I just wanted to relay a hint that I've found pretty useful on a couple occasions, and that is that stick on rulers can be very handy, particularly ones with a millimeter scale. Years ago I used one of these on the spinclination type Ajax mount, since mine didn't come with any scale on it. You can also wrap one around your pipe, as an indication of azimuth for a Az/El mount.
Yesterday, I moved my Primestar dish, and I set the polarization skew of the lnbf crudely by just watching the signal on my computer as I turned the lnbf, but today, I decided to check it out. The skew was supposed to be about 39.9 deg, but there aren't any markings on my mount, so I wrapped one of those stick on rulers all the way around my QPH-031, with zero at it's zero position. It was 147 mm circumference. I then checked on the ruler where the vertical mark was on the lnbf holder.... it was at 17. Did the calculation, 17/147*360=41.6 . This is pretty close to the 39.9 I was supposed to have, which surprised me. Basically right on.
Anyway, there are lots of places on TVRO setups that could benefit by having a fairly precise scale, if for no other reason than to allow you to reproduce setting when you start changing things. Only problem with the stick on rulers is that they don't stand up to sunlight and rain, etc. But they are cheap enough that if they come off, you can put a new one back on.
