ASP Micro Hawk Build, Part 2, Engine Block & Kevlar Tie

You are supplied with two brown couplers.

Mark one coupler at 1/4". With a sharp knife, cut off the 1/4" end to be used as an engine block.

I like to restore the round shape and press down any burrs by rotating the block on a sharpened dowel.

The Kevlar line is tied on the engine block. Pull the knot to the top side of the block so the tied bulge won't contact the inside of the body tube.

The coupler is marked at 3/4" for a depth gauge. 

Note the top of the coupler was rounded off with 400 grit for easier insertion.

Slide the block into the long tube, no glue yet. Push into position using the long coupler up to the 3/4" pencil mark.

The inset picture shows a small amount of glue on the tip of a Q-tip. Insert in the back without touching the inside of the tube. Wipe off the glue at the engine block / tube joint.

The picture looks like I'm holding a Camel cigarette.
