Reconfigured my drill press to sit at the edge of my work table so I can drill the spar caps and spars. I spun the head on the drill press around so it would fit onto the table, and cut a couple of long blocks to keep the spar straight and level while drilling. I squared and secured the drill press to the table so it will drill exactly 90 degrees to the spar caps. I built the spacers to the height of the Avery rivet press, so I'll be able to use the same ones to rivet my spars when the time comes.
