Used Titebond II to attach nose cones. I now have a sealed system!!!

Weather permitting I will do an ejection test next weekend.

I need to do some cleanup and attach fins, but that will wait until after the test....

Jerry - I owe you an apology

I took the rocket (without fins) and set up a static test with a 30" thin mil chute. Had to do some jury rigging to install a 24mm load (CTI E31). CTI states their 24mm loads have 0.6g of BP for the ejection charge. I strapped the rocket to some benches, and 3 - 2 - 1 - 0 and nothing. Bad ignitor. Replaced it and tried again.

So what happened? I expected the charge to go off but the cone to stay on, or even if it came off the chute to stay in the tube.

What really happened? The chute and cone came off quite energetically!

Now the cone is a bit on the loose side, but I think good enough to satisfy a safety inspection.

I did not try a 29mm (which comes with 1.2g of BP). I guess my options are to fly with 24mm or to use a 29mm and remove some powder. I can also run a test case with a 29mm - I ran out of time today....

U.S. Rockets motors use 0.4-0.6g BP 3F depending on diameter, but this refers to 24mm, 29mm, 38mm motors SU and RL.

I understand CTI and AT include more BP than is needed. I suggest using a used pill bottle to collect extra BP for secondary deployment charge use. Separate by 3F and 4F please. Use ONLY BP not "alternatives".

Started the first batch of production Tridents. Just a couple parts remaining and on the way from a vendor.

One of our vendors, BMS is on a 7 MONTH lead time right now!!

it's alive....It's Alive....IT'S ALIVE!!!!

Time to resurrect this thread

Again, I apologize - the last year and half has been "difficult".

I did make progress, but had limited time to download pix and update this thread.

Forgot to show the application of the fillet



Showing how the tubes are tied together with screws

The Trident would not fit in my normal paint area, so I built a special stand from PVC to allow me to paint it as one assembly

Cleaned up primer plus some more F&F

Hmm - the order of the photos (and orientation) don't match how I loaded them - sorry

White and decals....

Good thing I made the rocket to separate - otherwise this is how it would fit in my car..

Still needed to paint the motor tube rings....

I was able to fly the Trident, along with an Estes Clone (the smallest) and a Hawk's Hobby (middle size)

On the launch pad, launching, and successful recovery!

Tridents are an inventory item now. Still working Orion 3 and Athena 3.

http://v-serv.com/usr/kits/trident_2.25.htm

$129.95 each + $12 flat ship per order. That's a low price for so many custom balsa cones.
