The Silver Comet is assembled and sealed and is in gray primer.

Now for the fold over:

I apply Aleene's Super Tacky to all places where the armature touches the card stock and then.....

.....you might think there would be NO WAY that I could over-engineer the next part, but.....

.....now for some technique:

After folding over the obverse half of the fin card stock and before the Aleene's can grab, I arrange (4) wide strips of scrap balsa and clamp them down with clothespins so the fin will maintain it's shape while the glue dries.

After my dinner I remove the braces and inspect the fin. It's good enough.

I then press Squadron White into the void of the outer edge. (BTW, what ever happened to Squadron Green? I can't seem to find it anymore.) I'll sand it off later.

(1) down, (3) to go!

Performed a very similar technique last week (three pairs of balsa strips held with light duty clothespins) when gluing the fin skins on the Estes Little Joe I. Worked great and held both sides of the fin skin against the balsa core structure evenly all the way around.

I thought about getting and using the Aleene’s based on your past recommendations, but wound up using 30 minute epoxy. Doing the final trimming and sanding on the fins now.

The build is coming along nicely, Jeff.

As for the putty, Squadron changed the formulation some months ago, in an effort to arrive at a finer grained, easier to work with, filler. Something more comparable to Tamiya putty, in my view. Unfortunately, that initial new formula also easily separated in the tube, resulting in quite a mess when you opened the tube and squeezed it. Those complaints led to a further refinement in the putty, and the latest formula is not so bad. Finer grained, dry-sands better than the old stuff, doesn't wet-sand quite as well (in my opinion), and doesn't have the stiffness of the old stuff, which, depending on the application, can be either good or bad. I liked the old white putty, and frankly wish Squadron hadn't messed around with it. Of the latest new versions, I prefer the Gray. There was a new Green one, but briefly - I've not seen it around as of late.

That said, it may all be short-lived. It seems Squadron is shut down, and it's unclear whether this is a temporary shutdown, or permanent. At least I've not been able to arrive at a clear answer. The search for the perfect putty/filler continues...

Back to Jeff's excellent build.

Thanks! A few posts ago I was asked about the Silver Comet.

It's in gray primer and above my desk. It's been dry for days now and it awaits white primer. The Semroc 1B next to it awaits it's second coat of white primer but both will have wait until I can paint outside again. Temps will be single digits for the next few days and I just don't trust the paint in frigidity like this.

The other (3) Nike fins are now braced and drying.

I've sanded the 4th and last coat of Deluxe Products sanding sealer from the nose cone and transition. The first photo is the raw application of wood filler days ago and the second photo is how it looks tonight.

The only reason I don't use 30 minute epoxy to assemble the built-up Nike fins is because the Aleene's is VERY thick and VERY clingy which almost guarantees the armature won't shift as I'm laying the braces. Also, on rare occasions I've had epoxy soak through cardstock--especially at a crease where it's been compromised. I've never had a soak-through with the Aleene's.

Nice touch, that.
