Quoted from Doug_Duba:
We were aware of the issue with the hole protector before Pinball Expo and were already working on a solution to make it stronger. Fortunately, the issue has been resolved. We spot welded in an additional .036” stainless steel liner to the existing part.
The part is secured without tape. As the screws are tightened, the rubber grommets expand to clamp the part into place. The modified parts have been tested and have shown no signs of distortion.[quoted image]
