I'm going to cut down a 12" diameter hickory to make a bow to hunt with this coming fall. 
Searching led me to several posts indicating that I should wait until spring so its easy to get the bark off... but I dont currently have a bow & need time to practice with the new one before next fall. 
Should I cut it now or wait until the sap rises? 
FYI, my hands are not good with detail work, I doubt I could chase a ring if I practiced for decades (born with hand tremors 

 ).  Thats why I settled on hickory, & I'm planning on a classic flatbow.  
btw, am I correct that a hickory flatbow would meet these qualifications: 
- durable
- minimal detail work (eg no ring to chase)
- among the "easier" selfbows to make
