Boomilever B/C

Would it be worth it to laser cut my boomilever? People on my team did so last year but their design wasn't hugely effective.

Not really. But it's an interesting concept. You're better off hand building it.

Another noob question!

Is there a way to avoid having to bend the tension members so that they can be closer together where they attach to the j-hook?

Try gluing your tension members inside instead of outside the boom. It’ll help with the tension bend

Just to clarify,
Has everyone come to a collective decision that the best glue to use in the compression joints is the Bob Smith Medium CA (the purple bottle)?
I was thinking of trying some booms with the thin Bob Smith CA (the light blue bottle), but I just wanted yall’s opinions as well.

So it all depends on the type of joint that you have to glue. If it is a reasonably large overlap between two pieces, use the purple because that will partially soak into the wood but not disperse so much that there is no hold between the pieces. Use blue when you want to fix a thin (ex: 1/16*1/16 square) piece that broke somewhere along its length. Basically, use the blue any time you want the glue to get between the grains of wood, and then push the grains back together thus getting a perfect bond. Use the pink glue when you need to fill gaps between two different pieces of wood. The purple is viscous so it will not be absorbed by the wood as well so it will leave a sort of "bubble" on the wood or will fill the small space left between two joined pieces of wood.

Do you by any chance any way for the application of the blue CA just a little bit easier?

The problem with laser cutting is that all the grain still runs the same direction. Sheets of balsa are surprisingly weak when tensioned perpendicular to the direction of the grain, and they split. This tends to occur primarily on where the diagonal bracing would be.

What is the best way to connect the two tension members near the hook? I've just been putting a single 1/4 square piece under, but it seems to fall off every time.

this rule is adding a whole new factor to the build. kinda annoying lol. I miss the old rules.

What glue are you using, and is the 1/4" balsa or bass?

That's SO for you - if the rules didn't change, old teams would just dominate again.

kinda struggling reaching 2k, anyone got any tips?
