So I just made a small contribution to this forum because you guys have helped me in the past.
I have wrenched on cars in my life (Classic VW Bugs and kit cars) and also firearms. I have enjoyed the pinball experience in life and acquired 7 machines over the last 15 years. When I first got the machines I employed a "local guy" to repair them but when I saw how easy it was to just solder a loose wire I started to work on the machines myself.
All my machines have "mint" play fields but I am digging deeper to restore all my machines. I was in Las Vegas last year at the pinball museum and had a conversation with the tech "gal" she said to replace all of the coil sleeves on a restoration so I got all the coil sleeves for my 7 machines and also all new rubber bumper parts, also kits to rebuild all the flippers with the correct gaping tool and new bushings.
That black coil dust is AMAZING!
I've been using break cleaner on the coil dust for the metal brackets and it works GREAT!
I had been using HOPPES 9 but the brake cleaner is superb!
Anyone use brake cleaner on these parts? Can't see a downside?
Best thing about taking all the coil's out is to clean the brackets and replace/lube the parts!
Some of my diverters in ATM and ST TNG needed much love for some lube.
I've posted some pics ... ATM had a much work needed, it worked fine but new coil sleeves make it work better!
I also replaced the coil bracket from ATM which was oblong from use and "bubba" but in non standard screws for the flipper bushing which I replaced.
