Ah, the things that one can make with just a length of dowel, a scrap of wood, and some random bits of hardware!
Today’s handsawgeek Poor Man’s Tool offering combines just those very materials to fashion an accurate and functional depth gauge for use in bowl, box, and vase turning.
Simply put, a length of dowel is sharpened on one end, poked through a hole drilled in a straight piece of scrap wood, and secured at various positions by a set screw held by whatever appropriate hardware can be found around the shop.
The biggest concern here as far as accuracy goes is that the cross –beam should be as straight and square as possible, and the hole should be drilled so that the dowel is exactly perpendicular to that bearing surface.
Besides turning, I can imagine many other uses for this device: Checking depths of mortises, dados, and rabbets, and checking depths of stopped holes being drilled. By turning the dowel around and using the squared end, this device could be useful as sort of a variable-length story stick.
Dare I say, that it could even serve as a quick gauge for setting the height of a table saw blade…
