Well, the deed is done. The ECP is now ceiling mounted after a lot of tedious work from sourcing materials, cutting, drilling holes and finally hoisting into place. After cutting a single gash in the ceiling with a saw I found the exact location with two chicken/turkey skewers pushed up through the drywall to help find the joist. Nothing in this basement apartment is plumb or square. I measured from the wall to a joist in the bathroom behind water shut off valve hatch. One would think that same measurement would reflect off the living room wall, nope.. off by more than 1".

I tried to cut the washers at a hardware store with tin snips like suggested, no luck as they were too thick ~1/16" or slightly thicker. A vice and hack saw worked perfectly and they now fit the channel exactly, with probably about 1/32" movement.

I may get shorter eye bolts to raise the projector about another inch higher as they bottom out in the ceiling now.

With a bit of 500 and 1000lb test clothes line kicking around, complicated trickery of hoisting each corner a few inches at a time and a bit of muscle everything went in place perfect. I tied up the back corner later on which made it al that much easier. I'm extremely pleased how it turned out. Tomorrow after work I may start the alignment and bolt it in place.

I built a custom pj bracket for my set with a pivoting pulley section. Had to go this way due to joist orientation. It's extremely strong and worked like a charm.

The ceiling mount is unistrut based, exceptionally heavy duty, full range of needed adjustment range, and tucked in fairly tight. The pulley section in the ceiling is a bit hill-billy, but still very strong, supported by (4) 6" lag bolts in sheer screwed into a large structural beam. I reinforced the supporting OSB i-beam joists by sandwiching them with 4'X8"X.75" 5-ply plywood. Supporting bolts go through reinforced joists with purchase spread over large square washers. Heavy duty brackets connect to strut. All bolts are captive. Cosmetic skirt to go up soon that will cover hole and all hardware.

I love the DIY pulley lift! Nice work!

Pulley mounts rock! Nice work!!!

I must say, that pulley system is impressively complex yet brilliant! I assume it made for hoisting a breeze for the most part? If the projector is to come down or a new one installed in place of I'll definitely have some type of pulley rigged in there next time as doing this alone was tedious.

I followed a method Clarence mentioned. I used threaded rods on the pj witn eye loops on the attic side, with rods passedthough dw holes cut on template centers w a 2" hole saw. - and attached to roof joists with chains

Not heartily recommending as it was difficult to hoist up one corner at a time and I needed a little twist to get it spot on once mounted.

But there is no way to get it higher than such a flush mount. or more cheaply. And thepj has nevercome down in the three years since mounting partly because to do so would be a PITA

I noticed all of these Uni-strut-based mounting solutions are 1-axis. I take it its a matter of raster-shift vs raster size that is most important in deciding which of the two 1-axis solutions is implemented. For instance, a 1-axis solution that allows forward/backward movement will offer zero benefit for the shifting of the raster, but will for the size of the raster. Converse;y, the side-to-side 1-axis solution provides for raster shifting, but not raster sizing support.

I love Elaine's approach to the solution and it seems to work for the application. While the forward-backward movement can be locked, the bars running side-to-side can still be used. I might have to employ this method in my basement.

What type/size screws would you need to mount a Nec with Elaine's system and which screw holes can you use?

Thanks.
