I applaud Charlie and co for starting a pinball company and for releasing some really fun games. I'm not going to defend jerk customers, but in an established industry like pinball, learning and utilizing best practices leads to far fewer situations like this playfield episode. I love my TNA but I do question some of the odd decisions that were made that could have been avoided simply by watching what others do....some examples:
1) Why are the lockbar and rails so sharp? Aren't battle-tested lockbars and rails available off the counter? And if you want to make them yourself, can't you follow the example of every other manufacturer, and make sure they are deburred?
2) Stern's displays have always sat an angle with the top further back, to reduce glare and improve color display contrast. But TNA's display faces head on, and when combined with a low-budget screen, produces poor contrast and color. Tilting the screen even 5 degrees back using washers greatly reduces this issue. Something Spooky still isn't doing at the factory for some reason.
3) The playfields are not given time to cure properly, which results in both chipping and scratch marks all over the place on NIB machines from them wiping them down at the factory - which you cannot do if the playfield hasn't cured yet. The reason Charlie hasn't "released" the reason why all those playfields are chipping is because the reason is quite simple: they didn't cure properly.
I get it, Charlie. Pinball is hard. But it doesn't have to be quite as hard if you take cues from established players.
