Building the Semroc Sprite (part 4)

This isn’t normally painting season, but I want to apply and sand primer on the body and flat fins before adding the ring and fin tips, and I don’t want to postpone further work until May. So, after some cursory wood filler application on the fins, I took room temperature paint and rocket out into…

Building the Semroc Sprite (part 3)

The dried contact cement is… improved. Might never be beautiful. These days if I can remember to I prefer to glue launch lugs on before fins, so I did that. Much easier to line it up without fins in the way, especially these fins. These unshaped fins. The instructions specifically tell you not to shape…

Building the Semroc Sprite (part 2)

Start with the motor mount which, by volume at least, is nearly the entire rocket. The motor hook goes on the outside of the body tube, and then the Tyvek piece gets glued over that. (It was gauze in the original K-15.) I tried using yellow glue for that, but the Tyvek didn’t seem very…

Building the Semroc Sprite (part 1)

For its winter project, the Syracuse Rocket Club is making Sprites. This isn’t a group build of a single rocket but individual builds of a single design: the K-15 Estes Sprite, or Astron Sprite as it was first known when introduced in 1964. Looks like its first catalog appearance was 1966. I suppose if any…

Building the [scratch] Pumpnik

If you’re looking for trouble, you might find it in a dollar store. I dragged a piece of ST-7 tube out of the stash. Cut off three pieces, punched a hole in each of two and two in the third. I also had a couple of 18 mm balsa blocks about an inch long in…

Building the Semroc Blue Bird Zero (part 2)

I finished putting the Blue Bird Zero together. I’ve forgotten, have I ever used the alternate top piece of the fin alignment tool? The one for narrower tubes? Maybe this was a first. The spirals were pretty tight, so I decided to leave them for the filler primer to deal with, but I did fill the…

Building the NewWay Too Square (part 8)

Look, in my defense, I tested the Testors laquer over the Duplicolor primer. And I tested the Rustoleum 2X black enamel over the Testors laquer over the Duplicolor primer. The one thing I didn’t test was the Krylon clear coat over the Rustoleum 2X black enamel over the Testors laquer over the Duplicolor primer.I’d sand that…

Building the NewWay Too Square (part 7)

Hey, did you know Testors lacquer dissolves plastic disposable cups?Me neither. By pure blind luck it wasn’t over anything important when the bottom let go. Anyway, I put the stuffer tube in. There’s no rear centering ring; the tube’s held in place with internal fillets on the fin tabs. Then I brush painted a bit of…

Building the NewWay Too Square (part 6)

I gave the nose cone an Elmer’s treatment, then primed and started sanding. Discovered a problem. The sides weren’t as flat as I thought. This side had an especially low spot in the center, but really all the sides were higher on the edges. I did a lot of sanding to get the sides flat (or…

Building the Semroc Blue Bird Zero (part 1)

This is the last of the kits I bought at NARCON last year to be started. I’ve always liked the Blue Bird Zero’s looks and decided, standing there in eRockets, I should have one. I’ve since thought of a couple possible kitbash ideas, so maybe I should have several, but I don’t and I’ll build…
