Re: Boomilever B/C

Does the speed at which the sand is dispensed affect how well a boom does? Because I've always just assumed that if a boom can hold 15kg it will hold 15kg no matter what. Also if the bucket tilts it shouldn't matter, right?

Re: Boomilever B/C

Hi, I have a question if anyone can help us with. The base of our boomilever always comes from both the tension bars attach point. Its kind of glue failure. It does not break, the whole base pops out. Our whole boomilever stays intact most of the time, this is mostly our failure point. We have trie...

Re: Boomilever B/C

I've noticed some people talking about a trapezoidal design for the compression members. How would you put bracing on the sides of the trapezoid?

Re: Boomilever B/C

What are some good vertical members I should try. Right now I'm use 1/16x1/16 balsa, and my vertical members are bending/breaking at ~7-8kg. 1/16" square for main compression beams? That's kinda thin. I'd use at least 1/8" square for a modified tower chimney design, or 1/2" by 1/8" for a regular on...

There is the option to have a narrow base with the end on the wall flaring out in a similar manner to the base of towers in 2018.
I just don't like the idea of have two parts on my boom. I feel like it would make it a lot weaker, but it is worth a try.

Re: Boomilever B/C

Any tips for the base. Since with 8cm width requirement the base that I used to use won't be viable anymore since I was using just a small piece of bass then laminating it. ( Used narrow booms last year )

Re: Rule 5a.v.

Wait if the part of the boom touching the wall has to be wider than 8cm does that mean that the compression members will have to be diagonal (kinda) to hold the 5x5cm loading block. Im kinda of confused how thats gonna work. Any suggestions would be helpful.
