Estes Orbital Transport, Kit #K-42, Part 9, Launch Lugs Alignment

The printed PDF tube marking guide probably wouldn't fit the BT-50H heavy wall tube. I went to payloadbay.com and entered the 50H diameter and an eight fin count.
This fit the tube perfectly. The tube was marked for all the fins with pencil lines.

OOPS! While I could use 4 of the 8 equal spacing lines for the lugs and main wings, it turned out that the Ventral Fins and Spacecraft Support pieces are not equally spaced!
Use the kit supplied fin space wrap for the smaller body fins.

TIP: You could just glue the dowel standoff onto the tube. I sand a very slight "flat" on the bottom of the dowel. It's a minor adjustment that gives a stronger bond.

I checked the alignment of the two lugs using my aluminum angle.

Double check to be sure the lugs and standoffs are sitting up straight as the glue sets.








The forward lug was glued on 8 1/2" from the front end of the main body tube.

The lug and standoff is right below the 8 1/2" mark.
