Quoted from SilverballNut:
Yeah, I've considered sanding the suckers...
Honestly, my airballs to the ramp have almost completely stopped since I centered the drop target in the slot (it was aligning itself all the way to the left and leaving a gap on the right) and I raised the drop slightly so it is level with the cliffy, not level with the playfield. This way there is a single rise to the drop/cliffy and not the little hump from the drop and then the rise to the cliffy.
Out of curiosity how did you align it left/right? Was thinking I could just enlarge the holes on the metal frame to slide it a bit over.
Also, leveling with the cliffy seems to have helped tremendously. I really want to keep the cliffy on there since there were signs of wear already.
Quoted from delt31:
I can confirm that air balls did begin to occur after installin cliffys. After looking into it, I determined the drop target itself wasn't flat which likely happened during the installation of the cliffy. After tweaking it I have no air balls anymore. Bottom line, don't take off the cliffy - you will need it. Just make sure the drop target is aligned properly.
Challenge for me is/was balancing how to align, since the cliffy raises the level a bit and hard to make it level with the pf and clffy without tilting the target (which I may do with a little styrene shim). I think Silverball's comment on leveling with the cliffy will help, or at the very least, splitting the difference. Definitely agree on keeping the cliffy on there!
