I have the same problem. I have decided to build my base using 1-1/2" pipe and fittings. I envision making an I shape out of pipe and tees. The center tee will be left lose enough so I will be able to adjust the  plumb and have holes drilled into the legs so I can pin them to the ground. Then use my guides. I am only going about 12' or some, so I hope I will be able to raise the center pole by myself. Don't know if this is will work or not, but when the weather gets warmer and the ground drys out. I'm going to give it a try.

The problem that I have with the center pole is this.

 

The star and CLS top (tie down connection point and pulley) adds a weight to the top of the pole. As you try to raise it, you quickly get past the balance point. Without someone holding the lower end, the top comes crashing back to the ground.  I am dealing with a 20' center pole though.

 

If you try to lower it by yourself, you are already past the balance point before you start, and it is not possible to lower it gently.  This happened to me once before I realized what was happening.  I was lucky that it didn't ruin my star.

 

If you stick with the CLS base, it is farily easy to put up by yourself.

 

If I understand what you are describing, it sounds like it will work.  The CLS base is just a cross, the I shape sounds like it will allow you to get it straight in one direction.  As you raise your center, one side will tighten while the other loosens.  Probably not a big deal becasue it is only turning about a 1/4 turn.  As long as you use guy wires you will probably be ok.  It might be a little interesting getting the guy wires set without it coming back down.

 

I highly recommend using guy wires with turnbuckles.  If you skip the guy wires, you will probably regret it at some point.

 

Here is the anchor that I use.  http://www.truevalue.com/product/3-x-30-Inch-Storage-Building-Red-Earth-Anchor/9527.uts  They come in different sizes and can be set low enough so the lawn mower doesn't hit them.

.Those earth anchors are great. But, in my yard I have to use a pick just to plant flowers. Every-time it rains, I get a new crop of rocks. I've lived in this house for 30 years, and they just keep growing. I have to use rebar that I drive in at a pretty steep angle. If I hit a boulder, I have to move the anchor point. I am thinking about building me a portable hole and build it with the center on an angle. I'll wait and see what happens.

But even a portable hole needs to be staked to the ground. At least thats what he showed us a few years ago when he came to the HAM meeting in KC. indi, maybe you should be using those devices that rock climbers use. Either the pins they hammer in or those spring loaded ones they put in cracks. Didnt know that it was so rocky down around J.C.

I'm going to resurrect this thread. I'm gathering all my supplies I'll need to build for this year. I'd like to build a mega tree. Due to a limited number of channels, it'll likely be static this year, but that's fine. I want to use the portable hole, which looks easy enough to build. I was also planning on trying to build the Monkhouse Jump tree. Since I've never built anything remotely like this (while I'm not a complete idiot, I haven't done a lot of handyman building in my past), I was wondering if there was a step by step build instruction somewhere? The instructions on the website give a lot of diagrams and some pictures, but not a "step by step" walk through of building it from scratch. I want to make sure I'm doing this right, both for safety and visual appeal purposes.

If you're going less than 20' you can use This and just use 2 sections of rigid conduit. Your center pole will need to be 1 1/4" and then make the mods to the portable hole. Use 1 1/4" stuff instead of 2". It's what I'm doing this year.

I am going to build my first mega tree this year and have really liked all the info on this thread. The one thing that I would like opinions on is for whether or not to support the light strings. I plan to use 70 count m5 leds that are aprox 23 feet long and we do have some wind in the

Columbia Basin. Should they be supported by 1/16th cable or something similar?

Thanks,

PMK

not really, as long as you have guide wires in the middle and at the top you should do fine (3 at each location).  Mine is 20ft and holding up 48 strands of C6's, we had a couple of days of strong winds (so strong we had to take our inflatables down) but the tree handled it.

PMK,

 

Back a few years ago I was reading a lot and researching the best I could on the subject of Mega trees. Seems that I was coming across post of people talking about the wires stretching and then the copper inside would snap. But not all where complaining about this. I am German (2nd gen born here in the states) and got a lot of my build it strong and twice needed specs from my Grandpa. Also I feel like I am one of those people plagued by Murphy, kind of like Jimswinder.  So, yes I used the 1/16" cable with a green coating of some sorts. And wire tied my Red, Green, and White super string to the cable. Did a little loop at the top with the cable and did not run the wires over the hook head, just the aircraft cable on the hook to minimize strain and wear to the wires.

 

Thats what  I done and it works for me. Easier to find the center and dont have to worry about any change to that point of center either.

another bump on this.... have used the CLS 20' kit (& the 4 guy wires) for 3 years now. live in tampa fl area, so no snow but few good thunderstorms, its held like a champ! modified the PVC base a bit to fit my liking, but its all based from the kit. i have 6400 minis + 25-30 strobes on tree and works fine, its is poss to set by myself, but usually get few family & friends (bribe with food if needed) and have everything up from storage to fully running in half day. tear down takes me about 5-6 hrs solo if i have to (again bribe with food). biggest problem is storing 2 10' steel & few 10-12' PVC poles. GREAT set up and looks awesome, easy to adjust.
