I would suggest you take a class to see if you want to tackle it first. Then, count up what it would cost to get started. Quality
hand planes can be very expensive. Go to http://www.rodbuildingforum.com
and post your inquiry in the bamboo section. They can add their input and suggestions for classes, etc. There are some top crafters there. I have been to Oyster in Blue Ridge and he has some outstanding rods.
