Reciprocating Sander for Grooves

Here is my hacksolution to truing up deep juice grooves. Deep juice grooves have end grain on both sides, so it’s both difficult and important to sand them well.

Rotary tools (like Dremel) are nice, but extensive use of those can yield a bumpy and uneven surface. The reciprocating sander solves this due to the straight bottom and back & forth movement. it also helps prevent rounding over the edges.

Grooving.

Dental work.  This is a good reason to use a metal-cutting reciprocating saw blade, as the teeth are smaller and will be easier to grind off.Photo Feb 24, 6 35 15 PM (Medium)

The 5-minute epoxy is pretty viscous, but I didn’t want to wait for the 30-minute epoxy to cure, so heat allowed the epoxy to flow better into the kerf.

It took about 4 minutes to get the glue spread, so it only took a minute of holding the blade in place before it held on its own.Photo Feb 24, 6 43 35 PM (Medium)

This worked amazingly well.  In the future I may make a taller one, so that the reciprocating saw body doesn’t get in the way of the board.  That way I don’t have to switch sides of the board when sanding (as seen in the video below).
