Installing The Motor Mount:

The two pictures above left & center show the completed internal fin fillets viewed from the aft end of the rocket between the now installed motor mount and the body tube.  In those pictures the epoxy has not yet been applied to hold the motor mount in place.  But in the next picture (above right) shows the forward end of the motor mount where you can see the epoxy fillet bonding the motor tube, centering ring and body tube.  You may have noticed the cables are gone now.  My TAP advisor convinced me that the forward end of the motor was the correct mounting point, which I was planning to use in addition to the cables.  But since I was somewhat concerned about their unruly nature, Tom didn’t have to work to hard to convince me to cut them out.

 

Well there is plenty of work to do, including electronics bays, the aft small control fins, and more motor mount epoxy work, but I have mounted a forward small rail button mount, as well as forward and central larger rail button mounts.  The aft rail button mounts will be drilled and tapped through the tail cone / retainer ring.  I will then have two small button mounts, which I intend to fly with.  But options to quickly install larger buttons should rail availability call for it.  The central 3rd button is for a little heavier duty work that this rocket may some day inherit.

 

At this point the rocket looks like this:
