Lindberg dismantling and mounting lenses

[HonziH]

Hello,
customer brought to us Lindberg frame for repair and I have no clue how to dismantle this frame without damaging the lenses (I already chipped away one of the lenses by brute forcing it) and then put them back together. I've worked with Lindberg frames before, but have never seen this type before. It's model 5302, I can't even find what line of frames it is. They probably discontinued this line, because it was stupid design (yeah, I don't like Lindberg). Anyone willing to help me?
Cheers,
John

Edit: Never mind, I figured it out. It's stupid and my thumb nail is destroyed.

If I were trying to make lenses for that frame, I would use Trivex (which may not be available or widely used in the Czech Republic). I would take it down until just slightly large and then take mini-cut after mini-cut until I could snap it in. At some point it'll snap together.

But you're trying to fix the frame and using the customer's own frame. I would wrap my hand tightly around the frame with the lens in place and try to persuade the parts to snap together.

I feel your pain.
