Picked up a Frankenstein recently. I've noticed the pop bumpers seem sluggish.

I haven't done a shop job on the pin just yet. Would going to a larger coil size help? I'm used to the way Williams pop bumpers play.

Have you tried replacing the coil sleeves yet? Start with that first. I don't recall Frankenstein having weak pops. Either way, the coils themselves are not likely your issue.

Yeah, replace the coil sleeves first at least. Check the coil stops while doing that too and replace if needed.

I tend to go a bit overboard on my shop jobs. My typical shop job is usually 120+ hours. Needless to say, all coils assemblies will be meticulously rebuilt, new sleeves on everything, switches cleaned/replaced, re-gapped.

This Frankenstein has some potential. Just haven't dove into it yet.

I thought the same thing when I picked up my Jurassic Park. Two of the metal rings/rods were bent pretty badly so I replaced those but the real improvement came when I replace the DE plastic spoons with Williams spoons. Now the ball spends all day in those pops! Good luck!

do the Williams spoons need any modifications?

Pics of the Frankenstein I shopped and modded a year ago. Pops were very responsive after rebuilding.

Hi PoMC,

Nice looking game. People seem to bag on Frankenstein quite a bit. What do you think of the game play?

Nope. They are just slightly shallower than the DE ones, so you get more action.

I shopped and modded it for someone, so got to play it quite a bit. I wasn't a big fan of it after getting a lot of games on it. I like Sega pins, but this one didn't do it for me.

Do you mean the dip in the spoon is shallower so it moves more when the pin presses down, engaging the switch more often?

#12 3 years ago

Make sure everything moves freely. Novus2 the spoons, new sleeves, & set a 1mm gap on the switches. Mine are thunderous on all of my DE/Sega. Had that problem with all of them. Not anymore.

Yes. I have changed out all the spoons in my GnR, JP, and a buddy's BBB. All pops had much better action once they were swapped.
