Spring has sprung, yet I still have a building project I want to do.
So, given that I'm an experienced stick, sheet and tissue builder, what's the quickest way to build a decent (i.e. not solid balsa) wing?
The resulting lifting surface will be stuck onto a fusalage-like bit of balsa plank, with appropriate tail feathers and 25-sized engine.
Learn to cut foam? Build a constant-chord plank, with tapered flaps? Something else? Jig-built? "Cut em off later" feet on the ribs? Something else?
Going and buying an ARF would be _the_ quickest, but that's cheating.

If you can get laser cut ribs with tabs, you can hack out a wing on a flat surface in an evening.

I'll take that to mean if I can stack-cut ribs with tabs in an evening, then I can have a wing in two (I'm working through a couple of Bags-o-Balsa; I refuse to spend money until I absolutely must).

Remember that Brodak sells wing rib kits for all of their planes. Find a wing about the size you want, and order the ribs. Price is about $30, and worth every penny of it! I've built the last 3 planes (of my own design) using Brodak ribs!

Or build an I-beamer with sliced ribs.

Just buy an ARC. LL~ LL~ LL~ Really getting a laser cut kit with tabs on the ribs and a super flat surface is the quickest for me. For almost gauranteed straight wings a wing jig from a good supplier is for me the best. I have the CLC Jig set from Jim Snelson. I have also had my own rod jig and the Tom Morris Lincoln Log jig set. To do it right you don't want to rush it. H^^

If you decide to try foam let me know... to see part of the video that my son sells for me on the web go to youtube and search on "foam wing cutting". That will bring you to 8 minutes of the two hour video that a friend and I produced several years ago. Until I started cutting foam I never really knew how fast a basic CL model could be put together.

Buy an ARC and kit-bash it. VD~ ;D

I stopped by the LHS yesterday and got enough 5/32" music wire to jig up the wing in question, and I figured out how to hack up a 5/32" drill to make a clean hole in balsa. So I guess the wing's going to be jig built.
The plane's going to be a Sarpoulis "Pretender" from the May 1979 issue of Flying Models. It's supposed to be .19 sized, and I've got an OS MAX .25. I'm hoping that at 390 square inches that'll be enough plane for the engine.

Hope you have a lot of supports for the 5/32" rods. I use 1/4 steel rods from my local hardware store. Hardly any flex over the 3 foot span. Peice of brass tubing to join the two rods for a full wing span. In other words 4 rods total. Keep us posted. H^^

Stay off the net,and build a wing. >:D

Asking questions on the net is what I do when I can't get my body off into my shop!

I plan on making lots of supports, yes. I gathered from reading posts on this group (hopefully correctly!) that Brodak wings are set up for 5/32", so I figured
that was as much of a standard as I'd ever see, so I'll go with it.
It seems like everything that I looked at locally had a bit of a bend to it, except for the wire from the LHS -- and if it does have a bow, at that size I can shim it out.
Work is progressing. Now I need to ask "what's the quickest way to clean off a workbench" !!!

Hey, tim I know how the asking questions goes myself. Hope you took it as a pun no harm inteended.

It is called a floor broom. Like the ones they used to use in schools for werrping floors. LL~ LL~ LL~ LL~ H^^

Tim,
When I came back to the hobby I bought Dick's original "Pretender" for a quick start. It was powered by an old Fox .19. It was plenty of power believe it or not! Remember the name...It's Pretending to be a large(ish) stunter!

As to the quickest way to build a wing... Send Hunt a check for 300 bucks!

The quickest way to clean off a work bench is to finish the job in hand, get the trash can and actually ask yourself, "do I really need this gadget, whizmo or whojit"? Then either toss it, or place in a drawer full of "I might need it one of these days".
Right now there's a Nobler on the bench, with a halfway fixed nose (from the first @#$% flight!). I think I may have missed the building season on this one.
But it's raining heavily, so maybe not.
-
I think as americans wehave a problem with the things we keep because we might have a use for it someday.

But, did he get the Nobler fixed? ???

I found out that Top Flight Econocoat is made with an adhesive that dissolves in exhaust residue. Grr. Since I'm coming to stunt almost from zero, I'm retiring the Nobler until I'm a better flier and will be learning on profiles until I can make a plane last long enough to justify making it pretty.
I ended up with using a jig-built scheme, using two 5/32" rods. It's going slow, but that has more to do with the practitioner than the method. As usual, I think it's going to be ready to fly just about the time the weather closes in for the winter.

Quickest way to a wing: Buy a sheeted foam unit from from Bob Hunt. ;D

Hi Tim,
Are you having fun building that wing? I bet you are so don't worry about how long it takes you to finish it. :##
A question: Doe the wing have LE sheeting? If so, you might want to try a tip I found. Wet the sheeting with Windex and then pin the sheeting to the wing while it's in the jig. Let it dry and take the pins out. it will be shaped to the LE pretty good and will glue down with less chances for a warp. Kinda like making molded leading edges. ;D
Keep on posting progress! And most of all have fun. y1
