Repair Summary

Not worth repair.

At full-throw of the pallet fork, the pallet stone does not clear the ratchet wheel tooth:

After mainspring replacement, the watch ticked through two or three teeth of the ratchet wheel, then get stuck. Normally, I would look into adjusting the ratchet wheel or pallet fork, but since the case was bent and the crystal shattered, I believe the entire movement was slightly warped throughout. When resassembling, the bridge holes didn’t quite line up, further indicating the whole movement is bent.

Job 3 – Plasma Cutter – Attempted

Customer brought in a plasma cutter that had popped when first powered on then did not power on after that.

I fixed the obviously-damaged arc drive lug, but the device still didn’t power on. It was not worth troubleshooting the rest of the device at the time as it is difficult to disassemble. No charge to the customer, but I probably should have checked the primary power section of the cutter first.

I didn’t take a picture of the final solder

The customer still has it. I may try troubleshooting again sometime …
