Mounting on a Vaulted Ceiling

I've had my Ampro 3600 for a few years now, and haven't had any problems with it in ages. Now I'm looking to make myself some trouble I guess.

The room I have set up is a bit awkward for mounting. It has a vaulted ceiling tapering down in height towards the screen. When I mounted the projector I ended up attaching it to the underside of a shelf at the high end, which made it close to regular ceiling height. However, it's always been too far away from the screen, causing me to run it at near minimum height and width. I'd like to fix that, so that I can get closer to the full potential of the projector.

I've seen vaulted ceiling adapters, like this one, but don't know if they'd handle the weight, perhaps with more than one?

I've also thought about getting a local guy to weld something up to adapt the ceiling angle to flat, and working from there.

Unfortunately, I believe I'll need to drop a couple feet in addition to the angle problem, so stability is also a concern.

Has anyone mounted a CRT on a vaulted ceiling? Any tips or other ideas?

Well, the only time I've had issues was actually something I caused myself. Just took a month or so of conversations with Curt to work out that I was the cause. Since then, haven't had a problem with it.

I've taken at least the red lense off, both to look for wear but also to confirm for myself that I wasn't using nearly as much raster as I should be. I've also looked through the lenses at the other tubes, and couldn't see any significant wear. There was very light wear on the green, but it wasn't in the shape of the current setup.

Picture attached, don't flail me, but I am correct that fixing the mechanical setup should improve image quality pretty significantly?

I don't have an original mount, I used unistrut to mount it and used the attachment points straight on the projector. I'll check with Curt on that one.

Actually pretty decent, I just know it's capable of much more and my physical setup is the limiting factor.


What kind of angle do you have on that ceiling? That looks to be just a standard unistrut setup, which is what I have now. Are the ceiling attached members shimmed to be flat or is the threaded rod hanging at something other than 90 degrees to the ceiling?

I know, it is tube abuse, but it was a matter of using it mounting it how I could at the time, or letting it sit longer. Temporary solutions always end up lasting longer than they should.

I'll take a look at green and blue, though through the lenses I didn't see much. I'll take them off and make sure I'm not going to regret moving it.

The roof rafters are a 12/12 pitch (45degree). I have a 48" flat ceiling that is somewhere around 13 feet high.[/quote]

Ah, so it's high but flat. Lucky!

Took the lenses off to get a good look. Well, now I feel like a proper jackass for abusing the tubes. Hopefully, it's not too bad.

The green tube is the worst. The picture actually looks worse than in person, maybe the gamma of the camera or something. Judging from Curt's Tube Wear Chart I'd put it at a 7 or so. Blue shows just a slight amount of wear, and I can barely make anything out on the red tube. That said, how bad would this look if I moved it to the proper position?

No, I can't move the screen forwards any more, in fact it's already been done. I have about 10" of dead space behind the screen.

Anybody have an opinion on how visible the wear mark would be?

Thanks
