I am amazed by the way you got that balsa to bend that far all the way to the pointed tip. Even with wetting it. It would have cracked if it was me trying it :)

-Bob
The trick is to stick the tape to the wet wood while it is flat on the bench and then use the tape to wrap the piece around the form. The tape acts like a backing and helps to keep the wood from splitting. Also make sure the wood is really well soaked. Give it a try, it's pretty fun!

Oh, and leave it at least over night. It's kinda like a pizza I guess; if you let it cook all the way it's great. Take it out early and it's mushy and disappointing... 🤪

The guidance receiver fairings are sorta finished... The rear bulkheads were cut and installed, then they were fitted by wrapping some 320 sandpaper around the tube and sanding the mating side until the contour matched. Then the fairings glued to the payload tube. I still need to figure out the rest of the fairing details, but at least they are in place.

I also (finally) got some primer on the main fins. I'm going to get a few heavy primer coats applied, sanded lightly in between, then some rivet details will be scribed into the primer, followed by a light primer coat and color...

As always, thanks for looking, more soon...

While obsessing on all of the various little details and fiddling with tiny bits of balsa and ply, I have started to think about how I want to set up the av-bay. My initial design was a typical coupler with switch band type, but that has changed a bit.

My new idea is to get rid of the switch band and, since the booster and payload bays need to be lined up correctly anyway, using short bits of 1/4" carbon tube as indexing pins to align the booster and payload tubes. The carbon tubes would double (triple?) as pressure ports and holes for pull pin switches.

I don't think it will cause any issues either functionally or for set up in the field. Wadda you guys think? :dontknow:

I'm also planning to do this type of installation inside the bay...

The seam in the coupler his is because this one was a retrofit for another rocket. The seam was so this particular av-bay would fit inside an existing coupler.

The threaded rods will run above and below the sled keeping them out of the way of the various wires that run about in the bay. It also leaves a several acres available to mount the alts, batteries, switches, anvils, etc. securely to the board without having to work around the rods and lugs. It also lines up the switches dead-on with the ports.

Haven't cast anything in stone yet, but I do need to start getting serious about the functional part of this build (finally:rolleyes:). Going to order a thicker wall coupler and some glass or aluminum bulkheads here in a minute. No matter how things end up I'll need those things...

Thanks!

Mike

Sounds interesting, but I'm not quite able to picture it. I'll be curious to see what it looks like.

Space is good!

Well, I finally got the main fins primered and the rivet detail scribed...

First, I made a template out of (you could probably guess) 1/64" ply. The holes are drilled so that when the edge of the template is aligned with the edge of the fin, the line of rivets will be the proper distance from the edge. No measuing required! Made things go a little quicker... Then it was just a matter of taping the template in place and using a little needle file to scribe the rivet heads (I used every other hole to get the right spacing).

I now have no more skin on my fingers, but the fins came out pretty good! The purpose is not to make perfect rivet heads (that is better done with a piece of tubing), but to make it look like flush rivets that have been painted over. Real missile boosters have an operational life that is measured in seconds so they aren't really fussed over, finish wise. Some of the rivets will end up buried under paint, some will be more prominent, some in between. Scribing them into the primer give this sort of random effect. The next finish coat will be color.

The main fins are now (FINALLY! It's about time!) ready to be glued to the booster! :cheers::cheers::music1::music1::headspinning::dancingelephant:

Once in place I will make some fin attachment brackets; they will be easier to build in place.

In addition to getting the fins done, I managed to get the rail guides glued on, got filler and primer on some of the surface detail stuff, and finished up some small conduits on the upper tube. I'll get some pics of that stuff tonight.

Started on the av bay too. I tried to describe what I was doing in an earlier post with little success, but the pics should clear that up too.

As always, thanks for looking...

Well boys, it has fins.

Yeah, well, I know you know that; y'all have been looking at nothing BUT fins for lo these many months...

But they are all attached now... :oops: Yup, all twelve fins are actually GLUED to the rocket! :cheers:

So to celebrate this auspicious occasion I present, in it's entirety for the first time anywhere, Mugsey's over-finned, over-detailed, over-worked LOC Precision Nike Zeus/Spartan!

Seriously though, thanks to all of you who have stuck with me so far. As is often said about building race cars; 80% done, 80% to go!

As always, thanks for looking!

Looks great! When you get done, do some beauty shots and send them to LOC. Might get on 'the cover of the rolling stone'! Well kit cover art anyway. :)

Looking most excellent! Rivets like that scare ne a little because of a too thick paint coat or having a spray go bad and needing to sand and recoat, etc, etc. You are a much braver man than me :)
