Pickup coil winder

[petemoore]

  This machine has a 25 to 1 'counter' shaft [vertical, used for the cam driven zigzag or buttonholeing I guess].
  So with a 25 turn clockface [from paper and felt tip, tape], and a takeup reel mounted to the 'counter' shaft, and a color coded count-thread wound on the 2nd take up reel, I'll have a sure fire, accurate counter system.
  Between the count thread color code reads, the 25 turn clock face under the counter wheel pointer, and a black mark for '0' on the bobbin flywheel, I'll have a super simple and accurate count system, indefinitely stores count.
  Daft, the only thing I need is a steady-pull take up bobbin like on a cassette, cassette deck is too big though.
  I just tested it doing 1.5 wraps down around the drive bobbin [just a metal bobbin shape on the top of the shaft], and also 3/4 wraps [less likely the thread will catch on itself], both drove the thread lentgth with no slippage...provided I had a take up 'reel' helper keeping tension around the drive bobbin.
  I don't know how a take up reel on a casstte drive system works exactly, if it were as simple as using the motor direct drive...that'd be nice, a PS and mounting system would make a much better self contained counter.
