Copal shutter speed dial tension adjustment

I recently had to figure out how to adjust the tension on the shutter speed dial for one of my large format lenses. There are lots of good written guides, but few videos, so I thought I'd document the process.

Thank you! I had no idea there was a tensioning ring on the Copal shutters. Fortunately, my shutter speeds are already easy to adjust.

I watched this and I have zero need for this information. Thanks. lol

Just scored a few Fujinons with Copal0 0's so this is good info, thanks! Do you have any idea about similar adjustments to the aperture selection lever? My 90/8 is quite loose feeling, while my 150/5.6 requires a fair bit more effort. Blades are minty and clean on both, just the lever resistance varies between them.

I honestly have no idea, sorry. That same 105 has an annoyingly lose aperture lever. I'm tempted to just take it off and put a shim under it to add friction but that's not ideal.
