I suggest using 1/8 wood and X bracing to start with and move to 3/32. I suggest Loctite super-glue so much.SLM wrote:1. I am not sure what you mean by "paper jig." Are you referring to a two dimensional drawing on paper? Or, are you referring to a three dimensional form for assembling your tower?huhhyea wrote:Heyy guyss.
So I'm making a tower for division C and I really need help right now...and it would be greattt if you could help me.
cuz literally NO ONE has ever done a building event at my school. (including myself. *sigh*)
two questions :
1. When you're making PAPER JIG for your glue... do you just draw lines or the whole thickness of each wood? I need help on how to make jig in general!!
2. When you're making X bracing....how do you glue two wood to form X? like, would you pave to put the other wood or just sort of bend the wood to glue them together?
_______________________________________So basically those questions are really important__________
and these are optional questions...
1. I'm using Titebond II ultimate wood glue -- is that too heavy?
2. I'm using only 1/8 balsa wood. Do you think it's worth getting 1/16 for bracing?
2. If the X bracing has a relatively short length (say under 10 cm), it probably is not a good idea to bend one diagonal over the other. You may want to have one diagonal on one side and the other diagonal on the other side of the frame.
3. You can find lighter glue than titebond. See Entry 5 (2009-2010) here.
4. We have been using 1/16" x 1/16" for bracing without any problems.
Also, spend time reading the entries on this forum; you will find many practical tips for building towers.

Re: Build Techniques
1/8 by 1/8 low density would be better because its cross section is larger. To convince yourself on why this is true, just think about a 1g piece of 1/16 compared to a 1g piece of 1/8-of equal length of course. The 1/8 by 1/8 stick will easily hold more.

But I think someone said the opposite actually in another thread....iYOA wrote:1/8 by 1/8 low density would be better because its cross section is larger.

Won't 3/32 be better since technically it's a lot denser in terms of volume?

Re: Build Techniques
I think I may have confused myself then; I think it was that if the density was the same then the smaller one would do better. So basically what I understand is the 1/8 with lower density will do better? But if they are the same density the 3/32 will do better?Littleboy wrote:But then it gets too much weight. And 1/8 can still hold the right amount of weight and have no excess weight.
