Hi, With the prospect of ceiling mounting a Barco 701s, and having a screen-drop of 19 inches, I'm concerned that if I mount the Barco level with the height of the screen I'll have a CRT lens shaped dent in my forehead before long..... I'm very reluctant to sacrifice my current screen position, but if I mount the pj near flush with the ceiling I'll have 3 or 4 degrees of tilt (on top of the 10.5 built into the projector)... I could reduce this to 2 and still have the projector out of harms way, subject to some more fun and games with the lens program and a measuring tape. All the stuff I've read about super setups lay great stress on having the projector level - and I understand why. Having seen pictures of james installing Phil Hinton's projector levelling it with a spirit level, as well as reading loads of other stuff, I am obviously anxious not to create focus problems for myself, which I understand is the greatest risk. I have waited a long time to dip my toe into CRT water and I want to get it right. My question is whether I can shim the lenses to compensate for any additional tilt - I've seen Roland refer briefly to this in the dim distant past, but have come across nothing despite fairly intensive reading on the net (this is, no doubt tempting fate - someone somewhere may have a link to a site explaining this in detail.... or maybe not.) If shimming is a viable proposition, where do I get the shims, or do I have to make them, and is there a means of calculating the "degree" of shimming required. I intend to do a "coffee table" mount during a trial period, so will have the chance to experiment with the degree of tilt and see whether I can come up with an aceptable compromise - I intend to construct a base which will allow me to alter the height of the table and tilt the top to mimic different positions before finalising a ceiling mount plan, to see how it goes. If shimming is excessively complex (or requires the experience gained from professional installing), I'd like to know up-front. If there is a significant material downside to the approach, that would also help. On a side note, could someone tell me what the substantive diference is between a 701, 708 and Cine7 ?? Thanks in advance, Sean.
