Hi All,
Does anyone have a design for a tool to flatten the rivets in the leading edge of the flaps and ailerons?

cheers Bill

I have a small tungsten bar to rivet the leading edges to the ribs, a long skinny one for the ribs to spar and most everything else I squeeze. Helps that they are soft rivets.

Oh those front ribs you install center ones in leading edge first, then install leading edge

Mike, I like that you used a single piece leading edge.

I made a bucking bar that fits inside the bulkhead with a bit of room to spare for the rivets. This one is for the -12. The -18 has a radiused leading edge at the front.

I have a smaller one than this that was made from a scrap of tungsten used to weight Tennessee walking horses feet. Bought this one at Oshkosh. https://aircraft-tool.com/shop/detail.aspx?id=ATS6005
