Interesting set of jigs

First one is for making thin cuts on a tablesaw. Its a bit different take from other builds I have seen for this. Second on is for a rather fancy paint spray can shaker. Third one is for moving sheets of plywood (nice build but a bit overkill). Forth is for a portable router table, I actually could see myself making this one. The last one is for making a sanding wheel to sharpen tools on with your drillpress.
