The 3rd and 4th stage BT-60 tube is glued on to the centering rings.
One half of the third stage is dry fitted to check for clearance and adjustments.

Then four pins are cemented into the four holes in one half of the third stage.

And it's all allowed to dry.

While gluing the first two stages a grid fin brushed up against my leg and the lower two glue contact joints popped.
Easily repaired, but this seems to be a point of concern for landing damage. Perhaps this is why two extra fins are supplied.
I wonder if it would be possible to 3D print a hinge and rod and glue the grid fin to that? Also would be more scale realistic. Up for display, down for flight.

A hinged grid fin would stand a better chance of surviving landing contact I would think.
More give, less damage.
Anyhoo, third and fourth stages get glued later today.

I think there is an unwritten Law of Epoxy:
No matter how careful you are, you WILL get some on you.
Or your clothes.

I managed do some epoxying last night on the WM Andromeda without getting any on me! (there, now I've just jinxed the whole weekend!). Once I finish that, I'll move on to my N-1

The display tower is finer resolution and fit the nose cone without sanding.
The stock tower had residue/flash stuck to it even after the support material was removed and required considerable sanding to fit.
I was wondering why there were 2 towers. (no, I haven't looked at the instructions yet...)

Trusses have been glued on. Initially I was going to use modeling cement, so I started sanding off the paint in the areas where the trusses contact the airframe. Glue to paint = not good, right?
But the instructions again say to use contact adhesive. The picture in the instructions shows Gorilla Glue contact adhesive. It is a clear, thick goopy adhesive. It also says the glue can be peeled off.
So I'm guessing it's similar to clear silicon adhesive.
Unfortunately as I mentioned Home Depot does not have that particular adhesive.
Fortunately I think I have something similar. It's called Foam2foam. I believe it's a silicone adhesive cuz when I roll the half dried glue on my fingers it balls up with that "silicone feel", if you know what I mean.
Anyhoo, that's what I used:
Lower trusses.

Upper trusses

There will be a gap in the lower trusses that you will want to line up with the launch lug hole

Same with the upper trusses

And the plaque.

A Top Flight 48" X Chute is scheduled to arrive tomorrow.
So I'm calling this build done.
Just need to do some minor brush touchup.

That is so ....Koo...!

Both N-1's a little pricey for me at the moment. Will consider the Soyuz once that's in production. Let us know how it flies.

This is very cool, but how likely to get 6 D12's to light as the same time?
I would think these are pretty reliable:

A fellow rocketeer just flew his here about a week ago.
Around the 9:03 mark:

A little squirrelly but no damage.

If I was building again new, I would consider replacing the BT-50 skeleton with a BT-50H.
(You will have to sand out and slightly widen the openings in the 3D printed parts).
My N-1 toppled over on the carpeted floor and the core got bent.
Will repair and maiden at the first opportunity.
I need a big field.
