Problem with a microscope

#1 Post by ivangallego24 » Tue Jan 01, 2019 8:01 pm

I have a problem with this equipment in particular is a euromex iscope I do not unscrewed the objectives of the revolver only the casing comes out but the objective remains as very hard screwed, it has five objectives and a while ago I bought one of 20x and I screwed it in the one that was left but there is the problem that I want to put them all in an order and if I do not unscrewed the other objectives that came with the microscope I do not know how I'm going to do it.

Try winding a rubber band around the objective, it will increase the grip.
Zeiss Standard WL (somewhat fashion challenged) & Wild M8
Olympus E-P2 (Micro Four Thirds Camera)

Wrap a narrow leather strap around objective base; the knurled part. Then put the large part of the jaw of a pair of 6"(150mm) or 8" (200 mm) slip joint pliers gripping the leather strap. It would be best to set the pliers to the large setting in the slip joint. You can easily just loosen the objective that way, then finish with your fingers. Small 6" vice grips can be used as well.

If I understand the problem correctly, Ivan, you will need to grip the the knurled ring [nearest to the screw thread] quite firmly ... without bruising it !!

I prefer to use the rubber sheeting, called TheraBand, which physiotherapists prescribe for exercises ... but other materials are also effective.

But does anyone know why they come so hard from the factory?

Sorry, No

I had assumed that it was an old 'scope that had seen some heavy-handed use
[ or was deliberately tight, to stop anyone 'borrowing' the objectives ]
But if it's 'factory fresh' there is really no excuse.

Thank you very much for your help but I already managed to remove the objectives, it was just that they were quite hard
