Beginning mech restoration of an otherwise-perfect PJW30 'Robot' and discovered that Deck 2 is missing the sprung pulley on the back of the take-up spindle. A hopeful check of the innards dashed my hopes that the missing part has come off and lodged itself somewhere. So, if anyone has one of these sitting around in their 'spares' box, let's talk. I have attached thumbnails (I hope) showing Deck 1 with the pulley (white top under "57"), a caliper measurement (it's 15mm diameter) and Deck 2 without the pulley. Thanks in advance, Nick.
Springs and small screws are like gold these days, here's a guy on Amazon with a big set maybe one will fit. He also has a ton of pinch rollers. https://www.amazon.com/Repair-Minimal-Spring-150-200-Pieces/dp/B07H64X81W
Thank you Mister X. Amazon had never occurred as a potential source but now I see all sorts of useful stuff there! Cheers.
