Stuck some fins on the 5" diameter Big Daddy. Internal fillet fun up next. Also got the motor tube and forward centering ring epoxied into the Doorknob body tube.

Another project I'm working on is a scratch-built scale model of the Aries mashup that was the Red Tigress 1 mission on 8/20/91. Nothing fancy, physically. BT-60 tube, conical balsa cone. Rear fin shroud was a bit challenging, but not bad. Working on making decals in GIMP tonight I am deviating from scale by just going with one 18mm motor mount. I considered going with four 13mm motors, but that's probably risky on this and not a lot of good delay times worked with a 4x cluster. I have never seen a kit of this rocket, nor any other scratch builds. I love how this thing looks and can't wait to finish it up and fly it.

Ah, . Great tag. I'll pile in. Older pic from a ride at Levis Mounds in western Wisconsin. That's my awesome '18 Trek Stache in the tree. Does everything I throw at it.

Also sanded the filled spirals on the Doorknob body tube. These tubes were from my work, on their way to being thrown out. Got a ton of them. 61" long, 5.25" OD with 1/8" thick walls. Very beefy. Cost of nothing is even better. Got many other build ideas stewing.

As for spiral filling, I've gone to using wall spackle from wood filler. Doesn't shrink when it dries and sands very nice with 400 grit to smooth it out and not cause paper tube fuzzies. Goes on easier too and seems to stick really well.

Taking advantage of the time change to work on some builds. . Shaped a tip for a 5" Big Daddy nosecone form (will be fiberglass laid over), drilled vent holes in the Big Daddy tube and a 5" Doorknob. Now to reinforce the air foiled Doorknob fins with some epoxy.
