There is no reason to need a lathe to make a dish.
The First Nations from here in the Pacific Northwest never had lathes and nobody cared.
I. have no lathe yet I carve dishes of several sizes.
The first thing to do is to select some wood. These shake blocks are western red cedar.
The fresh and colored ones weigh about 18kg, the old weathered block is dark brown and maybe 10kg.
They are 60 cm tall and split to follow the grain with no knots whatsoever.
The old block needed to have clean surfaces and end cracking sawn off to maybe 45cm.
