Steph,
I was nervous about drilling into mine for the lamp rod mod. I found step drill bits at Harbor Freight ($7-$8). Worked like a charm. I applied Blue painters tape, marked, used a center punch, drilled a pilot hole then used the step bit to go to 1/2". Whole thing took less than 5 minutes to install.
Good Luck.
