Got the Herters Model 5 fulcrum's wire strung this morning and it meets all of George Herters bombastic sales hype!
Took several attempts to get the .006 in SS wire stretched without snapping the wire. Then I broke it once more setting the zero by adjusting the 2 nuts on the end of the beam. After that using RCBS scale weights in increments of 5 grains to 200 grains it was spot on. That lever on the pointer end is use to settle the swing of the beam down, right now. Very clever IMO.
This was a fun restoration. I know this photo can't express how much I enjoyed doing this project. No it won't replace my Lee Safety Scale or M5 or the Gen6 but it will get admired, by me, for a very long time.

Thanks for the suggestions. The fly tying wire worked.

When setting a job up for myself it must be Idiot Proof as well, as I am a bigger idiot than most people I know, and I prove it to myself everyday.
