I recently (a few hours ago) acquired a hardly used Vixen Porta Mount II (Standard). The alt-az adjustments are sticking about as tough as one of my 50+ year old Royal Astro GEMs - before I restored it. Its like its "lubricated" with epoxy that's designed to only partially set, you know, like pine tar!!.
I have scoured CN and only found one reference to the same problem. One of the responders said they had to contact Vixen for help (I think they said that - I can't find the post again!). Anyway, does anyone know of how to disassemble those components and what I should be watching out for? I recall that one post mentioned said it wasn't as straightforward as it looked and some parts got strewn about during disassembly (thus, the call to Vixen). For all I know, its those two small set(?) screws or friction adjustment(??) screws that are just too tight. Before I just loosen them, I'd like to know is stuff will just come shooting out once they are loosened... (That's how I lost that little ball bearing and spring in my pressure washer - haven't been able to suck up soap since! lol.)
I found a copy of the manual online but it isn't a "service manual". I have taken apart some really complex things before but learned to heed warning from those that have been there before. (I admit it did take me a while to learn that.)
Any hints are welcomed!!
All the best!
