Cycles Spoke texture ?

Is it possible to make a Spoke texture using Cycle’s nodes ?

A spoke texture? Like a spoke in a wheel?

Yes like a wheel. I’ve just created a Snail with Shell and need a similar effect on the shell. I’ve tried doing it by sculpting but am having problems, using “add” subtracts for some reason and visa versa, so what seems an easier way is to use a material with displacement or bump.

Any suggestions ?

like this?

Yes, thanks.
