Re: pic: OmniSwerve Pivot Top View
The design assumed use of a CNC router so that would be used to do the pockets (multiple passes, depth of cut isn't that great but its certainly doable). I also made sure not to pocket it all the way...

Re: Most underrated/undervalued tools
This thread has very quickly gone from underrated tool to favorite tool (I'd even call a lot of these tools overrated). The best answer I've seen is the vacuum cleaner. (basically) Every team needs...
