I ordered some of the 2.4mm basswood to play around with I’ll share how it goes. If my math is right and it rarely is it should be between the 1/11” and 1/9” wide pegs
Haven’t decided how I’ll point them yet but tempted to start with alternate cuts like this
==/==|==/==|==/==
And just see how pegs like this

will behave
Edit - yah that math is wrong 
anyway 1/11 is 3/33 right? So pretty close
