The reversing screw under the playfield operates dry; no lubrication for the slot. This offends my engineering sensibilities because we have a stainless steel follower that rides in the slot. I'm unsure of the material used to make the reversing screw itself. A magnet won't stick to it, so what's it made of? Hard-anodized aluminum?
Has anyone in this club had their reversing screw wear out?
Thanks
