Check the TT archives. W3LPL uses a modified 90 B for tensioning his 5/16"
guys. I have modified my guage ala W3LPL to accept 5/16 EHS. I am looking
for calibration information from anyone else who may be using the 90 B on
5/16 EHS. Otherwise, I will have to create a lookup table based on my own
calibration tests.
With a little filing, the 90 B can measure 5/16" cable at a cost of $39
versus the $130 PT-3. The 90 B also measures 3/16" and 1/4" cable that
the PT-3 does not (requiring another $60 to buy a PT-2).
For my purposes, the 90 B was a better value.
