> Steve, what is "my Orion mast-clamp"?
I offer an after market mast clamp for the Orion. It's hot-dipped
galvanized and uses 6 U-bolts to hold the mast. It's $160. It's not currently
on
the website but I can send you a photo of it if you'd like.
> What are the fatal and semi problems?
The fatal problems with the mast clamp are 1) the dimpled surface that
over time allows the nuts to loosen up and 2) the misaligned and irregular
teeth on the clamp that are supposed to hold the mast. For such a massive
clamp,
you actually wind up with a miniscule amount of surface area that actually
holds the mast. My experience has been that virtually 100% of Orion clamps
loosen up over time.
The semi-fatal problem is the IMO terrible controller (that only the
design engineer could love) and the equally terrible documentation. It always
takes one or two calls to the factory to get one working properly.
> You are saying not to use the mast clamp that comes with the 2800 factory?
Yep. There was a discussion of the problems on Kurt, K7NV's' website but
I couldn't find it. Maybe someone else has a url for it.
