FlisKits MMX Saturn V Build Part 2, Engine Mount

The engine mount is similar to a 18mm style, just smaller.
The engine block is set with an engine casing. 1/8" of the casing extends out the back.

The scalloped ring is set into the glue fillet on the rear centering ring.
The engine skirts will form and glue over the scallop circles.

The instructions tell you to notch the forward ring for a Kevlar tie.
There is a small hole already laser cut in both rings.
I used a small rat tail diamond file to clear the hole making it large enough for the Kevlar to go through.

I didn't knot the Kevlar but wrapped the loose end under the loop a few times. A knot might bulge the body tube, there isn't much clearance between the mount tube and mainframe tube.
This will be plenty strong after a glue fillet is added over the top.
