Minimum Materials costs for a Gingery lathe
The following is not to be used as a shopping list. It is for the sole purpose of getting a general idea how much this project costs. It is incomplete and highly unreliable. You have been warned! This list assumes you already own a complete woodworking shop, drill bits, safety equipment, etc. It also assumes you make no mistakes, no waste, know exactly what you're doing, and is generally unrealistic.
See the attached lathe-bom-sort.html for a more realistic idea of what you will be spending...It's what I actually spent during the time period I built the lathe. --fenn
