Hi folks.
Following another recent post of mine, I've managed to mostly dismantle my new-to-me Mir-47K. I've removed all of the front element groups, and the rearmost group, but the next one at the rear will only pull up a couple of millimetres before it sticks. I'm using a suction tool with a fair amount of suction, but it's not moving any further, though it's clearly not physically attached - it just jams on its way out of the inner barrel.
Can anyone advise on how I might remove this rear group? I'm thinking that heating the barrel with a hair dryer might work by expanding the metal ever so slightly. Is that a good idea, or are there better ways?
Any help would be greatly appreciated. Thanks in advance
