I would definitely try the mini DeWalt clamps, then. Would you mind sharing with me what "special solution" you are using through PM? I understand if you don't want to, it's ok.

If you use the purple cyanoacrylate glue, it sets in 30 seconds or less.

Re: Boomilever B/C
Is it absolutely necessary to use glue stronger that bsi like gorilla glue for the base or is bsi good enough from a competitive standpoint?

Re: Boomilever B/C
So far I’ve been using bsi glue and it works fine. But I’ve ordered some wood so ill tell you how it goes with the gorilla glue.Cow481 wrote:Is it absolutely necessary to use glue stronger that bsi like gorilla glue for the base or is bsi good enough from a competitive standpoint?

Re: Boomilever B/C
I'm probably going to be building the two sides separately, then lacing them together in the middle on my old towers jig. Aia recommended doing the compression part first, and then attaching the tension members, but I'm going to take an approach similar to what I did with towers last year since that seemed to work out.

Re: Boomilever B/C
Are you doing a chimney type boom, would it be more efficient to make only one side of a chimney but add more weightMadCow2357 wrote:I'm probably going to be building the two sides separately, then lacing them together in the middle on my old towers jig.

Re: Boomilever B/C
You said that you were going to build two separate sides and attach them using a jig kind of like last year but that would mean you would have a boom box design according to the scioly wiki. I thought that the most common and efficient design was where you use only two compression beams and bracing in between.MadCow2357 wrote:I don't really get what you mean, can you clarify?Cow481 wrote:Are you doing a chimney type boom, would it be more efficient to make only one side of a chimney but add more weightMadCow2357 wrote:I'm probably going to be building the two sides separately, then lacing them together in the middle on my old towers jig.

Re: Boomilever B/C
To save weight, you will need a truss for a beam.This will need lateral support at both the top and the bottom, thus a variation of a box beam. Read all of last years postings on towers by Balsa man. (unfortunately now deceased)For a rather in depth analysis of the stresses imposed.

Re: Boomilever B/C
Oh, no I'm making a normal boomilever. I'm simply going to be building the two (vertical) sides first, then standing them up and lacing them together on my tower's jig. Like imagine two sheets of cardboard. You stand them up on opposite sides against a 5 cm (width) X 5 cm (width/length) X 50 cm (height) block, and then you use masking tape to secure the two sides together. Basically, the sides I am referring to are the two sheets of cardboard. I will lace them together once I have finished constructing the two sides.Cow481 wrote:You said that you were going to build two separate sides and attach them using a jig kind of like last year but that would mean you would have a boom box design according to the scioly wiki.
