Has Anyone created a homemade ceiling mounted "platform" for their projector yet?

I just discovered that my throw for my Proxima DX3 may be much too short than my current Sharpvision setup.

I'm thinking about putting a flat of wood, and suspending it with four short cables/rods that are mounted to the Ceiling. The Proxima's are 5 lbs, so I don't think there will be anything close to a weight problem here.

How low are you going to hag it? I had mine on a temp hanging platform in my basement while I played with the room setup and I found that my projector wouldn't Keystone adjust enough when mounted right side up. When I mounted it upside down it worked great. PS. I am sure that any rod you could buy would be strong enough. The only thing that would bother me would be the lack of stability on the platform. It would have to swing in the breeze. If it were me, I wouldn't want my stuff moving at all, but I am anal.... Just ask my ex-wife...

My ceiling mount consists of the following.

1. stud
2. ceiling fan support bracket w/ 2" lags supporting it.
3. 14" 1" threaded pipe downrod one end attached to the ball joint at the ceiling brakcet.
4. 1" pipe flange attached to downrod
5. 1' square mdf board
6. bolt pattern on bottom of my projector allows it to be mounted to the mdf.
7. 1 bag of BB's used for final adjustment.

I have a steeply vaulted ceiling and this has worked great for me. Once I figured out the correct length for the downrod and got it cut to length, my only adjustment when I mess with the projector is to move left and right. I also use the BB's for a final adjustment of the vertical positioning.

hope this helps

I built a ceiling mount out of plywood and 1x3s. The projector, an Infocus LP350, has 3 holes for screws on the bottom. I have a small piece of plywood attached to the bottom separated by some rubber spacers for ventilation. The 1x3s attach the projector to the ceiling and the setup has good rigidity. I initially had the projector about 15" from the ceiling, but that turned out to be too low so now it is only about 7" from the ceiling. The ceiling is drywall, so I used drywall anchor bolts for the attachment there.

Not sure what holes are in the bottom of my Projector since I don't have it yet.... Comin on the 20th! WHOO HOO!

I like sstieferman's idea of using a Ceiling Fan mount. I think I'll go to Home Despot or Revy to check out what they have for hardware.

I found out the MAX distance I have for my screen will have to be 17.20 feet. That sucks, cause using a rough calculation, (my body is 6 ft, and I laid down abour 3 times and a bit) heheheheh... my current FP is about 20 plus feet away.

*SIGH*

Hmmm.. maybe no one will notice a foot worth of overspill!!!!

Oh yeah? I have a swinging platform mount... with a 9" color gunned 220lb CRT projector. Ihave 275lbs hanging over my head. So there. I have huge dent in my head, as I am still getting used to the projector being there...when I walk by. At that weight, when you whack your head, it doesn't move much..I heard my teeth *clack!* together when I impacted. The projector wiggled a tiny bit... I said several bad things, and staggered about the house, and watched the fluid seep out of my forehead...

OH MY GAWD!

Hahahahah.... Are you by any chance 7 ft 3 inches or sumefink?

No.. I definitely do not want that type of setup in my living room. My present setup is quite unobtrusive, and I'd go as far as to have "bombay" type doors installed so that it would whoosh out of the way when not in use.

Actually, I am 5' 6" tall, and the projector hangs over the couch, fairly low, so it remains centered enough to get the top/bottom focus clean enough to actually use the thing. It is on a glued double 1/2" platform (two glued together is much stronger than 1 single 1" thick platform, when you do that, you are going up against the TENSILE strength of the MDF boards that are stressed together... much stiffer..It is still warping just slightly)

It's a big beast, but I'll take the quality any day over the convienience. I can deal with the technicalities of the gear (CRT), so It's a bit different for me than the average folk.
