Hmm 😛
True they say the reflector will filter out IR, but what about all light that's not coming out of the reflector and instead heading straight to your lenses? Not trying to **** on your parade or anything, just curious if you've thought of it and what your plans where. It won't change any of your distances really and can be placed anywhere along the path.
Bleh, Sapporo beer in a can sucks, get it in a bottle if you can.

Greetings,
I got my Lamp and Ballast yesterday and desperate I was I could not wait to just see what I can get. That bulb is BRIGHT; I pretty much got blind when I stepped out of the room to grab something.
Anyways, this is what I did:
1. Drew the sketch I had on the 20x40 MDF and 12" distance between the bulb and the 330mm Fresnel.
2. Also put the respective frames in place and temporarily by putting nails half-way to hold them with some small support. I will post pics later.
3. Fired up the bulb, with about 3-4"+ distance as I don’t have the Tempered Glass yet.
Plan was to see if I can get the front 550mm Fresnel to get something to display where the triplet is to be placed.
I was able to see the picture clearly through the 550mm Fresnel when sitting straight through but as far as seeing something where the triplet is to be placed. No success: I think this is probably because there is too much light around as the enclosure is not closed.
So the plan is to put the sides of the box, so the box will look like a U shaped with lens and covering the bulb part half way to see if I get any success. Do you think this is going to work? OR Any other suggestions?

The key to your light problem during testing is you need to block the leakage going to the screen or wall. Doesn't really matter if it's shooting backwards or straight up. For just seeing an image during testing, the object you're projecting on should have minimal leakage going on to it.
When I was testing, I put tote covers all around my setup and put a heavy towel around the projection lens to seal out any leakage.
Good luck!

Thanks superdaveumo
So if I understand you correctly, then as long as I have the part from my 550mm Fresnel to my Triplet covered and sealed I can expect to see something at the focal point of the 550mm Fresnel?
Also, I am planning to use like a cardboard or a box between the 550mm Fresnel and the Triplet so hopefully I should be able to see something where the Triplet is to be placed.

I take it you are trying to focus the arc onto a sheet where the projection lens would be located (the focal point of the 550mm). Yes. If you have everything focused correctly, you should see the arc.
You'll want to block as much forward leakage as possible so you can get a clearer picture. Of course if you have mirrors on the walls or a shiny floor, the side and rear leakage could reflect forward and you'll have to block that too. 🙂
When you're focusing your lenses so you can see an arc, you should remove the LCD from the equation for now. That will make seeing the arc MUCH easier. Or, if you are not concerned about the arc and just want to see a picture, you'll want to use the LCD and put the projection lens into the whole equation and project it on to the screen or wall.
At this point for me, I literally mounted the bulb on a cardboard sheet, and had all the other pieces placed on top of stacked books and boxes. I then projected the image on to an off-white wall. I also had the tote covers laid over the whole thing with a towel around the lens.

Yeah I think I had too much light leakage from the 550mm Fresnel to the Triplet so I am going to do either one of the two:
1. Place the two side pieces OR
2. Cover the gap between the Fresnel to the Triplet with cardboard wrapped with a towel so I can see if I am able to see anything.
Will post details either later tonight after trial or tomorrow morning.

Some Results
Greetings,
Bad News:
While building a frame again for my LCD I some how damaged it and have a dead pixel line from top to bottm on the left of the LCD. However, LCD still works and don't seem to be an issue when watching a movie.
Good News:
I finally have my projector build to a point where I can do some testing and playing around. Although the cooling is not set yet completely I am determined to test it out.
Here are some images of the box put together:
Some Results:
Some More Info:
Triplet: 18" E. F (Lens Opeque Projector Lens)
Result Screen Size 1: 92 Inches - A bit blury focus.
Result Screen Size 2: 80 Inches - Very Little Blur on edeges.
Result Screen Size 3: 72 Inches - Looking good.
Pictures above are with 92 Inches full screen. So when watching movies I get a nice sharp image in the center. The projector overall still needs a lot of tweeking.
Also the LCD has Anti-Glare on both sides.
Also there is no display screen at the moment, just projected on the wall.
Any Suggestions/Coments?

Considering you are using a 18 inch opaque projector lens with a 19 inch lcd the results look good. As long as you are happy with the results then that's all that matters. When you do the tweaking of the projector don't forget to paint the interior flat black to control stray light. By looking at the pictures I'm guessing you used a LumenLab reflector with your light engine. What is it mounted on?
You are not gona believe what I used 😀
I took the Pro Reflector with me at Lowes and spent a few hours researching and browsing through different departments of the store.
The 'Sink Flange' fit just like it was made to hold the reflector.

Additional Tweeking Update
Greetings,
Finally I have my PJ tweaked a bit more and although I don't have any Video
Image pics yet I have some pics to share about the setup.
I will post some images as I get them, also I am awaiting on Pro-Lens from LL,
although I have the 18" Lens on sale.
Here are the Images:

Legs Where Too Long (From 15" to 10"):
I have to admit that the Image Quality of the colors is a HUGE difference.
I will share some pics as soon as I get the camera setup to take good pics.
Also when I hook up the Pro-Lens which is not going to be shipped till like
Sept 27 or so.
Suggestions/Comments always appreciated.
