Here is my newest version. I'm so glad the aluminum box arrived today! Took 3 weeks since it came from HK  I've tested it too and it works. I love the new look!

Ok, folks. I need help regarding mechanical convergence. I read the manual and it mentions about washers. I removed the lenses but I didn't see any washers. Please see attached pictures of what I saw. I noticed there were long vertical screws that can be rotated. I'm also thinking that the part where the lenses are mounted to can be moved by loosening the screws on top. However, nothing about these longs screws were mentioned in the pdf manual. How should I proceed with my mechanical convergence?
Oh, I'm optimizing it for 3.2m screen width and up.
Thanks!

Ok. What I was trying to do is adjust the lenses since I put the barco 13ft from screen. On my Sony 1272, I put spring on outer lenses which allowed me to twist the screw as it tightens and lens moves slowly from left to right/vice versa.
So with our Barco and reading the link you sent, we don't have to remove the lens to do the mechanical aim? Looks like it's the tube that needs to be moved.

The toe-in is adjusted after the bolts are loose on the top panel.
there must be a set-up guide here somewhere, or - try the guided
setup in the menu...

I'm sorry but which part is the toe-in? I'm assuming it's the gray plastic square?

I displayed a pattern so I can see what parts of the raster is being used. It looks like the previous owner set it up properly.
I think I should mention this: when I was converging red to green electronically, I reached the max and it red crosshair was still far from green crosshair. This is the reason I want to mechanically adjust the lens similar to what I did with my Sony 1272. Also, the steps that I was doing for my 1272 could be making me confuse.
Sony steps
1. reset counters all to factory
2. display cross hair in the middle(assuming projector is centered to the screen)
3. adjust the screws on blue lens so blue crosshair is very close to green crosshair
4. adjust the screws on red lens so red crosshair is very close to green crosshair
5. adjust red electronically so it converges green
6. adjust blue electronically so it converges green
7. etc, save
I was thinking that Barco might be different. In my 1272, I didn't move the tubes.

Finally, I figured it out. It's the red and blue tubes that we need to swing. I returned the lenses so I can start converging. However, I would like to reset everything back to factory default before I manually aim it. Where is it in the menu?

You need to re-install the top piece above the tubes to actually fix the red and blue tubes to the proper "toe in" position...

Thanks everyone for all the help!!! It's watchable now. The only thing I need to do is remove the existing crt projector, then install the Barco.

The Barco convergence you can just center everything out because it gives you the adjustment ranges. I don't even remember if there is the equivalent of a factory reset on an 808? It's been a while.
But you need to physically swing the tubes as I think you've figured out.
Then you use the long screws poking out the front for lens flapping during optical focus (NOT centering the guns for the particular throw distance).
All of this is covered pretty well in the G808 install manual:
http://www.curtpalme.com/Barco808_Downloads.shtm
Look particularly starting on page 59 and on from there. You should read the whole thing though.

Ok, I will search the pdf on how to delete the memory blocks. Thanks.

I redid the focusing and convergence using binoculars. Movie is Toy Story 3 played on Bluray at 1080p. So far, I'm very pleased with the results. Maybe it's time for me to work on my home theater

Material is blackout cloth that I bought from Jo-annes fabric. They only sell 54" in width. You can see the thin black seam line in the middle because I stitched them to be able to get a height of 67-70". It's currently at 126"x70". However, since the projector is on the floor, it's also being projected on the lower part.
Here is a 2007 image but size is different now but still the same location. Sorry, basement is very messy. Sony 1272 seen on pic, ceiling. It's still mounted.

Can someone please post a close up picture of how you made the mount on your Barco projector? When I acquired my Sony 1272, it had the mounting kit included. However my barco only includes 2 piece of metal that are screwed to the chassis. I'm also thinking that the screw isn't strong enough.
Any help would be greatly appreciated. Thanks.
