Electroetcher Information Page

Introduction

This page provides some information on a home made etcher for etching knife blades. I built one of these etchers by following the instructions on Chris Crawford's web site. Chris provides very detailed instructions on assembling the etcher following a design that was originally created by knifemaker Bob Warner.

I used a couple of different components than what are listed on Chris's site while building my electro-ecther so I decided to include a list of the items and their prices. Additionally, I had a hard time working from Chris's step-by-step wiring instructions and really needed a wiring diagram to help me visualize and understand the electronics. I produced a drawing of this wiring schematic and have included a link to the document at the bottom of this page. Providing this wiring schematic to whoever may need it is the primary purpose of this page. I hope it helps you.
