Enerjet by Aerotech Strong Arm Build, Part 9, Filling The Tube Joint

Here's the tubes together, the coupler inside glued together using 15 minute epoxy.

The pencil lines are lined up before the glue sets up.

 

Most of the joint gap was first filled with CWF, the excess smoothed out using a single edge razor blade.

The picture shows the joint after the CWF was sanded to surface.

The high spots end up fuzzy after sanding.

I wipe on some medium CA Super Glue using a Q-tip applicator.

After it dries, sand using 400 grit on a block.

A final fill is a shot of filler/primer and sanding with 400 grit.

Taking these extra steps, you shouldn't see the tube joint seam on the finished model.
