I tried installing a 'cliffy' protector on the center "wabbit" hole on Space Jam maybe a year ago to cover some hole wear.
The Cliffy did the job appearance wise but the ball wouldn't "settle" down in the hole anymore. It would bounce out due to the extra metal.
I think the wood in the playfield helped to 'soften" the impact but once cliffy installed, the ball would not deflect off the back angle metal
deflector and stay put in the hole.
I don't have that cliffy protector anymore but was wondering if anyone else installed one and added some kind of foam impact pad to "absorb" the force of the ball deflecting off the angled back deflector to reduce the force.
And if it worked for them when they added padding? If so, may re-invest and try the cliffy again.
Long shot but thought I'd ask.
