I have been match reaming v.s. match drilling my #40 holes in thinner materials (e.g., skin to ribs) with nice results. My #40 reamer has a small point that helps maintain alignment.
On #30 holes through thicker materials (e.g. angle and spars) I am not getting such nice results when match reaming. Typically the bottom hole of the thinner material becomes a bit oblong or less round.
My question is, can I match drill to 1/8in (i.e., 0.125, slightly undersized) and then separate the components and ream each hole to #30 independently? Will they align well when I go to rivet if I do this? I figure this will give me some room for error when drilling.
