I was in your same position experience wise when my buddy wanted me to shape him a 4 stringer Tbanded monster. The blank was $198.
take your time and go nice and slow and you won’t have a problem.
Biggest convern for me was the rails where the stringer met the outline. I used a sharp hand plane to bring them inline with the rest of the rail… and then a curved exacto wood carving balde for final shaping in this area. Worked real well and the board came out super nice.
