Can I use rocket tooling for gerbs?

[Rando]

Any reason for me to use gerb specific tooling for gerbs if I already have the same size rocket tooling? How different are they? I realize I'll have to use an appropriate formula for gerbs, and not rocket fuel.

Gerb insides are a multitude of shapes. Some have a shallow core like a whistle rocket, some have a parallel core with no comp at the bottom. LOTS depends on whether you want 2m or 10m height with 1 second or 1 minute duration. Some light st the top some at the bottom.

With that in mind, there's no reason I can't make a few and see how they work, at any rate.

Thanks for the video. I have Caleb's econo rocket tooling, I'll make a couple and see how it goes.
