Jesse, I want to lighten the tips up some with the trapping. I see no need to run the full length of the limb.
Here is what enables be to do temp sensitive bow building steps. It will use up all the oxygen, so I cut it off before working. My garage door has a 1"+ gap all around the edge, so I feel pretty safe.
I mark the center line on front and back of the riser. I then draw the site window, front and back to act as guides. Then it's on to the hacksaw!
Some careful work with a hammer/chisel and rasp gets me to this stage.
From here I use my Rigid oscillating spindle sander to contour the grip. When the major facets are cut, I will switch to my 1X30" belt sander and a 4 in 1 rasp.
