The counterweight shaft and counterweights and the dovetail and tube rings are all steel. These are where the levels are used anyhow. I also used it on the pier itself since it has no level. Fits right across the top and can be put in any direction.
it just makes it easier to level the pier before adding the head. Of course I use the level in the Park 1 and Park 2 positions. With three counterweights it is longer then needed. I ended up putting it on the three countwrweights themselves. Fortunately, they are all the same size.

A 5" level would be even better than a 7" one. The 7" level was more accurate than a picture hanging spirit level. I know because I tried both and found differences.

Oh, just bought a cool bubble level with magnets on the base a push button on/off light switch that illuminates in green.
That ought to make dusk alignment a whole lit easier. Venus will be the one to slew to for initial alignment.

The bubble level sounds pretty interesting but I'm not so sure that the magnets are going to have much to grab on to. The mount is aluminum, brass, and stainless, none of which are particularly magnetic. ;-)
