As I said above, "you can use really low density...."
You'll have to try/see where that gets you.
A pair of bass 3/32nds, at 1.5gr/24" should be about 2gr.

definitely gotta try that...

I think this may have been discussed before, but does anyone have a good design for the base connection? My boom can hold about 10 kg, but it keep falling off at the base. The entire rest of the boomilever (tension members, compression members, trusses) stays perfectly intact. My current design is just to glue the base on, then add a couple of pieces to hold it place. Does anyone have any suggestions? Thanks in advance!
Edit: typo

I trust that you mean 10kg not 10 grams.
I would help if we knew how you build the base itself.

So basically, I make a rectangular base, and then I just glue it onto the tension members. Then, I cut out thin rectangular pieces that are the width of the tension member (made out of the same material of the base) and I cut them so that they fit like a puzzle next to the rectangular part of the base, so that the entire thing is like a rectangle. When it breaks, the thin rectangular pieces fall off.

You might want to drill a hole in the wood first

Yeah, I have a hole in it. Of course I have a hole in it. But that's not where the problem is. The problem is in the connection between the tension members and the base.

Were saying you should make a hole for each tension member as well. Have you read Aia's boom guide? It has descriptions with pictures of how to build a good base.

Well really if you make a snug fit, and lie the edges of the tension up with the washer, and glue generously with ca it really won't break.. And yeah the tensions must be drilled into the base not just glued on

But I do do that, and it still breaks at about 10 kg.
