Welcome to rod building, you are going to have a fun time building your first rod. Me, I have building salt water rods for over 30 years to just learn I know very little about fly rods, but now back into trying only find that I can not wrap anymore. Just go to U-tube and watch all the rod building videos. So many! The only recommendations I have is 1) read the “Rod-Building Guide: Fly, Cast, Spin by Tom Kirkman” before you buy anything, 2) Rainshadows blanks are the best deal for price/performance.
BEST OF LUCK IN THIS GREAT HOBBY!
