In my box bulding, I have been using a lot of thin strips for accent pieces, including miter splines.
Since they need to be accurate and consistent, I need an easy way to sand them. Although I own a Timesaver wide belt sander at my door shop, I do this work at my shop at home, so I don’t want to make the trip unless I’m really doing a lot of pieces.
I have a floor model Jet spindle sander, so I built a simple jig that bolts to the top.
It is simply a fence with a pivot hole at one end, and a slot at the other to adjust the thickness.
I feed the piece from one end—be sure to hang on—it will shoot out the back side. After getting the piece fed far enough, I reach over with my left hand and pull it through. It is important to maintain a steady feed speed, as it will dip if you slow down or stop. It is usually better to set it a little thick and make several passes.
Doing both sides will clean up your saw marks.
I drilled and tapped two 5/16” 18 hole in the top to accept the bolts
The jig can easily adapt to a bench top spindle sander, or even a sander on a drill press.
Thanks for looking
