Just an update....I got "Sky Jump" back together and working/scoring properly. The 7 drop targets were good practice. I created some additional issues for myself, but that is also part of the learning process. Cleaned some switches and replaced the coil sleeves, as well.
I also replaced one drop target I broke on "Amazing Spiderman" the very next day. It was much simpler as the bracket was modified by the factory by this time, so replacement was a snap thru the slots on the lower part..
I was empowered to give my "Target Alpha" a go as well.....2 banks of drops for a total of 15 targets!! I replaced the five on the smaller bank first, and it went off without a hitch. I am now eyeing the large bank of 10 and getting my courage up!!
