Default Fluting issue

These parts are far from flat/straight and the instructions say to flute, but how in the world are you supposed to flute material that doesn't exist due to the scallops? Am I supposed to flute closer to the holes? Or do I need to grind down the tool so it reaches further in on the flange?

Ok, I think I answered my own question, lol. Fluting closer to the holes seems to work. Dummy.

Fluting where you have you tool positioned in the photo works fine as well.

Probably doesn't show up that well in the photo I guess, but that was the problem - there was exactly zero engagement of the upper tang at that point. I would have had to grind down the lower two tangs of the fluting tool to get even the smallest amount of bite.

I have a fluting tool with nylon jaws that easily grips the full width of the narrow flange. Maybe ask around and see if you can borrow one with better jaws.

Default Fluting Issue

As always there are alternative tools. I have one similar to this, it might work better for your application.
