Default Wing Rib Replacement

Hi All,

OK I've got to repair 2 ribs on a .25 UGLY STIK. This isn't crash damage though, I was working on some furniture and my compound miter saw launched a piece of wood up and through 2 ribs before the wing was even covered. (The wing was on hangers in the garage.) I'm posting pics so you can see the damage. My question is do you think I should cut out what is left of the 2 ribs or just "patch" them by replacing the missing area?

Thanks

Danny

I would just replace what was broke out. To replace the entire rib, you would have to remove the top spar or cut it. Just better probably to replace what was broke. I had a similar accident with a radial arm saw and a corsair wing. It really ticks you off when something like this happens.

Yeah.. you should be able to sand out the area that has the glue on it, then, if you have it, use the old broken piece of the rib as a template to carve from, then carve it, following the grain of the original, making it a tad bit longer than the old one, then fit it in and glue it. You could always put in a small piece of brace balsa on either side, front and back if you are skeptical of the fit and the glued end product.

Yeah I really didn't want to start cutting into a wing thats not even flown yet. I'm really just happy the saw didn't send a couple of fingers with the wood. whew!

I've still got the prints and plastic patterns I used to build this plane so cutting new rib sections to patch it will be no problem. I was just worried about weight and balance issues. I'm putting an 18 year old O.S. MAX .25 with a tuned pipe in it so I think it will still have plenty of power even if I add a few grams to the original weight. (This is an awesome engine, It sat in the bottom of my toolbox for 15 years then I pulled it out, took it apart and cleaned it, put in a new O.S. #8 plug and the sucker fired right up!)

It's my first plane built just from plans and not a kit and I'm a little upset with myself for damaging it before it's even completed. But I guess that's the life of a modeler. At least I still have 10 fingers though so it isn't all bad.

Since it's raining here in Nashville for the next 2 days I got plenty of time to get the repair done on this plane. Hope it clears up Saturday so I can go fly my PT-60 for awhile.

Thanks for the input guy's.

Danny

Hey, dandodge---- Throw your body in front of the plane. I've found bandaids are easier than repairing a plane Ha! Ha !

Cut a slit in the shearweb so you can exstend the replacement piece and glue it to the good front half.
