CNC cutting fish

After our fish went over so well the first time, here, we figured it would be a nice thing to donate some more fish to a cancer fundraiser for my father-in-law.

A few fish prepping for a bath.


Trying something new.  I never enjoy grinding mill scale off steel so a 4:1 ratio of Muriatic Acid to water does the job for me.


What the fish look like after the acid dip, compared to the hot rolled material it came from. Bye bye mill scale!


Scotchbrite and blowtorch, works every time. They were sealed with boiled linseed oil and a coat of carnuba wax.


Mixed it up by adding a copper rod to the muriatic acid and leaving these two pieces in at the same time. Semi plated them with copper and gave it a translucent pink hue.
