For example: Neil's recurring trouble with this rocket has been separation of the half rings from the pylons/fins. This may be due in part to the ring's being made by laminating bent wood.

An upscaled ring could be made from sonotube, with a fiberglass wrap if you like or just a soak of the epoxy resin (making pseudo phenolic). Also, it would be wide enough to notch halfway across and interlock with similarly notched pylons. Once the interlocked notches are glued and filleted, you will not have the same problem Neil has had.

Will you have a different problem? Probably, but that'll be easier to deal with too.

Are you reading my mind? Thats exactly what I have in mind.
 
Repair #2 is now mostly complete. This time I used BSI 15-minute epoxy.

The first one was quick and easy. The second one required some clamping. I finally figured out to do this:

I forget and important Rule and attempted to clean up an epoxy drip with alcohol:

Alcohol + Future = clouds

I'll need to apply some more Future over that wing when it's all done.
 
Aaaaaand a bit of Future brushed on over the wing and every thing is back to shiny.

(that's a reflection in the middle part of the wing, not clouding).

This repair looks good and feels solid. Of course, so did the last one, and the original build. One more try!
 
I have learned over the course of my BAR career that I really do not enjoy making repairs to rockets. Therefore I will go out of my way to anticipate weaknesses and try to mitigate them, even if it sometimes leads to overthinking or overbuilding.
I just inadvertently noticed this bit of text in the first post of this thread. I suppose, having written it, that it was inevitable that this would become my *most* damaged and repaired rocket.

Sometimes even overthinking and overbuilding isn't enough!

I think that is very far-reaching. When building a new design, “going where no (hu)man has gone before“, beating a new path, trailblazing, exploring, doing research, starting a business, exploring a new land, experimenting, one is bound to encounter the unpredictable. And that’s part of what makes any of this fun! Rocketry is an affordable way to do this.

Good point, Alcubierre is a quite unique and non-standard design. Just imagine if you hadn't done as much overthinking and overbuilding! It may have even needed more repairs.
 
I'm not sure. :oops: My launch-tracking database is not fully up-to-date.

But I would guess not, because COVID came shortly after flight #2 and my launch opportunities since then have been scarce. I'll have to get it back into the flight queue once I get caught up.
