Be sure the edges of the Reduction Wrap are smooth and have a consistent width. This will effect the fit on the large tube edge.
I wrapped some 220 grit around the BT-101 tube and ran the edges over it.
The Third Stage Wrap was applied first so I would have a straight upper edge reference for the Adapter Wrap.
The adapter wrap was Set in place over the card stock adapter.
Notice the lip overhang. If it is applied correctly it should butt up clean against the Upper 2nd Stage Wrap.
After some test fitting there were a few minor high spots on the wrap edge. These were lightly sanded with 220 grit on a block.
Sand and check, sand and check.
Here's a pretty good fit of the wrap and the upper tube edge.
There was a slight gap at the seam. Slivers of left over plastic sheet was glued into the gap.
The fill strips were sanded. Any remaining lines were masked and hit with some filler/primer and sanding.

That's a pretty neat trick using slivers of leftover wrap to fill in those gaps. I wish I'd thought of that.
ReplyDeletei took a small piece of electrical wire and laid in the gap to add another rib where the wraps fall short
ReplyDeleteHi Metal,
DeleteAfter building a few Saturn V kits, I've learned to cut the wraps wider than the corrugation ridges, wrap around the tube, mark and trim them to size. Still, I didn't get them close enough!
