This falls into the category of "theory & reality"...in theory making a drum kit from trees located on the family farm is a wonderful idea!...the reality is that fresh cut hardwoods take a LONG TIME to dry & this has to be done in a controlled environment. Even then, they sometimes split making them worthless for drum building. There is a very long thread on GhostNote by a guy who cut down some beautiful trees to make a kit...after over several years of drying (every one foot of diameter = one year drying time)...it split. Not trying to bum you out, just want you to know the time investment going in & the chances of everything going not so good. If you want to do the stave thing, start small & buy some cheap hardwood to experiment with & make a snare. If you & your dad can pull that off, you can start expanding. In order to make a drumkit you will need a VERY large lathe, and need to have a high woodworking skill level...imagine a 22" shell spinning at several hundred RPM's & controlling it. The guy that makes my stave shells is 54 years old, he started working in his dads shop at age 12 & he's still learning new things every day.
Like I said, not trying to bum you out or discourage you...just saying, slow down, do your homework & start small. If you've got a bada$$ woodworking shop or access to one & the skill to use the equipment, that's great...but don't spend thousands of dollars (many-many thousands) on something that in a couple months you say "I suck at this, what in the hell was I thinking?" LOL!
I'd suggest buying an inexpensive ply shell (Gladstone or Keller) and you guys build out a snare together, and see how you like doing it...I love building & pretty sure you will too. Just don't sell the farm (pun intended) to build a drumkit.
I'll sut-up now
