  1. Hi Brett I have acquired a ZC 21 and don’t know how to use it or if I would use it. I was just wondering if you know what it would be worth? It has all the attachments and instructions with it. Regards Damien

    1. I paid $1000 for a machine with all key parts. Motor ok. Belt old but ok. It needed new bearings and a fair bit of work.

  2. Hi Brett,we have a Zinken 21 compact type 79 machine that requires three new prismatic locking bars,if you can help we would like a price including freight to New Zealand.
    regards Jim

    1. I have a Zinken 21. I have been trying to find replacement locking bars for the planer head. The old zinc ones have expanded and cracked.
      I have been speaking to an enginer in Wellington who can make 3 new ones for around NZ$600. Not sure if anyone has good originals for sale ?
