Woodworkers travel mug is made from stainless steel with the lid being stainless and plastic.
This project can be made by using a solid timber blank to turn the outer section of the mug base or the out can be staved or segmented to make a very ornate mug.
You will require a blank of approx 160mm long by 90mm diameter if using a solid peice.
Stave construction is also another alternative.
