Great job on this. Can see how it would be hard to find the problem as it looked ok. Thanks for sharing. 👍👍. Bob

It's a tricky one

[@davidh6713]

Timing and masking circuits are tough to understand , and sometimes tougher to teach. Thank you for sharing your skills.

[@goatshedempinballrepair8545]

Yes they are tough for sure.

Hi guys, another great informative video. I'm have the slippage problem with the set screws on the roto unit shaft om my Hi Dolly. I wonder why Gottlieb didn't case harden the screw location area and then grind flats so the screws could make contact on a larger area. What is your view of using a product like Loctite might that help solve the problem do you think?

[@goatshedempinballrepair8545]

Take the unit apart and remove the escapement wheel and file the are where the screws go. Locktite may make it difficult for future repairs.
