I drilled out a hub for a women’s tribute build and actually recommend using a vice and a cordless variable speed drill (I have three drill presses and a mill). The hub material is relatively hard and a drill press might tend to cause the bit to grab and break. Which ever tool you you use, just go slow and steady. After drilling the holes to the proper size, I used a larger bit to chamfer the holes on each side to allow the spokes to seat well in the holes. I also recommend using high quality preferably US made high speed steel bits. As recommended in earlier posts, I used a later Bendix marked front hub. Unless you get real close and read the markings, it is very difficult to tell the difference between my real G519 and my tribute hubs. I think it would pass a two foot test!
Great job on the build!
