Thanks Raiden! The only tools I'm currently using are a Dremel, a drill, some sandpaper and files. I trace the stock scale for hole placement, shape, etc. I drill the holes first. I use a dremel to shape the outside of the scale. Lastly, after I'm sure all the holes line up ok I use a dremel to do the texturing and maybe use some sandpaper to smooth out any rough spots...that's pretty much it.
