How's it coming Mckee? remember that a good rule of thumb for a straight limbed bow bow is that the length of the should be double that of the draw length. Also since you have a stiff handle section that isn't working you will lose a bit of drawlength. with a 101cm stave you will be looking at about a 41 cm draw length here. just don't pull it back further than that. you can add some draw length to it by allowing it to bend through the handle, or recurving the tips (probably not the best option for a first bow).
best to leave the limbs full width for most of the length then taper the last 15cm or so to nocks that are about 13mm wide.
