[pianotech] Double loop German stringing

[Gene Nelson]

Conrad,
I have successfully made the jig that was designed by Ron Overs and it works 
quite well.
The nice thing about it is that the double loop can be made just a few 
thousandths larger than the hitch pin and if done correctly will not colapse 
onto the pin, nor will it unwind under tension - tag not really required.
Have the design and instructions on a .PDF file but I think it would be a 
good idea to get Ron's approval before I post it on a public forum.
