I got an email from Glen Rundel from the Melbourne Guild of Fine Woodworking in Australia with this image of their fleet of lasers ready to do battle! I love the Star Wars quality of their holding jigs.
I guess that once Greg Pennington's great laser idea got out into the ether, there was no stopping it from becoming a new standard. This photo even inspired me to get a couple myself, especially because I'll be teaching there later this year and don't want to look like a newbie!
This image really shows the benefit of using the laser for reaming. While you can do just a well with bevel squares and sightlines, let's face it, reaming a seat for the first time is challenging enough, and if this helps, great!
Glen, thanks for the pics
