I have an Incra jig. Its a nice tool for doing things like cutting finger joints (or dovetails-I haven't progressed that far) on a router table. I bought it to build boxes for smaller cameras. I have no idea what it would be used for in a 6' tall camera.
I think it would work equally well on a table saw as on the router table for doing things like finger joints. It is provided with a set of interchangable ruled scales to position the fence for finger joints or dovetails of varying size, widths, and patterns.
I've also used an Incra miter gauge in a woodworking class I'm attending and that is another very useful and precise tool. It will probably be my next tool purchase.
