|
Anyone know this off-hand? I'm not seeing it in the NEC manuals and want to pick up all thread at my work's machine shop on the way to my buddies -- hope to finally install Don's machine at his place today! Is it 1/2-13 or something smaller...7/16 or maybe even 3/8? These are the four mounts on the corner, not the little ones I see a flange mounts to with the kit.

I don't know it for sure, but they are metric threads.
The four mounts in the corner are not for ceiling mount, they are for standing legs.

Interesting -- Don told me in a PM that he'd always used unistrut approach...I assume using what you are calling the standing legs. Any ever hang one of these by those holes? OR should I pay Don to mail us the correct mount that he simply forgot to give me when I picked up the PJs?
Incidentally, 3/8"-16 threaded rod fits into those holes well...ok, well enough I thought that was the correct thread. I wonder if a M10-1.25 thread is what it really is...the lead is about 0.012" off...
Well...looks like today will be the on-floor rough-setup and signal chain playing. I don't know NEC menus, etc. yet so this is all fine...just a bummer.

Use the proper holes. Not sure on the PG's but on the XG's we have seen chassis failures and dropped/partially dropped projectors

Ceiling-Mounting by the feet-holes caused a catastrophic failure on a PG10 years ago on AVS. The whole chassis broke and twisted apart.

Thanks guys -- I'll get Don to see if he can dig the mounts up and send them!
While it isn't on the ceiling, we did managed to get it psuedo-setup on the floor shooting onto a bedsheet. That is, we played just enough to learn our way around the machine and the menus. Don wasn't lying -- I can see where this will look freakin' awesome. I do loathe the convergence complexity compared to my super-simple ECP -- it is an impossible game of sorts -- trying to figure out how to get everything converged...too many choices! I also don't quite "get" the phase control yet and other facets. More to read and study.
Jon, and more importantly, his skeptic wife, was impressed already with a crappy image (BR of Planet Earth from the PS3 he bought and going into my HDF3)
Cheers,
Matt

Unistrut is fine, just use some right angle brackets:
The NEC convergence setup is the best ive ever seen. It is simple when you know what does what, and you can get it dead on perfect quite easily.

Definitely get the factory mount. Lots of threads on unistrut mounting in this forum and on AVSforum as well.

I'll be glad to ship it but I don't think you really need it.
Give me a call when you get a chance.

Finally, after 6months, my buddy and I both have a bit of time to hang Don's old machine AND we have the factory mount (via don at Cliff's). Before we get together next week, I need to get the 8 little bolts that hold the factory mount's two tabs to the chassis. Anyone know what metric thread these are? Case? By guesstimate, I'd guess the holes receive a M6 x 14mm long screw? (~1/4").
[The manual shows an M4 scew that locks the PJ angle at 11degrees, but doesn't specify the other screws]
thanks!
Matt
