I spent 2 hours tonight getting 2 HS-404 ribs to lie absolutely flat. I fluted, straightened, fluted, straightened so many times I forgot what got me there.
I was Dazed and Confused.
There must be some Science to the Art.
I first get the flanges to 90 degrees. I use a piece of cheap aluminum angle I had around to verify the 90 deg.. From that point on it is a mystery. I start by laying the rib on the web. I will notice that one 'corner' or 'side' is high. Where should I flute to get that high corner or side to relax??? Van's instructions and the threads on this site seem to suggest a willie-nillie approach - just start fluting. If it gets worse - straighten out with seamers and start over.
It's like being a bank robber with six weeks to figure out the combination of the vault.
Someone must have come up with a basic methodology for fluting based on the configuration of the part.
If you have, please share it with me.
Thanks in Advance
