re: Bump-out Verticals

Paul, that’s the second time I run against “grease paper” . The third time it was refer to as lard paper.
I understand it’s for lubricating the blade as it cuts.
Some people use wax paper, the one we use to cover food.
Is the lard paper simply a paper covered with a thin layer of lard? The grocery store have a pack of lard. can I simply melt some and brush it on a paper just like when they make pastries?

Which one do you use?
