Multi slot mortising machine

I have always used a home-made slot mortising machine for my mortise and tenon joints. My previous slot mortising machine was made possible because of a lucky surplus sale find. But I had always wanted to be able to build a mortising machine from scratch using readily available materials. I have finally achieved building such a machine, and this article describes how it works.

You can also see a Tony C's slot mortiser
based on the plans on on LumberJocks.
Tony also has a lot of
photos if it's construction on flickr.

These articles are also available in German
