Quoted from Aniraf:
Can someone tell me if this little cover for the ramp lift arm is stock? As you can see, someone crudely screwed and glued the one on my PinBot together. I don’t know if this is needed.
This was covering the lift arm on that movable ramp to the left of the playfield.
That metal bar is stock. But it was just attached with thin double sided tape. It has the purpose of protecting the lift arm from ball strikes. Also it might stiffen up the long blue playfield plastic, at its weakest point. On most PinBots that bar has fallen off long ago.
