Estes Laser Lance #3218, Part 2, Engine Mount

The engine mount assembly is standard.

Notice the green centering rings. Most of the green wrap was sanded off for a better fit in the BT-55 main airframe tube.

A rounded top dowel was used to put a line of glue inside the tube at the height of the upper ring. Note the dowel is set at the upper centering ring and marked at the bottom. The pencil line at the bottom represents the low end of the BT-55. The low ring will end up even with the bottom of the tube.  

The picture above on the right side shows a line a glue around the top of the rounded dowel.

The dowel is set in the tube up to the pencil line. Roll the glue around the inside tube making a glue bead.

Slide in the mount, not quite into the glue bead. Apply some glue around the top edge of the lower ring. Slide in the mount, even with the tube end.

Here I'm pressing the mount in using the flat face of my sanding block so the low ring and tube edge are even.

Some CWF filler was brushed around the flat end and sanded smooth. If all goes well there won't be any seam edge after the filler/primer coat later on.
