LightBlockPanels Completed/Thanks for all the help
Posted 15 May 2007 - 06:34 PM
Panels purchased already assembled or kits (1 inch 40 schedule PVC & 10oz. fabric)
5 panels, with risers similar in size to what we made:
approx. $500 = panel kits + riser kits + (4) weights + shipping to CA ($70?)
approx. $750 = panels + risers + (4) weights + shipping to CA (150?)
5 Homemade panels
(2) 84in. X 52in. & (3) 76 in. X 52in., using 1-in./40 schedule PVC & 16 oz. Duvetyne fabric
PVC, Joints, Cutter, Glue, Screws, Washers, etc. - $120
Portable weights and Irwin clamps purchased retailer - $100
Material (16 oz Duvetyne) - $100
Total = approx. $320
You could easily shave another $65 off of that by not buying the portable weights and making them yourself. (We really needed something because we live in a windy area,) Also, you could buy less expensive material.
However with all that said, I am very pleased with the results. The dimensions of the panels are customized, specifically, to fit our needs. The panels fit together perfectly. The clamps work great. The panels are extremely stable in windy conditions. The weights work wonderfully, and the light blocking is incredible.
A hint about using duvetyne – It is made to block light, so it functions beautifully. However, it is difficult to find locally, so you would have to order it which significantly adds to the cost. Also, it frays at the edges, so I had to put fabric glue around the cut edges to stop the fraying.
The biggest problem associated with the project was purchasing the materials. It was difficult finding black nylon washers and the clamps, and we couldn’t buy the fabric, locally, etc.
This project was a lot of work, but well worth it. Thank you, for all of your posts! We definitely could not have done it without all of your help.
Pictures are included.

Jim makes a good point: many people would find an article on how you made your panels very useful!
Again, good job!

I started a similar project last year but haven't got around to it yet(I have all the parts). Your great post has inspired me to get it finished, Thanks.

We bought them directly from dark sky. Here is a link to a picture of them on the dark sky website portable weights
How do you have the weights attached?
In the picture you can see a hook attached to the plastic container. The hook (It might be made of aluminum.) is attached with a bolt and nut to the bottom of the container. The weights cost us $40 for (4) + $15 shipping. We had originally only planned to build 4 panels, so we bought 4 weights, but we actually built 5 panels. So, far, we have had no problems with the panels blowing down or sliding, but eventaully we'll, probably try to make or buy another weight for the 5th panel. It is very windy here on the Central Coast. They weights are pricey, but the seem to work well.
We bought from a couple of different places. Here is the least expensive of the two. Showbiz Expendables
Where did you get your duvetyne?

They definitely help with the glare. You can, also, try observing with a towel over your head. It looks a little silly, but it works. Another good thing about the panels is that it allows your eyes to get adapted to the dark. My eyes were never dark adapted, because there was a streetlight blaring down on me from almost every direction. The panels do add more time and hassle to your set up. It is probably only about 5 minutes, but they are arkward to move. That is the only downside that I see.
Do they really help? I have problems with street lights and neighbor lights causing glare on my eyepice, so I have been considering some panels.
