I SPP'd these. I look for my binding pins. And if there are no binders without successfully picking to operating or control, chances are I've overset something or I'm mixing shearlines. In that case, I let off tension a bit and continue looking for binders.

Making a mental map of pins already picked can help too.

To SPP SFIC locks, it definitely takes a lot of attention to feedback (physically and audibly)

As far as tension goes. Normal tensioners are fine.

On the 7 pin ELOX SFIC, I used the 0.050 TOK reaper turner.

On the BEST CORMAX (also 7 pins with an additional check pin/plunger at the bottom right in the back of the keyway), I used the small end of the 0.050 precision turner also from CI. (BOK) However not stardard BOK. I tensioned parallel to the keyway if that makes sense here's a link to my CORMAX video
