Estes Black Star Voyager Build, Part 2, Engine Mount

The shorter engine mount tube (Part A) is joined to the longer Part L tube. 

The low 1/2" of the Part A tube is exposed, covered by small cardstock vanes. I went ahead and filled the tube seam with CWF, then filler/primer and sanding.

The green coupler doubles as an engine block, butting up against the upper bend of the engine hook.

The fit was loose, I built up the diameter with some rings of wood glue.

The slit for the upper bend of the engine hook is cut at 3 3/32" from the bottom.

I used my aluminum angle to insure that the two tubes were in line as the glue on the green coupler set up.

The instructions say to mark the low tube 1/2" from the bottom.

The illustrations show 1/2" space from the centering ring to the low end of the tube.

The pencil line is 1/2" from the bottom of the tube.

I set the black retainer ring a little above the 1/2" line so the face of the notched centering ring will end up at the 1/2" mark. (See next post)
