MPC Lambda Payloader Build, Part 9, Masking The Fins

This mask is different. Normally on a model rocket, the tube is white and the fins are a darker color. This one is the opposite - darker body and white fins.

   

Left: A strip of marked tape is cut over twice the root edge length. 

Set the tape strip down the root edge with the other half of the strip overhanging the top of the fin for now.

Right: With the body turned over, roll the strip under the fin. Keep tension on the tape and lightly pull as you lay it across the fin. 

Left: The body is upright again. Roll the tape over  the root edge making the edge as round as you can while still keeping the tape sealed (stuck) around the top.

Lay the tape down the root edge.

Right: Roll the tape under the trailing edge like you did on the other side. Lay the remaining tape across the fin race.

The two pieces of overlapping tape leaves an open  "V' under the trailing edge where the bottom of the trailing edge touches the tube.

A final piece of tape covers the tip of the "V" squaring off the trailing edge joint.

Paint and the results in the next post.
