content: HiI'm trying to remove the handle from an Hameg scope (HM203-6) but the nut spins freely, or better it spins with the small bolt coming from the handle, so the two do not unscrew ...I tried turning both clockwise and counter-clockwise but it doesn't seem to make any difference.I tried pulling/pushing the handle out and in since it locks in some positions thinking there is maybe some magic combination where the bolt can be locked in place but it doesn't seem so.I have a sinking feeling I'm just being seriously dumb.

content: You just have to bite the bullet, & hold both the bolt & the nut, like any normal such setup.A thin "set spanner" ( fixed wrench) would be best, as an adjustable one will probably have trouble with such a thin nut.

content: The fixed wrench is not a problem, I have it, but are you telling me I should keep the bolt fixed in position in some way while I'm turning the nut ?But the bolt it's just 1 mm above the nut... not easy to grab and hold it.I find hard to believe that's the way the dismantling of this thing was intended... are you sure ?

content: Maybe try cutting a slit in the bolt using a Dremel tool and a thin cutting wheel so you can use a flat screwdriver then to hold the bolt?Or cut through the nut and bolt alltogether if not concerned about preservability of the assembly,

content: Removing it at any cost (by cutting the nut in half or making an incision in the bolt) would not be a problem , but I would like to preserve it as it is.I'm just wondering if there is an intended proper way to do it or if Hameg bolted the handle never considering someone may want to remove it.What I'm asking is if someone has removed one of these handles "properly" and howBut thanks for the suggestions

content: I have removed the handles from my Hameg scopes some 25 years ago and cannot remember the details, but I'm 100% sure that I didn't need to cut slots and/or destroy anything.Maybe try to remove the plastic covers on the handle to gain access to the bolts?

content: GeniusYou need to put a screwdriver in the holes and push outward to release 4 plastic clamps, while wiggling the cover.Then you need two fixed wrenches, 8 mm for the internal nut and 10 mm for the external one, then rotate the internal one anticlockwise while keeping the external one locked.Images for future references ...EDIT: one of my other Hameg has a different cover, this one opens differently, pictures added.
