Stalagmoneter 

.

Where to buy a "STALAGMONETER" for plating bath additive/wetter determination? Also, where to get those different size rings for old Barret SNAP additive determination? (Hey- Don't call me an old-timer!!!) thanx, Dave

You just missed the last thread on this, Dave. See letter 4369.

Stags-I used to buy them from JPS in Cincinnatti,OH. Kocour used to sell them also. Rings-I made my own from 316 SS weld wire, tig welded and polished. Calibrated them in the lab using a Stag. Had a set from 1" to 5".

Also remember using a ring after converting to SNAP-A/M. Ever see nickel plate look like corn flakes on a part. The extreme gross excess of A/M made the plate off the scale on a contractometer test. For the newer folks, the moral is the anti foamer in A/M prevents you from using the ring test.
