What did benjamin franklin mean when he said that the convention spent much of its time "sawing boards to make them fit"? give at least two examples of the "boards" to which franklin was referring.

In my point of view Franklin meant that they spent much time revising issues so that they wouldn't have the same same issues later on
Boards is Constitution , Sawing is Changing  and Make them fit is Change the constitution so they see fit.So basically changing government to however they wanted.
The treaty-making process, The structure of the national court sys­tem andThe amendment process are the examples
hope it helps
