Thanks. I don't know if I am violating anything

but if I am I will finish building, get pics, and get a video before I take it down.

To help the wind problem you could put some

re-enforcement rods through the green spine (track connectors).

What an ambitious project this is? I have confidence

that you can do it, especially if you made that 17.5 ft TTD.

[ssfan313]

I have to ask how will you reach it 13 feet above your

house because i dont think putting a ladder on your roof is a good idea.

[FunkMaestro]

Wow! Your neighbours are gonna be thinking:

"What the hell?!? WOW!!"

[KnexMan200]

I

am going to prefabricate the tower. I will make a 30 foot tall metal support that can be

in the middle of the tower. I will lay that on the ground and build the tower around the

metal support. I will also put the track on and zip tie the Knex tower to the metal

tower. This is still all on the ground. To make it vertical I will have someone hold the

bottom of the tower and I will tie a rope to the top of the tower. I will go on the deck

with the rope in my hand and I will pull the tower up. Hopefully it won't break or

fall over when I do this.

[Westside7th]

How are you going to make sure the pole

doesn't fall over? You could dig a hol 3 feet into the ground and cement it like a

basketball hoop.

[coastergeekrtc]

Right now I am having a little bit of trouble deciding on

what to use to support my tower. My dad says wood will warp, the plastic pipe will

bend, and his idea of a metal frame will coast about $100. I don't want to

pay this much for a metal support that I wont used again. Does anyone have a

suggestion. I was going to have the Knex tower one red pole wide and one red pole

long and 30 feet high.

[Westside7th]

When I was planning on building the tallest coaster, I

had two plans. Build the coaster up the side of my house up to about 20+ feet and

then use K'NEX for the rest. Or, I was going to build a K'NEX tower on

top of my 9 foot tree fort so the tower would'nt have to go all the way to the

ground. Why don't you just build a K'NEX tower from you balcony and

up but then have a metal pole between the ground and baclony for the bottom part.

[jmrtc89]

Im baaaaaaack....anyways

Why don't you just build a K'NEX

tower from you balcony and up but then have a metal pole between the ground and

baclony for the bottom part.

Because he wants it to be free-standing, other than just placed some where, or

hooked up there. Plus, the thing will get more speed this way.


I say

you tie several cords into the ground and to the tower, like those tall anntennas you see

when you drive down to knotts berry farm and the dlr. But dont just support the top,

you have to support it all they way down the tower. I'll try to draw a pic, if

necessary.

[coastergeekrtc]

The thing I am worried about is that the 13 feet of

tower wont support itself. (13 feet from my roof to 30 feet in the air) I need something

to hold the tower at the top and I have it figured out. I am using the sewage pipe.

[gforce]

You could use cables or rope.

[nitro9003]

If you can you could get a strong PVC pipe, stick it in

the ground and build on that.

[jmrtc89]

If you

can you could get a strong PVC pipe

PVC pipe is strong in width, but not lenght. After 7 feet of pipe, it starts to

bend. After 30 feet, the pipe bends so much, it would knock the tower down.

[Westside7th]

You could always make a small wooden tower with a

couple of boards. If you nail it together correctly, it could be pretty strong.

[FunkMaestro]

I do hope you find a way. The wooden tower

doesn't sound bad Westside7th, but you could also do something out of steel

pipes or something...

I have decided that I will make my model in the

summer. Right now I want to relax over the winter break. I am also starting a raw

materials model that I have been planning for about a year now.
