Step 9: Base: Drilling the Column
I simply measured 4 holes and drilled them. It was necessary to countersink the holes for my bolts because my bolts were too short. If I had purchased the bolts new instead of pulling them from the trash, this would have been unnecessary. Since I have already collected tons of bolts, it was worth the small amout of effort to countersink, and it saved me ANOTHER trip to the hardware store.
I used the Harbor Freight Tools clamps to hold the column on the base and used the holes in the base as a template for drilling. This assures that everything lines up neatly and that the column is straight.
