I could have sworn I had more pictures of this, but Im sure you will get the point. So, with your handles securely attached, Take a saw and cut of excess. You may also want to use a wood remover. After you get most of the extra off, take the dremel with the sanding wheel and begin sanding it down. You want to make the edges round and maybe also put in nice finger grooves. Trust me, it makes it much more comfortable.
