(Slow Build) L3 The AGM Special

[jfcote]

I used the Payload Bay template generator to print the Fin Guide Tool. I glued the print on foam board. I also started the slow process of attaching the fins to the motor mount with the Proline 4500.

In previous posts I forgot to mention that I sanded all the surfaces to be glued with a corse sanding paper and wiped them with acetone.

The fines are now all attached and I started the filets between the motor mount and the fins. I mixed a 40 grams batch of epoxy, so 20 grams for each filet.

I completed the internal filets between the fins and the motor mount with the Proline 4500. I had some large gaps between the fins and body tube. I used West System epoxy that I heavily thicken with the West 406 Colloidal silica filler to fill from the inside of the body tube. I used green painters tape on the outside to prevent the epoxy to ooze out.

This week, I will work on my external filets and hopefully next weekend, I will install the last centring ring and the motor mount.

I will use screw switches attached to the side,

Wondering where you found the screw switch? I'm looking for one now to DD my Zephyr.
