Help with a Falcon 9 Octaweb?

Hi all,

This is a great group, lots of really helpful techniques.

I'm working on a Falcon 9 MOC, and I'll be basing the entirety of the model on how the booster's engine core (octaweb) ends up looking like.

The (x8) symmetry of the outer ring of Merlin engines is a headscratcher on the smaller scale concept. Many designers have built Falcon 9's at various scale, but none with a design that works for me satisfactorily. At the larger scale, things get easier, but the likelihood that it will ever be built IRL decreases a great deal.

Looking for thoughts and ideas on how I could make some of these intricate connections that make up the octaweb of the rocket.

Have you considered this part as a start? Maybe with 2x2 thrusters instead of the large 3x3s or the smaller fez pieces.

I'd thought about that previously, but if I used modified plate clips like pictured below, the corners will clip.

Just file those edges right off...unless you are a purest like me. :)

The only thing that comes to mind is stacked Travis bricks turned 45 degrees from each other. Then you could use headlight brick or some other brick with a stud on the side to get eight studs pointed up close to each other.

Hmmm. Not bad at all. Don't know why I hadn't thought of that. Let me see how the rest of the rocket would scale.

I think that would work without the 1x1 round plates irl. Would technically be "illegal" but only just.

Can't be THAT illegal, since I made it in LDD without hacking it...

Yeah upon closer inspection looks like it is 100% legal. Those little clip plates have more clearance than I thought.

It didn't work with regular 2x2 round bricks for the thrusters. This conical things are just the tiniest bit narrower.
