I seen Dan's (Bergerud) bowl that he give as a example to someone today I did the carve and didn't like the way the outside edges didn't line up, but Dan struck again... He made me start thinking, so I made what I wanted for three boards on top of one another 2.25 thick. Question #1 how do I get the file into the STL folder..#2 How is the feather made for each board for the cut out...I get these two ? answered and I'm going to get this 3-d going to do the minor things and start learning how to do gimp to keep stepping up.
