Maybe it was because I lived in Mayberry, and had Barney Fife and Andy to protect me (I really DID live there, the real name of the town is Mount Airy, where Andy Griffith is from)

Welcome to Wacomania, Mr. Lucky. I wish my folks had abandoned me at an airport when I was a kid, sometimes.

Status: offline 		Yeah, way back in the dark ages (when I was 8 years old) I had a 14' Memphis Belle fishing boat with a 12 horse Buccaneer outboard. We would practically live on the Cumberland river during the warmer months, and our parents did not worry about our safety. We were taught to be self-reliant, and we lived up to the instruction. When I was 11, I would ride my Harley Hummer to Nashville (10 miles away) and get what I needed at Fats McCullouch, Harley-Davidson, and come back home. No one bothered us (Police included) and we were allowed to grow up in a healthy manner, I.E. without being afraid of the Boogey Man (we actually called him the Booger Man). Now the teachers and the Police departments hands are tied by the Department of Children's Service, and the Kids are in charge. God help us.

Okay,
Here are some pictures of the initial stages of the dummy engine. I think that you will agree that the Mousse can gives the correct shape and size for the crankcase. As I said, the cylinders are from the P&W 9 cylinder engine from Top Flite. It is supposed to be 1/5th scale, and it fits well inside the cowl. I need to color sand the assembly, and paint and detail it. I have the pushrods, the ignition wire conduit, and the rocker oil lines figured out, as well as the ignition wiring, and the spark plugs. I need to come up with a data plate, and it will be ready for mounting. Let me know what you think.

The silver wire did not photograph real well so I included a shot of the cording I use on my Super Stearman (ARF).
The hooks are what you will find in a fabric shop, get the large ones.
To make the "wires" I made a small loop secured with thread. I place a drop of CA, then when the CA was dry wrapped down 1/2 inch (or so) to look like the rigging. I made small holes for the hooks and after re-shaping them so the cord is easy to slip in and out, I CA'd them to the fuselage and wings in the (approxamate) scale location. I fly my Stearman with the cording I made for it and it works out real well, adds a lot to the looks of the plane in the air. They do not appear to stretch too much, I have been using these on the Stearman for a couple of years.

I just got off the phone with Brad (Stan's Fibertech) about the cowl. He says that he will have the Cowls ready in a few weeks. They will be priced at $57.95. That seems a little steep to me, since he didn't have to develop the plug to make the mold from, but it's his business, so he can charge whatever he wants. I wish that we had researched this a little more before we did this for him. But at least we will have a scale cowl available to us. He indicated that his e-mail was having a problem, and I am to call him again tomorrow (Thursday 10/25/07) night. I'm going to order one or three.

I ordered 3 cowls and 3 sets of wheel pants last week. Good to know things are progressing well. Price is a little high, but considering that this is a special order to our specs., I think that's OK. To get the exact cowl for my model - I'm ecstatic! I also sent a photo of the aircraft I'm modeling and he said his pants are the same - unlike Fiberglass Specialties, which are close. Looking forward to getting them!!

Status: offline 		I think that he could have cut us a little slack, since making the plug is the most time intensive part of production. All he has to do is to make the mold from the plug, and start laying the parts up and pulling them. He can make one every day with only one mold. Seems a tad tall to me too, but they are specific to the Jacobs radial. They will work for other models that use this engine in the same scale too, so he does stand to make a tidy little profit.

I enjoyed 3 more flights on my Waco yesterday, best landings ever and the 170 Saito is running flawless!

Jim That set up looks very nice and practical. I'm not quite sure about some of your explanation. Is this rough drawing approximately what you mean for making the hooks??

For anyone keeping track of various items in this thread, you will have to reference them by post #, and not the page #. We went through this a few months ago when RCU changed the post count to 20 per page and now we are back to 25/page.#@!!!!

Question. Regarding the ailerons, Were they covered with fabric or aluminum? There is a picture some where here showing rivets at the edges.

The connecting rod moving the upper aileron from the lower aileron, what were they made of? wood ?

The ailerons are all aluminum, 34 ribs and 35 flats riveted together. The connecting rod is a metal tube (round or streamlined) with adjustable bolt on ball links on each end.

P1 Lower end of connecting rod (round tube), upper end the same
P2 Top view of aileron
P3 Front view of aileron, note slight curve on top,near the tip, more curve on bottom. Curve on bottom starts half way between the last 2 W-6 ribs, making the last W-6 shallower at the trailing edge. This does form wash out at the tip. Top curve starts between the last W-6 and W-7. Full size W-7 was about a 1/4" lower than W-6 and W-8 was about 5/8" lower along the high point of the ribs (top spar area).
P4 Tip showing wash out
P5 Upper end of connectig rod, note the top end is closer to the trailing edge than the lower end.
P6 End view of connecting rod (streamlined tube) showing rod lower mount through bolted. Upper mount is reversed.

I also learned not to hit send twice fast.

I apreciate the pictures and your description, I was thinking that maybe back in the 1930"s when the airplane was designed they were covering control surfaces with fabric, so no use for rivets.

Thank you.

Yes, I just opened the eye of the hook and cut the other end off. I use a small drop of medium CA to hold the hook in the wood. I fabicated the hooks on the Stearman out of "T" pins, but the dress hooks work as well if not better and are easier to make up.
If you still have questions, drop me a PM.
