Spent time this evening preparing the HS Inspar ribs. No real issues here. I did have difficulty cleaning up the sides of the flanges neatly. I had been using a piece of emery cloth just by hand. It was quite a slow process, so I made a fairly simple tool from an old hacksaw holder around which I strug a piece of emery cloth. I am not sure how others do this task, but it definitely increased my speed for this boring task.
