Quoted from partyguy1516:
Going to instal my new ringmaster kit. How do I remove the top plate? Is my screw just mangled? If so will I have to drill it out?[quoted image]
If you've got some gumption & the right tool, you can use a Dremel w/ a cutoff disk & carefully widen one of those Phillips slots to be big enough to accommodate a flathead screwdriver.
I've done it plenty of times, but never inside the sensitive environment of a pinball machine.
You'd have to do some seriouspants shielding/masking to contain all the debris.
[Whoops, saw others recommending the same.]
Try a small Phillips driver--tap it in gently w/ a hammer, tapping as hard as you're comfortable. Use as much downforce as you can while you back out the screw.
Or you get can some success w/ a stripped-out Phillips head (not really stripped in this case, so technique may not apply) by tapping w/ a small flathead screwdriver w/ hammer to try to bite into one of the remaining slots on the +.
There are also screw back-out tools that can bite & back out a screw, plus a sort of barbed mesh you can stuff in a stripped screw & then cram your Phillips into it to try to get purchase. But those 2 techniques are more for stripped-out heads, where the cavity is too large to grip w/ your driver. Your screw has the opposite problem...
Please report back after giving it a go--this is golden information to share!
