Old Time Stunt Can Have It's Downfalls. Literally.
« on: October 06, 2019, 12:34:40 PM »
Well, it happens to the best of us.  LL~

Sooner or later, better later, you damage a model. Sometimes it's beyond repair, but in this case I decided to do the fix.

I do have quite a bit of work ahead of me because of the paint detail and graphics.

All cleaned up with all covering removed to expose the damage. Not all that bad actually.

Let's see, now where do I start?

Alignment the easy way. Eyeballs and straight sticks.

Trailing edge was glued first, temporary spar only pinned in place. That'll be removed to slip ribs over then Epoxied back in place.

Paint stick for a straight edge while LE dries. All 5 minute Epoxy. Good vision makes for better alignment. It's a flyer so I'm not all that fussy. Probably a half hour so far, not counting the removal of the covering and minor fitting.

LE, TE and the spar are in place. One thing left is a strip of thin ply on the LE and TE at the joined area. A bit on both sides, just to be sure.

Repairs could eliminate the tip weight.  LL~

Spar is marked for baby-back location, Ribs, 4 of them.
Masking tape is for rib shaping.

Baby-back ribs the easy way. Possibly.  n~

More material than you need between the inside rib and tip rib. Mask off both and sand away with a long "T" bar. You do have to pay attention to what you're doing. I got 10 minutes here with the vacuum underneath.

Thin ply in place at TE and LE. DONE! Bottom side tomorrow.

Moving fast.

Possibly the outboard wing will survive the next cartwheel.  LL~

Now wait a minute! Not being critical, but flat amazed at the concept. Why not cut new ribs from plan templates or tracings? That is how I repaired my shattered Scientific P-40 wing.

You mean you used the existing/remaining ribs with blue masking tape as "templates" to sand the new ribs to shape on station?
How do you keep from having the sand paper cut through the tape and into the existing ribs/covering?
Or is your sanding stick just long enough to have paper only where the new ribs are, but none where it glides on the existing ribs?
If the latter, then I imagine you short-stroke your labor so the sandpaper doesn't hit the tape.
 I'm trying to understand if/how your method could have saved time. I can definitely see how it would truly capture the appropriate shapes if the ribs wound up only so close to the original stations. I do see how it allows a lot more flexibility if new/scabbed-in spars have to be relocated from stock.
I will say I now have another "tool in the toolbox."

I'm looking forward to seeing the finished repairs. Will you be rebuilding for flying with "battle damage" or trying to restore the finish/appearance? She's looking good. Thanks for sharing!

If the 'new' ribs are oversize then the sanding block never touches the existing 'pattern' ribs till they are near enough to size / shape. The addition of the blue masking should I guess equate to the thickness of the sandpaper so new should equal old. Its an interesting technique although i'd rather not have the need to utilise it LOL!

Thanks for the reply.

If this was new construction I would have made the ribs as per the plans. I don't have the plans to this model.

I've used this "tape at each end method" many times over the years for many models.

The Gee Bee Z for example, the kit I bashed had just enough ribs to get by. The ribs I added, for a more scale appearance were oversized, tape prevents the existing ribs from being sanded. Beat the tape up simply replace it. I start out with two layers.

Yes, the "T" bar has sandpaper from end to end and I sand right over the tape area.

A time saver because one can quick cut rip material and stick it in place quickly.

I did the wing to the Stuka this way. The half ribs I added to the Flite Streak 007 I did this way, same with the Mig-3's half ribs. Gotta remember, I'm used to doing this. I'm gifted in all facets of various types of model building.  LL~ LL~ LL~ n~

I will restore the finish as best I can. It's been 4 months since the damage, so heartbroken it took a bit of time for me to get around to the repairs.

WARNING! WARNING! WARNING!

Silk applied using no dope.

"You are about to enter another dimension, a dimension not only of sight and sound but of mind. A journey into a wondrous land of imagination. Next stop, the "No Dope Zone!"

I applied silk to the bottom of this wing dry using only CA. Tight as a drum! Took only minutes AND it's ready for the first coat of dope.

Still taking notes, and holding my breath. You are definitely moving through reconstruction!

Wing top tonight, I'll do it during a commercial so as to not miss any of the show.  LL~

And I discovered I have no Sig dope thinner. This puts a stop to things. Bummer!
