machine : Nugent .... symptoms of patient : lifeless pops
quick inspections reveal 2 rings with only one threaded nut remaining so a complete rebuild is needed, while disassembling pops noticed the most lifeless pop & only one with two nuts on the ring had no coil sleeve in the coil - duh
solution : replace all three pop bumper rings, coil sleeves, clean spoons & adjust switches
result : amazing pop bumper action
machine : class of 1812 .... symptoms of patient : many playfield posts are leaning at very strange abnormal angles - wtf?
quick inspections reveal someone used a non-hardening painters caulk to try and fill in over sized holes on the playfield and stuck the posts back into the gooey mess which did not work out so good
solution : scrape out all caulk, clean holes as good as possible, trim wooden dowels down to fit over sized existing holes & glue into place
result : vertical posts are solid & look great
