Have you considered turning the Jawstand head 90 degrees and then centering your tower over the stand's center axis? I'm not sure how deep the head is, but that may alleviate any concerns that you may have about the tower being offset.
Looks great! You've got lines holding it in place, and you can always stake it down through the holes in the bottom of the legs.
How about a build thread? Or at least a parts list? I have a jawstand, but I've just got a 1/2" drill chuck on an "L" bracket and a 2 x 4. One of these would be great for getting into competition builds!
looks great, my only concern is that the 5' lengths of 1x2 "select pine" may get a little toasted at the bottom. If for some incredibly unlucky reason, the rocket sticks and doesn't launch, the flame may set the wood on fire.

I wouldn't worry about binding as much as I'd worry about one side flexing more than another and the rocket coming out at an angle. I would suggest supporting the top section as well.
You could always build a halo ring that at least binds the top section together. If you used two tie-ins for each support, then tied all 3 together, it should be stiff enough.
That's somewhat similar to one I built. The most advanced tool I have is a drill press so I keep stuff basic as well. What I haven't been able to do is come up with a design that allows for fast adjustment of diameter and finally have decided a dedicated tower to each size is the easiest way to go. I am now looking at designs that are easy to disassemble/assemble for transport.I built this contraption for a 38mm minimum diameter rocket with a J motor. This is my first attempt at a launch tower. All materials are basic Home Depot stuff. Seems sturdy enough. Comments? Thanks!...
If you're worried about that you can plasti spray the bottom foot of it and it should be fine. After all, they spray engine exhaust manifolds and they turn out fine.looks great, my only concern is that the 5' lengths of 1x2 "select pine" may get a little toasted at the bottom.
