Replaced the offending (non-working) microswitch for the odd even scan. Looks as if it took care of the problem but the blade, for the replacement switch, needs some adjustments. Those switch blades have the usual adjustment that is achieved by turning a small adjustment screw. That darn adjusting screw is designed for Bristol tools. I have a few of those but not one quite small enough, of course! Wondered if anyone has a source for a set of Bristol Drivers? It appears Bristol sells them so perhaps I am captive to them if that is what is required. Ebay, has little to choose from. I'll need a set since I do not have a clue as to the proper size for a Rock-Ola machine. Thanks for your ideas and thoughts!

Hi David,
I forgot all about them thar thangs--till I saw this post. I have one or two, of them--got them years ago, I THINK, from Granger supply ?
Maybe they still sell them --worth a check ?? May also have come from "Mac Master-Car" (sp?) ?? Ron Rich

I posted this reply here to someone else in January 2017 "On another forum it was stated that the Bristol Spline is a 4 flute #76"! Norman.
Edit-- moderator-- Thanks Norman--just made this a "sticky"-- Ron Rich

Hey Ron: This company sells complete sets of Bristol drivers:
Also, look for Xcelite # 99PS-60 Bristol spline kit. I use it on Bell & Howell 16mm film projectors since they use lots of Bristol head setscrews.

Thanks, Ken, I'm thinking I have that kit--looks familiar ?? Been a long time since I saw it-may be in my old tool box ? EDIT: Just remembered where that kit was-- my best friend had it sitting in his tool box, which we used when we worked for/on Westinghouse products together -- that was in 1961 !! WOW--- !

Rockola 1478 is singing once more. I, being so frugal searched for more of those Bristol tools and after about a hour of digging through some old toolboxes found them! A small set of "L" wrenches. Still not a complete set but did have the 4 spline one that was needed. Some days it pays to be a hoarder! I could not find a number on it, but as jukenorman mentioned , it probably is a number 4. I, not being too smart, wonder why the Bristol Spline screws? Perhaps a jukebox saboteur might sneak in with his Allen wrench, in the dark of night, and change the adjustment if they used plain, old hex Allen screws? Were those microswitches the "Achille's Heel" of this era Rockola? This was the first failure I've had. Thanks Ron, Ken and Jukenorman!

Hi David,
After having had several conversations with Mr. David C. Rockola ( a super nice guy, from my perspective), it would be my guess, that he (or his purchase dept.) found a cash of war surplus Bristol screws-- Buying the tool(s) wooda been more "frugal", then purchasing "Allen" screws. --LOL Ron Rich

When I talked to the Bell & Howell technicians that designed the 1500 series 16mm projectors, they told me the reason they chose Bristol screws is because you could tighten them better than Allen heads.

Ken,
I think that's debatable-- IF, using "gen-u-whine" Allen Brand screws( which Seeburg eng. insisted on till about the early 70's), the space for the wrench tends to be much deeper then on the "copies", giving one plenty of "crank-down" room ! Ron Rich

WOW! David C. Rockola - What an industrial giant he was! He was not a shy man. I know he built all sorts of things. A friend had a Rockola Motor Scooter. A great Rockola read here in link below! A long time ago, when I first discovered jukeboxes, I thought the name Rockola must've had something to do with Rock and Roll music! Duh! www.madeinchicagomuseum.com/single-post/Rock-Ola Mr. Rockola spent six months in jail. He would not testify even after being given immunity. A very interesting story. |

Hi David,
Thanks for that story--very interesting-- I assume from reading that story that my guess above was correct-- like I said, he was very cordial to me--I can only recall one answer to my (many) questions--I once axked him "why so many RockOla jukebox "things" were so similar in design to Seeburgs?" His answer was a classic--"We shared the same design engineers--but,only, JP paid them!". Ron Rich
