      <title>Dovetails - Incra Jig Process Improvement</title>

        <![CDATA[<p>Had some trouble with getting the Incra Ultra to cut joints the way I wanted consistantly. Loose joints drive me crazy! Anyway, I set forth to tighten things up with a process approach towards improvement. 

	<p>The system now cuts near flawless 1/2 blind and full dovetails about every time. I&#8217;m looking forward to progressing to some of the more advanced joinery thats possible with the Incra system.</p><br /></p>


	<p>Of particular note: I replaced the slightly chewed up runners on the base of the Horizontal fixture with custom made plywood/polyethylene replacements. Extended them another 2&#8221; out the back from the originals for added support. The polyetylene was cut from a large cutting board purchased from sams club. That stuff even joints nice! The fixture slides much better now.</p>
