Make a jig for coves on the table saw

I had to watch the end of this video first to figure out what the heck the author was making. Basically its a jig so you can have beveled grooves in a board. Pretty clever idea. https://www.homemadetools.net/forum/coves-made-table-saw-fence-precise-duplicatable-77194?homelistings#post149883

A ball bearing pick and place machine

The author designed and printed out a robot arm with vacuum to move ball bearings around. Neat build and is more for the classroom than practical purposes.

Nice knob jig

Nice build for a jig to make knobs. Me…I just hand cut them for now. This build is nice cause it can be used for different number of grab points on the knob.
