American Pinball tech tutorial: tighten loose lock bars with screwdriver adjustment

American Pinball Tech Service releases instructional video on lock bar adjustment for their machines. Dave Brennan demonstrates the simple procedure of tightening loose lock bars using a flat blade screwdriver on two brass screws, with assistance from Jacob. The technique involves equal turns on both screws, trial-and-error based on foam thickness, and checking tightness by hand pressure. The adjustment method has been standard since the 1970s across multiple manufacturers.
