I spent too little on my Star Trek TNG table which led a rough life on location and is approaching 100,000 plays. I've ended up spending more than I care to admit on parts getting it to a playable state.
At first, my goal was to get the table to play well (rebuilding the flippers and replacing boards.) Then, my goal was to make it less buggy (Redoing inconsistent optos, replacing corroded leaf switches.) Then my goal was to fix serious cosmetic issues (plastic chipped on Delta quadrant ramp, replace heat warped parts.)
Now, I'm so far in, I'm considering things like replacing all corroded surface screws, redoing the shield inserts, and getting new ramps. My husband thinks this is too much because he doesn't perceive these things. But, he isn't the one who's taken the table apart 20 times.
My question for all of you is, when are you "done" restoring a table?
