Leaping Arches

Recommended Posts

So we embarked today on creating 4 Holdman style 20ft 9 channel leaping arches. After 5 hours and way into the dark we have completed one of our arches. The assembly is much more time consuming then I would have ever imagined. Props to everyone who has previously made them, i owe you a little more respect.

On another note, how have people handled supporting the weight of the lights while assembling, specifically after you have covered sections with light. We tried chairs and shoe boxes but our drill wasn't powerful enough to overcome the friction. Twine from the ceiling? How do you get it not tangled?

Have you done any research on the "sleeve" method of arches? That is what I use and it is so much easier to make and repair.

Agree completely. This is definitely the way to do it. Even though you already invested time in the making of the first arch, I would think you would still be way ahead by converting to the other method. Even if it doesn't save time now, it helps in other ways too. These are much easier to store since you can break them down if needed. Much easier to repair, since you just repair the single sleeve that is out--and can have a spare sleeve ready to go if this happens while the show is going.

Some refer to these as Harbs Sleeves, and their creation was first discussed here:

The lights on your arch look great.

I also agree with the others on the sleeve construction.

I did this with big mega arch and the smaller arches in my display and it rocked. Storing in a plastic tub, done, stored.

If a section goes out, you can have another section handy, and quickly and easily replace it.

Also for the 4th show, I was able to reuse the smaller arches and slide them on a pole and create a straight up pole with 5 channels, and it worked great. When done, put them back in the plastic tub.

I wrap 20' poles in 1 piece with support in 2 areas of the center. I like doing this way because I can put the zip cord under the lights. I have 7 sections on my arches and 6 sections on my mega tree. Here is a picture of 1 of the support sections. All made from stuff in the garage. I use a momentary foot switch to control the motor. I got to where I could build a pole with the zip cord on it in 1 hour.

wow great advice! i am very interested your casters setup, that might be just what we are looking for. I like the sleeve idea but for now i think we are going to stick with the one inch tube method. thank you all i will post back with results

I had done one "traditional wrapped" arch, then tried the sleeve method.. I will NE-VER go back to long pole wrapping again!! Sleeves rock!!

Here is the first video of our arches. We made them the old fashion way, which believe me was time consuming but i am so happy with the finished result.

Gents,

Thank you for this thread. I just completed my CCR arches, and was about to begin wrapping 3/4 grey PVC with incan minis for the rest. Yesterday I went and bought more grey PVC to make sleeves, rather than arches. Several of the suggestions led to this decision but the three that stand out most to me are: they fit in a storage bin, they can be used fof both arches and a straight up pole, you can have a spare handy for easy replacement when a section goes out.

Thanks again! ...and just before build time, perfect timing... :D Time to go cut some sleeves...

Jeff

Jeff I cut my sleeves at 16 inches with a 5 degree angle at both ends so when they go together on the PVC main sleeve they sit tight together, I don't know if you cut yours yet so I thought I would throw that out there. :)

Congratulations Kevin!
If you are tight on Channels, I put 2 next to each other and mirrored them using one set of channels for both.

As for the sleeves, last year I made the long poles. But I'm probably going make a few more next month and will try the sleeves. Big factor for me is that I can quickly swap out a section IF it goes out.

Does anyone have any pics of sleeved arches at night with a traditional arch as a comparison. I just fear that a sleeved arch will look like a bunch of straight segments in an arch and not a smooth curve.

Best thing to look at is some video. I don't have a comparison to the traditional arch (but there are plenty online). I too worried about the segmented look, but found during my testing that they didn't have that at all. The sleeves bend some, and the lights on the ends of the sleeves blend just fine with the adjacent sleeve, so you can't see the break.

Here are few to view:

There must be at least 4 feet of snow on these arches. :P;):D

This was my first prototype last summer, recorded only about 10' away from the arch:

the ones i are were non segment. we just hung them in the garage for storage, and though it was a little tricky, with 2 people helping lift really not all that hard. and they fit the 20ft length of the garage. I'm pretty happy witht the end results

Should also note that on my arches in the videos above, that they are 7 channel arches, 10' long, using sleeves. Each segment/channel has only a 50ct string of warm white LEDS on it.

Brian, here's my sleeved build, night test. Each 7' arch has eight 11" sleeves, tightly wrapped with 100ct minis. As you can see in multiple angles, there are no gaps visable in the arch, no "segmenting" either. it entirely depends on how long the sleeves are.. mine are 11".. if you use 16" like some others here, it might appear more segmented.. but not with "foot-longs". Realize too, that people stand at least 15-25' from most arches (on the sidewalk, or in cars) so the segments look smoother still.

This is a great idea for arches, and while I'm sitting here thinking about my display next year, I have to ask a few questions that I haven't seen commented on in all the threads around the Harbs sleeves.

7 segments on 10' sounds fine. That gives us the 16" segments and some left over. My question is, do the 100ct CDI strings work on these 16" segments? Assume using the 1" segment diameter.

I'm trying to figure out what I will need to order for next year, besides a bunch of controllers.
:D

:D

I am currently using 100 ct incadesants, not next year will be ordering the 100 Ct LEDS from Paul it seems to me that the incadesants go dark far to quickly, I to use the 7 sleeve method with 16 inch sleeves I spaced my rebar at 6 feet to give me a nice rounded look, works well for my display keep in mind every display is different, I am using one and half inch PVC for my sleeves and three quarter inch PVC for the main line that the sleeves slide over, I tried the one inch PVC and when I put everything up I noticed there was a bend in the arch that looked like garbage so after I made the switch my arch turned out perfect.

Hmmm, after some additional research, I might be looking at CCRs instead. It may actually be cheaper that arches with all those segments and controllers to run them.

Comments?

Considering that you can make any color that you want, this is a thing I've been looking at as well. I'm planning 4 arches using 2 controllers either way.

I'm also looking into using CCRs or CCBs for arches.
