As everyone seems to need to say in balsa building forums, please read through all the forum posts for this year's boomilever thread, and the previous two years for towers...

i tested my newest boomilever and it got 1720 ! it was 7.5 grams and held 12.9 kilograms. i feel nats will be at least 2200 to place in top 6

How does one add vertical bracings that connect from the tension pieces to the compression if the tension piece is not parallel to the compression piece, as in the 2 tension pieces come together to one point?

Not entirely sure what you mean, but I'm assuming that you're talking about connecting the tension members to the compression if the tension members taper inward to the point? In this case, a normal connection wouldn't work, normal as in everything is perpendicular and generally in the same plane. Haven't tried this before, but you could try shaving off a length of corner on a main compression beam, and rotate the main tension members so you could make a secure connection. You would then be able to make a "normal connection", except that member would be slightly vertically tilted. Does that make sense?

I'm not sure if shaving off part of the compression beam would be the best. Do you think it would be possible for me to just use very thin bracings and just bend them to fit? This would probably not offer lots of compression strength in the vertical bracings though, but I mainly just need the them to hold the compression in place and hopefully not bend as much.
