I have not done anything on any of my builds since late March.
On April 6 I underwent Open-heart surgery.:dark:
1 valve replacement, and double bypass. This was totally unexpected & has screwed with my life quite a bit.
I have been out for just 3 weeks and started my re-hab today.
So until I am cleared to build stuff again , everything just sitting in Limbo. I think Airfest in Sept could be my first launch if everything goes well, so we shall see..............
Cannot lift arms above my shoulders, or weight over 3lbs etc..etc....etc.. No driving till june/jJuly. List of stuff to recovery is long as arm.
But to answer....I have much to do to finish this & my other builds. [2-stage Nike-Apache & Punisher 2 -stage rebuild]
Fit the I/S coupler...add all electronics & recovery etc.... I will document when i do it. Just pulling the lever on my drill press is a no-no right now.
Was hoping to fly a high thrust 2 grain 54 [J-460-T] or Warp-9 etc in booster and a 6 grain white thunder in sustainer...for shakedown flight.
After that a 6Xl whatever I can buy, at the time for booster [L-935 hope] to a 38mm Mellow longhorn in sustainer.
That should kick it in the butt.
Jim, as said by others, best wishes for a speedy recovery. When you're back on the air, I've got a question about how you set up your sustainer/upper section.
I am building mine single stage, so I guess I'll be sitting at the kids table this year. But I do want to shove an L935 in there. And I want to use positive motor retention, vs. just tape. I'm willing to friction-fit a DMS motor but I don't want to risk loosing cases. I will use the Aeropack CTI forward closure adaptor on top of the motor, and I will fabricate a forward retainer. My plan is to bond a bulkhead at the right place in the tube, With a slightly oversized hole in the bulkhead, the threaded rod from the motor adaptor will project into the upper compartment, and I can secure it from the top side.
I don't have an L935 handy right now (every time I get one, it disappears into my Darkstar 3, and then the Darkstar 3 disappears for a couple of minutes and comes back with just a spent liner). CTI's specs show the case (not including the thrust ring/rear closure) as 25.14" and the charge well on top of the motor extends another 0.6" The Aeropack retainer is another .625" (5/8ths) for an overall length of 26.37" overall. So if I mounted the bulkhead at about 26-3/4 from the bottom, I'd have a bit over 6" of open tube on top of the bulkhead. The AV bay/coupler will fill 3" of that space, leaving around 3" of a 54mm tube to hold the shock cord, the attachment hardware, a small drogue and blanket, and a deployment charge.
Does my plan and the dimensions I'm citing sound right? Anything I'm not thinking of?
I can tell you what I am thinking--an L935 in a 4 pound rocket? Oh Hell Yeah!

Och! that's brilliant.TIP:
1 Fin gets a couple drops of CA to hold on airframe after aligning on pencil marks.
This keeps fin guide in place while tacking on the other 3 fins with epoxy till cured.
No more having stuff slip-sliding all over the place, while trying to tack/glue fins in place.
Then break off the CA'd fin. sand root clean & airframe. Acetone wipe.
Re-attach with epoxy to airframe, while using the other 3 fins to hold fin guide in place.
I'mm .....baaaackkk!
Or you could just do this:This is why I always want my first flight low enough to see all events.
