that moment when you realize your life sucks sometimes

Facts lol.

Sorry this is spam...

i dont think so
but big facts lolll

Show us the money... let's go to the videotape! Until then... it's all just shop talk.

Since the eyebolt of the loading block needs to pass through the boomilever to attach to the rest of the loading assembly, this means that there cannot be bracing where the eyebolt is. If this is true, then doesn't the boomilever depend on the strength of the last 5 cm of the compression member? The only way I see to brace the boom is with ladder bracing or by extending the length of the compression members-- thereby adding unnecessary weight to the boom-- and having the eyebolt pass in between 2 X braces. How are you guys adding bracing throughout the entire length of the compression members?

I haven't really encountered any issues with this, I just skip that part and brace normally. I suppose you can try adding two ladders around the region of the loading block. I do that with 1/8" by 1/16" ladder pieces, and I haven't encountered any issues..

You mean that it is ok to leave the last 5 cm of the boom without bracing at all? I was thinking it would drive down the score since booms would snap at the 5 cm point away from the distal end... or is that why the tension members are so important??

From my experience, yes, it is okay to leave the last 5 cm without bracing. Normal x bracing, that is. I had a breakage in the last 5 cm on my third boomilever, and I ended up adding two ladder pieces to help take some load. I also rotated my main compression members (rectangular) so that they were longer vertically. Haven't that kind of breakage since, so I suppose what I did helps. If you want @TheMadScientist PM and I can send you a picture or two of what I changed.

Well someone took my username...(Kinda. Welcome to the forums ) From my experience you should focus more on the distal ends if you want results so I wouldn't panic over the bracings yet...

I would think you shouldn’t just leave out the bracings but there should definitely be a balance. But the bracings should be strong enough to allow some warp I guess. If it’s too thin/weak it would snap.

I am unsure of the specs of the J-bolt listed on the rules. https://www.amazon.com/National-Hardwar ... B000BO54X8
Can anyone who has this confirm that the length from the wall to the inner part of the "J" is about 4.5 cm? (2.5 cm opening plus an inch of just the "J"?)

Yeah, it's like like 4.5cm +/- .1

Would a 1/4" diameter wooden dowel at 3cm suffice butt-jointed between 2 bass tension members at 1/8x1/16?
