Rusty Strings Posted March 2, 2013 Share Posted March 2, 2013 Not so much a problem with the laser as the 2" adaptor. The 3 rubber rings seem to have expanded and don't allow the adaptor to be inserted the focuser without dragging. Can they be replaced? Link to comment Share on other sites More sharing options...
red dwalf Posted March 3, 2013 Share Posted March 3, 2013 funny you should say that John, a newbie, Allan the plumber had the opposite problem, when tightening the 2" adapter the rings wouldn`t expand the rubber washers, FLO replaced then adapter for him free of charge. don`t know if you bought it from them or not.

Guest Eddy Posted March 3, 2013 Share Posted March 3, 2013 I don't own one but imagine they are just o rings? Probably wrong though, Link to comment Share on other sites More sharing options...
BAZ Posted March 3, 2013 Share Posted March 3, 2013 If they are O rings, then could someone let me have the Hotech, I'll measure it, and the O ring cross section. There is a company near me that I get bearings and seals from, Iam sure they would be able to help. It sounds like the O ring is degrading, and beginning to expand, causing the trapping problem.

red dwalf Posted March 3, 2013 Share Posted March 3, 2013 they are like rubber o rings, but they have flat or square faces to them instead of being round like normal o rings if that makes sense Link to comment Share on other sites More sharing options...
BAZ Posted March 3, 2013 Share Posted March 3, 2013 Are they square then, or do they have a flat face n one side, but round for the rest of the section? Link to comment Share on other sites More sharing options...
red dwalf Posted March 3, 2013 Share Posted March 3, 2013 the one i looked at recently had flat faces to all sides, Link to comment Share on other sites More sharing options...
Rusty Strings Posted March 3, 2013 Author Share Posted March 3, 2013 They are rectangular in cross section. With the tightening ring loose, the rubber bits are loose on the adapter tube Link to comment Share on other sites More sharing options...
