Simple is good.

How about a crib for some of the more detailed minded folks. Maybe something like having the rivet pattern printed on the cardstock used for the fin can wrapper?

And now in a shameless attempt the threadjack this discussion, how would you recommend adding rivet details?

I printed a lot of paper parts and basically I am going to see about doing rivet lines from the "inside" on the paper. There are a LOT of rivets, screws and bolt heads on this thing.

I have been working on this project whenever i get some free time. A lot of redrawing diagrams and CAD drawing from all of the pics and information I can accumulate.

So far the hardest part has been the transition. I can make one as perfectly as is possible for me. The problem is which method is the easiest and most efficiant to duplicate them. So far I have been given a ton of ideas and come up with a bunch myself.

I just have to find the "best" one!

There will be a lot of paper wraps on this thing...more than I first though, to simulate all of the panels and a TON of rivets. Again it's a mater or which method is the most efficiant.

Here is what I've drawn up so far. I'm sure there will be a lot of changes before I finish.

More pictures later.

It's been cold here so i was putting off turning the rest of the parts but i finished those today.

So I had to put it together to see how it looked.

I love it! Beautiful work from the master, Sandman!

OK sandman you have hooked anotherone. Count me in for a couple of these kits when they are ready. Where do you find the time.

I've gone on to a new obsticle to overcome. The fins.

How do you get that nice diamond cross section?

The white one uses a cardstock skin glued over a balsa wood frame...It's OK I guess. It would allow mw to embose the rivet detail along the leading and trailing edge.

The solid balsa wasn't too bad to do...but it wasn't easy either! It does require the use of a belt sander and you have to hold the part just right.

The balsa and paper frame fins are I'd say equally difficult to do.

OK, maybe this isn't really that important. I just wanted to see if I could do it.

I also show a pdf of my fin CAD drawings for the paper fins.

Anybody else want to try and make a set and see how they come out for you.

Sandman,

I don't mean to sound like a broken record here, but this looks like another prime area for a vacuformed piece. Maybe a thin, rivet-embossed, pulled skin to be glued down over a balsa core. That way the core wouldn't have to be perfect, just "close enough" around the edges to fit inside.

Well, it's come up a few times already so it looks like I may have to make a vacuform machine.

One suggestion for these fins - start the cores with plywood, either A/C grade or just lite-ply, and glue some balsa "filler" over them to take up the empty space. Use the plywood to form more robust TTW tabs than just plain balsa.

Craig, That's exactly what I did on this rocket:


Sorry I don't have a close up of the fins handy. But the core is 1/8" aircraft ply with 1/8" balsa laminated over that. It made it easy to put a nice bevel job on the fins, too.

The rocket still turned out kinda butt-heavy. But that's the nature of upscaling model rockets, I guess.
