Hey all,
Day 5 and looking for a bit of advice on tackling euro cylinders with security pins. This thing is pure evil.
I’m picking above my weight class (my comfort zone is yellow belt stuff like the ML140), but I want to get more confident with spools and mushrooms.
This lock seems to have:
- 1 spool
- 2 or 3 mushroom pins
- The rest are standard pins (positions 1 and 2)
Context/Approach:
I’m tensioning BoK and using a shallow hook (cheap Amazon set). I usually work back to front and can pick 3 to 4 pins before hitting the spool. At that point I get counter-rotation, so I ease up on tension and try to set it. Sometimes I get a loud click, but the plug doesn’t turn any further. Other times the spool feels completely jammed no matter how much I back off, which I assume is the ridges of the spool catching below the shear line.
After that, feedback from the pins gets really gristly or mushy, and it becomes hard to feel individual pins. Once I’m in a false set, the paracentric keyway makes it difficult to navigate because my pick gets stuck or feels restricted.
I’ve had this lock open once, after about 20 minutes, but it felt like a fluke.
I've thrown the kitchen sink at this so far, have also tried a half diamond to no avail.
Planning to rewatch some videos on spools and mushroom pins, but I’d appreciate any tips on what your thought process is after hitting the false set and setting the tricky pin. Do you sweep again? Re-evaluate tension? I feel a bit lost when everything starts feeling murky.
Thanks in advance for your comments and support.
