I have a question. With the Hawk you have to bottom feed. With multiple holders you can change blades fast, but up from beneath it is. I'm working on a large size project with many, many holes and find it really difficult to find the small hole to feed through towards the middle of the piece. I tried marking them with a red sharpie but no good. Does anyone have any tips or tricks for doing this. It is doable but , pardon my English it sucks...............Craig
