Thanks for all the great suggestions on the Centerline Challenge. I read them all and even took some influence from some of them.
I think that the simplest and possibly most elegant suggestion was to keep the piece in the form and set the form on the bench and simply scribe a line using the bench as a reference. The only reason that I didn't adopt this method is that it only marks one side, and sometimes I need to mark the other. To which, I thought the idea of leaving a gap in the center of the form panels to allow a pencil was a great idea!
I also loved the notion of using a shadow line. While it may not apply here, I have a feeling that it will be used in my future.
On the wishful thinking front, I'd love a laser that could just burn in a line. As you will see, a great many of the suggestions hit on my solution. So here is my take,
Here are a few stills of the jig in action. I loved the comment that my solution would be elegant, but not so pretty, I guess you folks know my affinity for the grotesque.
Thanks again for all the brain power, I'll be tapping it again soon!
