Estes Saturn 1B, #7251 Build, Part 8, Adhering Low Wrap


The 3M 77 adhesive will hold the wrap down, but the joint seams can lift.
I squeezed a drop of medium CA glue onto some scrap cardboard. A toothpick was dipped into the CA glue and transferred, directed down the seam edge. 
Immediately (before the CA glue can set up) a burnisher was pressed down the seam to seat the edges.


The butt joint seam is sanded with 400 grit wrapped around a soft cotton Q-tip. This gives you cushioned sanding.

A fin will be glued over and cover most of the seam. Pay attention to the low end of the seam which you can see on the finished model.

With the wrap lined up with the top of the body tube, there might be a little overhand on the back.
This was trimmed off with a sharp knife, then sanded flush with a sanding block. 

Build time:
Adhere Low Wrap: 20 minutes
Total build time so far: 6 hours, 5 minutes
