You wouldn't happen to have the set suspended do you?

If yes does it move?

I am toying with the idea of getting two marquee split pack chassis for my blend setup

All I can tell you is this - chains are not equal in size as one would imagine. Of the 4 chains that I bought, 3 were more or less equal in size, but the 4th one was a whole link longer than the rest of them, forced me to make a "thingy" that would counter act the pj being way off now. I used a laser for all of this and yet the outcome was very disappointing, the image was off by at least a foot to the left. So chain are no good at all I'm afraid.

It took 5 minutes for it stop. Gave it a little nudge, but It's still moving after 5 minutes, but just barley, so 5 minutes is the rate for me at least. Chains are good if you incorporate length adjusters that are found on boats that are tied to the docks for an example. I'll post an image showing how they look. Using them chains are perfect to the tee.

And yes, the chains in the roof need to be separated by at least a foot wider than that of the pj. Doing this should make it solid in place indeed.

Noted not sure yet how I will mount the sets but ceiling mounted sounds best as having two of these beasts setting in the floor is a tad but of a space hog

And one more thing, don't be tempted to make it absolutely in a 90 degree angled towards the screen, it doesn't have to be, but rather a foot or so higher and slid a comfy recliner underneath instead, or slightly ahead. To be the King of your domain sort of. Smile

I am brave but not that brave to have a 200 pound beast above me Smile

Maybe if I had a split pack chassis

Nah, these bolts will hold on for way more than that, especially if the bolts a further apart than that of the pj. You could even make more bolts to the ceiling as well - if that would re-leave your mind a bit. Either way, I'm looking forward to see your final set up as I also wanted a stack on my own. Imagen, cutting contrast and brightness in half, and then double the light output to top it off. It would be sharp, I gather, with only half the contrast and brightness.

Oh ok

I may or may not do a stack depending on how the blend goes(if i find it too tricky for me then I will do the stack)

How big are your room to even think about blend? It has got to enormous to even go that rout. I would think.

BTW, The bat-cave that I'm looking forward to, would be Jarmo's and his Frankenyokes + LUGs marquee with MY lenses! Now that I would pay to see. I'll row over there just to see.. Smile

I have plenty of room its a matter of the equpment needed to do the blend

I plan on getting some frankenyokes to put in my marquee soon

I am getting some lens for 9 inch tubes soon so its going to be fun

Now to find a couple split pack marquee chassis Smile to transplant my stuff over

The drifting problem has been solved! What took over an hour before, to make red settle in over green is now down to only 6 minutes, and after about 10 minutes it's about done in all areas. I had forgotten to tighten down red and blue gun, as they were only semi tight, that's my way of setting things up over some days. I only use enough pressure to allow me to smack the lenses and do toe-in that way. A little by little each night, over say a week. But, since I never really got it right I gave up on it and forgot to tightening them down again. One other thing I noticed for the very first time, when I fiddle with the magnets for an example, and then walk up to screen, red and blue go in and our of convergence with the pj just swinging a few mm! I never seen this before during this whole time until tonight. If the lenses and top plate are not bolted down very hard the chains allows the chassis to flex, and just maybe, enough to make the lenses off a bit after some time. No-wonder why I never seem be done with this. It's been 30 minutes now and convergence is still in place as I'm typing this, so all is good. Thanks again for all the input you all, and good luck to you to big E with your build there. Looking forward to see the end results also.

Awesome glad to help out

I have this issue with my dwin(leaving the bolts loose due to a issue in the set that I am getting fixed soon)) if I bump the set it will throw the alignment out of whack slightly

I will be posting a thread soon for a couple marquee split pack chassis to do my project(split pack chassis take up less cealing space and headroom that can be used for seating)

Also I am working on a tv that was gave to me for free(almost got it fixed) I will be putting new tubes in it once its fixed(it uses the Panasonic p16 tubes)

BTW, I retubed a MArquee 8110 that I'd sold a local university about 5 years ago. They put 22,000 hours on the set, and grass was pink. Smile

Tube emission was still OK, but what I marveled at was how tight the convergence still was. I'd never gone back to tweak it, as they only call when the thing dies completely.

I am going to guess the tubes looked like the ones in my samsung tv?

That's a lot of hours on one set of tubes(wonder when they started to notice the link grass:))

Btw curt when I did get the tv to show a pic it did have a red/pink hue to the pic before something in the set triggered the failsafe

I think I may need my convrgrence board in my marquee checked at some point as it does tend to drift at times during use(haven't messed with anything on the set latey(will email soon)

I like to revise my numbers that takes the pj to converge - it's now 23 minutes. Late this morning, after re-aligning toe-in and some work on central-magnet-ring I turned it off, opened up the balcony door, to allow it to cool down faster, and went to bed for like 30-40 minutes. Got back up and timed it to 6 and 10 minutes.. Went back to bed and tried again just now, I started @ 17:43 and didn't think it was aligned until 18:06. So clearly it wasn't all the way cool down before, but still more than a 50 % reduction. Those numbers are bound to change even more times as In the middle of my beauty sleep, the courier rang the door with my blue tube today, and it seems it made through customs without adding VAT. I was expecting it to arrive @ the post office first with a note to bail it out.
