For a recent project, I needed to drill several holes into some dowels.
In order to hold the dowels more firmly in place to be drilled, I made this jig.
I took some pieces of leftover laminated particle board, stacked them three
pieces high and screwed them together. Then I sliced them lengthwise at 45
degree angles. I screwed them together onto another piece of particle board
with the angles facing each other.
The angled pieces of wood support any dowel, pipe or other cylindrical
object that I might need to hold steady.
There is room left on each edge of the base so that the jig can be
clamped to the work surface (in this case, the table of my drill press) if necessary.
