This video shows how to install a Futures SUP handle with a couple of simple jigs. The router is set on high at 20,000 rpm and the homeland jigs are only held in place with tape. Futures sells a really slick jig for doing this step that allows you to route both the hollow cut and the deep cut without moving the jig. I get around this alignment issue by using the handle placed in the deep cut to align the jig for the shallow countersinking cut.
