Knife maker Bob Warner, one of the moderators on the CDK Forums Tool Time forum, has a website which contains a nice group of tutorials on building some of your own shop equipment for knife making. One of his tutorials contains the diagrams and a parts list for building your own electro-etching unit.

The following is a detailed description of how I built one of these units, and a list of the tools and parts used. Thanks to Bob for making the original information available and his willingness to share his knowledge. Bob’s website is www.warnerknives.com.

Parts and Supplies

Almost all of the parts that I used for this box can be purchased from RadioShack. I would recommend ordering them from their website, www.radioshack.com, because you will stand a better chance of finding everything that you need than you will at one of the local stores. Another advantage to ordering from the website is that you will not have anybody trying to sell you a new cell phone or 60 days of free internet service. There are a few miscellaneous parts that you will have to get somewhere other than RadioShack. Most of these parts can be found around the shop or at Wal-Mart.

Tools

This is a complete list of the tools which I used. Not all of these tools are necessary, so if you don’t have something here, just use something else. Most of these are pretty common shop tools though.
