Deep technical dive into EM score reel design variations across manufacturers.
Gottlieb was the first manufacturer to market with a score reel game, and other companies played catch-up with different designs rather than copying Alvin G.'s approach
high confidence · Nicholas Backbone, episode 83 intro segment
Alvin G.'s decagon score reels used internal horizontal switch stacks mounted underneath the rotating reel, requiring complete disassembly to access and adjust switches
high confidence · Nicholas Backbone, detailed technical explanation of decagon construction
Metal decagon score reels (early Alvin G.) have not held up as well to time and neglect as plastic ones due to pitting and corrosion that adheres crud
medium confidence · Nicholas Backbone, personal experience-based assessment with caveat that others may disagree
Once properly serviced and adjusted, Alvin G. score reels require the least adjustment of any manufacturer's reels
medium confidence · Nicholas Backbone, personal observation from hands-on experience
Midway motorized score reels from the 1960s used clutch mechanisms similar to bingo machines and could spin faster than solenoid-driven reels without requiring a separate score motor
high confidence · Nicholas Backbone, technical description of Midway system
Midway motorized score reels attach to the motor via nylon couplings that are over 50 years old and prone to snapping under pressure from heavy metal parts
high confidence · Nicholas Backbone, discussing durability and replacement challenges
Replacement nylon couplings for Midway motorized score reels are currently unavailable commercially; 3D printing may offer future solutions
high confidence · Nicholas Backbone, discussing repair logistics
“Alvin G., aside from the plastic score reels that they used towards the end of the EM life cycle, in earlier times they used metal score reels and these metal score reels honestly I've found have not held up as well to the rigors of time and neglect as the plastic score reels”
Nicholas Backbone @ ~6:00 — Directly challenges conventional wisdom about metal vs plastic durability in vintage pinball
“The dreaded word for Alvin G. score reels is decagon”
Nicholas Backbone @ ~7:30 — Establishes the cultural/technical reputation of this design variant within the technician community
“While it is a pain and a half to have to disassemble these score reels in order to clean them or to correct their operation, once they are corrected, I will say that Alvin G. score reels require the least adjustment out of any of the manufacturers”
Nicholas Backbone @ ~16:00 — Core technical thesis: service burden vs long-term stability trade-off
“Alvin G.'s extra touch of quality extended to these score reels as well, they're mounted on these nice brass plates which can be removed and it's just a very attractive unit when you have it in hand compared to the plastic and metal nightmares which are clipped in they're made by every other manufacturer”
Nicholas Backbone @ ~18:30 — Illustrates design philosophy differences: Gottlieb prioritized craftsmanship/presentation over service accessibility
“The biggest thing to remember about the motorized score reels is that there are switches inside, which I'll get to in my next episode, which keep track of the position of each score reel”
Nicholas Backbone @ ~22:00 — Sets up follow-up episode content; hints at complexity of Midway system
technology_signal: 3D printing emergence as viable solution for reproducing obsolete EM coupling components like Midway's nylon score reel couplings
medium · Nicholas Backbone: 'Now that we live in the fantastic era of 3D printing, it may be possible to replace this nylon coupling fairly simply, but at this point if you were looking for a new nylon coupling you'd be 100% out of luck'
neutral(0)— Educational, technically detailed presentation with balanced assessment of trade-offs. Backbone acknowledges both strengths (Alvin G. long-term reliability, craftsmanship) and weaknesses (service difficulty, metal corrosion). No advocacy or criticism present; factual, informative tone throughout.
