The pen is built using aged maple dyed with cordovan colored dye,to cut the wedge I glued a 1/2 blank to a reach stick and set my chop saw ( 7 1/2 ) to the setting that ran from
the upper corner of the blank to the bottom center and did the same on the reverse.
The saw has a lazer so it was just a matter of repeating the alignment.both pieces of wood should be the same size.
the ports are made with tubing that I picked up at a hobby shop and filled with inlace.
Turn and CA as needed
