chris_eve Posted October 25, 2004 Share Posted October 25, 2004 I've just aquired an LTM Orion 15 (cheaply) which is fine in every way except for an intermittent sticking of the focus thread. My guess is there's a small bit of grit or similar in there which needs removing. I can usually figure out how to strip and rebuild a basic lens without too much trouble, but this one's got me stuck. There's three grub screws on the periphery of the front of the lens, which I've removed, but nothing want's to move/unscrew after that. I'm guessing the thread is stuck/frozen (the lens body is aluminium) ... what I need to be sure of, before forcing something the wrong way, is whether or not the focus ring should now unscrew from the body, and if so clockwise or CCW (left or right-hand thread) ... or if not, what else needs to come off.

peter_4711 Posted October 25, 2004 Share Posted October 25, 2004 Hello Chris, I have an Orion-15 too, but your Orion have a KIEV or LTM mount ?Beware of strip-down more to the lens block, a ORION is very difficult lens system, and very easy to destroyed. peter Link to comment Share on other sites More sharing options...
