The other knot is known as the bridle knot: 

    /---\
========|============bar
  &-----|---\
    |   |   |
    \-----\ |
        | | |
      /-|-/ |
      | |   |
      \-----/
        |
        |
      standing
       part
        |

That looks a little complex. Let me explain: 

First you pass the line over the bar, then end twice round the standing part, 
then poke the end between the knot and the bar. There is a stopper-knot at the end. 

As you tighten the knot, it slips until it stops against the stopper-knot.
thus the exact position of the knot can be adjusted by moving the stopper-knot
and re-tying. 

The bridle jig for the primary bridle is a long zig-zag line.
Near each corner of the zig-zag, there is a cross-mark.
Fix a smooth nail (I reccommend a plated pin) at each corner of the zig-zag.
Tie some 80lb spectra to the pin at the end of the zig-zag and wind it round
each pin in turn, till you can tie off on the last pin. 

Next, go round the jig with a magic marker (red for the low-power bridle jig
and green for the high-power), and mark the Spectra where it passes round each pin,
and also where it passes every cross-mark.
