I have a couple.
My bulb removal / insertion tool is made from shooter plunger tips. Small screws hold them to the plastic rod. The short end is for installing, and the long end is for removing. It will pull 555s from anything with a quick tug.
This one is for tightening / removing the sleeves that the playfield sits on in games like TAF. It's a backbox bolt, cut off, with a roll pin in it.
