Anyone else building a frame for a 12 ribbon CCR tree?

Recommended Posts

Frank,

Does the star have a 3/4 tube frame also, besides the 3/4 pvc plate?

If you go to my web-site and look under the photo gallery under "building a 12-ribbon RGB tree", down at the bottom are pictures of the star frame.  The star frame mounts to the Tree frame and the PVC plate mounts to the star frame.  It may have been overkill.  However when I disassemble the tree, I have four bolts that remove the star frame.  It just made it easier to re-assemble later. 

 

 

Also I just posted some more pictures of my lightshow on the "photo gallery" page, that shows the RGB tree.

Frank,

Can you tell me what lights you used for the star, How many per string, and how many strings ?

Thanks,

Larry

Hey Frank, question. What software do you use for making those tree measurements you are sharing with us? I'd like to use your design, but want to use 16 CCR's instead of 12.

 

Thanks!

As has been mentioned previously, I wanted to rebuilt the attachment of the pixels for my tree.  I did that last January when I took the tree down, but could not readily update the photos on my website since I did not re-assemble the pixel tree until November.  I finally had time to take a bunch of photos and update my website with the new construction.  For a short description, when I built my tree in 2012, I ran 12 steel cables from top to bottom, and ty-wrapped the pixels to the cables.  This was never the intended mounting method.  For 2014 I split 3/4 inch PVC tubing and mounted the pixels.  I have finally taken some photos and updated my web page below.  I will note that as I type this my web server is having some intermittent issues, so if you can't get to the page, try a little later.

Frank,

       The bolts you used are they carriage bolts or hex head bolts ?  1/4-20 X 1-3/4 ?

Wasn't the aluminum tube quite expensive ?  I'm wondering if anyone has ever put a pixel tree on a roof?  My front yard is too close to the street and the side yards are either too narrow or obscured.

I picked up 19 tubes of 3/4 1/8" aluminum tubing from a local metal shop for $20 per 24' long stick. Not a bad deal. I had to pay an additional $100 for residential delivery, but it was well worth it.

If I recall correctly the aluminum for my tree was about $450 with shipping.  I've since found a local location that is even cheaper.  

 

I hang my tree from the peak of 2nd story and above the garage.  

You can see my mounting "hardware" in a series of posts starting here:

I used these:

and these:

Note: you need twice as many nuts as screws -- and longer screws if you have more than two tubes on a screw.

I did a similar system of hanging things from the roof, only I used 1 pulley that was a single cable running over the edge of the roof and tied off with a boat cleat on the roof.

 

My frame was made from Superstrut available at Home Depot and with all of the hardware I spent about $150.  The large A frame made literally has a cross member at the base about 6 feet in the air that I then set ½” conduit pipes on.  This is where the bottom of the 12 CCR tree is.   The conduit pipes are made from  2x 10’ lengths making a total of 24.  At the coupler in the middle, I used about 1’ of ½” threaded rod to keep rigidity.  At the top, I have a 2x4 piece of wood with ¾” holes drilled through them a the right angle. 

 

So assembly goes like this.  Bolt all of the Superstrut together in the A frame shape without the cross member yet to keep it light.  Bolt a Superstrut 4-hole flat bracket to the peak where the two side bars meet at the star point.   Run the cable over the roof and through the pulley to the 4-hole plate.  Attach the upper 2x4 spacer and the star at the apex of the two legs of Superstrut.   Pull the cable to make the A frame upright.   Attach the Superstrut cross member that has 12 1”x1.25” Beam Clamps attached at the spacing you want at the base of your 12 CCR tree.  Bring out each 20’ long ½” conduit rod that already has the CCR zip tied on to it and stick the top through the 2x4 hole and then put the base in to the Beam clamp and secure it by tightening the square head set screws.  Repeat 12x and then put your control box below the tree and run the CCR cables to the controllers inside.

 

It’s heavy, but solid as heck.  I did add two threaded rods with rubber bumpers near the peak so that the thing cannot bounce in to the house.  And I use a little armature wire to make sure it does not lean away from the house.  During the entire display, there really isn’t much force on the cable attached to the peak – it’s mainly just for balance at that point.

 

Total cost is about $300 including the cable, pulley, hardware, etc.

A couple weeks ago I posted in this topic that I had updated by web page to show how I rebuilt my pixel tree for 2014. I also noted that my web server was getting intermittent.  Well, a couple days later it completely died.  As of a few minutes ago, my website is back up (thanks Don), so you can see what I did for 2014.  When I took it down Monday I took some more photos that were requested and will be adding those in the next day or so.  I will also be adding a page on my CCPs in PEX arches.  Lastly, my video guy should have videos to me in the next week or so, so those will also be available soon.

Delivered: 3/4 X 3/4 X 1/8 21 feet long 15 pieces. And it was only 225.00

 

Also got my ss bolts in, but the ones they sent aren't threaded all the way down, so I will have to reorder them. I also got wing nuts to put this together.

I have my tubing, got my bolts, but I also ordered wing-nuts for the back of the ccr tree. I have also ordered a large star from Brian, had it special made. Bought a plastic tool box that has a seal around the top that will hold 12 CCR controllers and 2 power supplies. Now I just need the weather to get better. Thank you Frank for all the help and picture's. I will post pictures when I get started.
