I'm getting ready to turn some reel seats for some fly rods I'm building. I have some pecan wood and would like to turn a shallow spiral cut (like a barber pole) and stain it with a dark contrasting stain. Now, I'm new at this. What would be an easy way to cut uniform spaced spirals? Also, what would you recommend as the best way to finish it as it will be exposed to lots of water? Thanks in advance for your help.
