When siblings pursue shared interests but clash over learning approaches

My brother and I are both trying to learn woodworking in our dad's old workshop, but he approaches it like an engineer with precise measurements while I learn by trial and error, and we keep getting in each other's way both physically and mentally. We want to honor dad's memory by using his tools together, but we're starting to argue about methods and space, and the whole thing is becoming stressful instead of meaningful.
