The lower picture shows the contour after some sanding. There is more sanding needed, the penciled sides are still showing.
Here's a good fit of the wide root edge over the curvature of the BT-55.
On the forums, David Scigs has mentioned the Krylon Industrial Acryli-Quik spray paint is the old, original formula Krylon. I eventually gave in and ordered four cans from Grainger's. I had to drive across town to pick it up.
David was right - it behaves like the old Krylon. Please note - this is not the Krylon you find at WalMart or Home Depot.
The great thing - it dries fast and you don't have to worry about re-coat times!
It may not be as opaque as Rusto 2X, but I'm tired of cottage cheese rough finishes.
Note - this gloss paint still dried flat when sprayed in humid conditions. We did have cooler weather a few days ago and I got a great gloss finish.
More CWF was rubbed in and sanded smooth. Another coat of filler/primer, sanding and another white coat.
How to paint the slot just aft of the fins?
ReplyDeleteIn some past builds of this rocket on TRF I asked the same question, and the answer was that no special effort was made. Whatever got in there during normal spraying was it. I was pretty hard to see in there.
DeleteOne possibility to improve it slightly (maybe) would be to black-Sharpie the inner surfaces before gluing the fin assemblies together.
Interested to see how Chris handles it on his build.
Hi John,
DeleteLike Neil wrote, I didn't do anything extra. Some paint did get into the open slot, you really can't see that far in. It's a good point, maybe I should have sealed the interior balsa surfaces.
I like this rocket a lot, and am enjoying the build. It's really making me feel guilty that I scavenged mine for parts and never built it. All I have left are the transition and the fins. Maybe one day I'll resurrect it.
ReplyDeleteSo tempted to try the Acryli-Quik but the fact that it is so expensive and also hard to get is discouraging.
Hi Neil,
DeleteThis is almost a "resurrected" build. Two were picked up cheap at a Hobby Lobby clearance. I had already opened the kit using parts as an example for an Apogee P.O.F. newsletter article.
Chris, Luckily in SoCal I don't really have to worry about the humidity. I know it is a little more expensive, but well worth it. Also I can use the whole can, where the big box store paint I end up throwing away the can before getting halfway through the can.
