Fingerboard radius is usually measured in inches..you can't measure a radius in degrees, so you need to clarify that. Does he want a bevel under the low string, which is fairly common for a stand-up bass? Measuring that in degrees would make sense.

Does he mean 7-9 inch radius? If so, you would draw a circle that has a 7" radius, then use the outside of the circle as the pattern for the fretboard.

Just seen that - it's so time consuming, and not a particularly easy way of making an accurate block. I've made short sanding blocks using my router and the extension rails plus a centrepoint. I took some scrap 1/2" plywood: cut a circle out to whatever radius you want the fretboard, discard the centre cut-out, then cut the surround that's left into 3 inch wide segments. Carefully stack and glue the segments together - I used screws to permanently clamp them together until you have a block. 8 segments will give you a block 4" long which is fine for making a radiused 'board. You need to stack and glue really accurately, then clean up the glue and sand out any uneven bits.

another way ,if you know anyone who works with steel,is to cut a section about 150mm longxabout 100mm wide out of a piece of 800-900 mm diam pipe

What I used as the neck on my cigar box cello was a recycled piece of an old wood porch column. It was made in sections so each one had a nice radius.
