Pins are meant to be put in bars and have the unwashed masses pump money in and play them. They are made of tougher stuff than most people think. If your on laminate floor you really should use rubber feet to make sure they don’t slide out and damage the floor or bump into walls and other machines. Pinball resource is an excellent source for these (one of the cheaper suppliers)
These are not items to be kept in their packages and wiped down with diapers IMHO they are meant to be played. If your concerned about excessive nudging tighten the tilt bob. If your worried a few slaps and shoves will damage your work of art you probably shouldn’t play them at all with the risk dimpling your playfield each time you airball a shot. However that being said it’s your game do what you want with it but for me as long as you keep 4 legs on the floor I say play on player. I have never damaged any of my games with slap saves and pushes and I regularly host tournaments with over 50 players at my garage. All of my games have the tilt set so that the player can get one good save with a warning or two but excessive nudges will tilt. Nudging is always been a part of pinball even in the era when they sell for over 10k.
