you got it almost right.
simply clip between -1 and 1.
the waveshaper will do the rest.


in your arithmetic approach you missed a cord from output of clip~ to  
the right side of the first multiplication.
but it will still not work like that, i believe.

ps: there seems to be a long standing bug (or misunderstanding on my  
side) about lookup~'s table size.
anyway, you should make sure your buffer is actually at least 513  
samples long, and compute the wavetable with 513 (0 to 512) rather  
than 0 to 511. (larger table sizes won't hurt, but improve your  
results).
