I consider myself still new to the world of pinball. I know so much more than when I started three(ish) years ago and I want to pass on something I hope will help a new pinsider/hobbyist. This is the part where you raise your hand and promise (doing your best Arnold Schwarzenegger impersonation from Terminator 2) "I swear I will not kill any pin." What I mean by this ill-fated attempt at humor is before you do a repair, tear-down, or even wax please do some research.
When I started out I had no clue about anything other than the fact that I truly enjoy pinball. I realized this when I started to "shop" my first machine. I must admit my version of shop was to unscrew everything above the playfield and try to wipe it down with a microfiber cloth and change any bulbs. Take pictures, sort items... blaaa that is what my good...no great memory is for. This method lasted all about two days when I suddenly realized I had no idea what bolts, washers and screws went together let alone where items and posts went on the now very empty playfield.
Now after being on Pinside and seeing bad repair jobs that cause more problems than they were generally intended to fix I am more cautious. I read and check and slowly enter the deep end of trouble shooting and restoration. Now if you have years of electrical work or are an expert in painting by all means laugh at me. But if you are an everyday Joe (with just enough information to be dangerous) that loves pinball and wants to contribute to the hobby by preserving and restoring some of these gems... well... sit down welcome to Pinside and happy reading!!!
