Semroc (Estes) Starship Excalibur Build, Part 14, Details
I didn't realize there was a fourth fin vane when the fins were re-cut. This extra vane is glued over the longer, rear launch lug. The designer went out of his way to hide the launch lugs.
This extra vane had to be filled, sanded then primer filled and sanded.
After the tube had seams filled and the body tube primed I felt a glasseine overlap on the tube. It's not something you would see until the white coats are sprayed.
CWF was brushed on and sanded. A brushed coat of CA glue followed to lock the CWF in the shallow step. After the CA was sanded smooth the step couldn't be felt.
The engine mount is glued in the rear. The lower centering ring is recessed about 1/16" from the tube edge.
After the glue has dried inside on top of the upper centering ring a fillet was applied around the rear ring joint.
