Interesting adds for a workshop

First jig is to hold material down on a drillpress. Not so sure I would do this one. Second jig is an interesting feather board build with PVC pipe for the “feather”. I do like this build, but I think I would make it so you can replace the pipe parts every so often as needed. Third jig is for a trim router, basically giving it expandability options (handles, endstops, etc). Fourthis a contour duplicator…I think I would just buy a cheap one myself. Fifth one is a circle making jig to draw circles with, and then round over on a router table. my 2 cents, I would just make a router based jig.
