Rib Flange Deburring Tips - Anyone???
Does anyone have a secret trick to reaching the tight relief-spots on the rib flanges? I've been attacking these things with the shoe-shine technique and some emory cloth. But it's still taking me forever and becoming quite tedious. 
Anyone have a special trick they use to speed up the process some?

Phil,
Try the scotchbrite wheel. Should take most of it off.

Practice...
Come on up here for practice. I think I have about 14 ribs left on the bi-plane to finish.

When I complained to Gus at Van's about the Slartibartfarst* thing, he said "don't waste your time. It's more important that you smooth the flange so that the skin fits smoothly over the nose of the ribs."
This is done with a bench disc sander or scotchbrite wheel. Sometimes the skin on the tabs gets pretty thin but he said not to worry about it.
Hope this helps.
*Slartibartfarst is the designer of Norway's fijords according to Douglas Adams.

But my ribs will have fabric over them. Smooth edges become a little more critical.

Sears sells mini scotchbrite wheels that fit in a dremel. About an inch in diameter and maybe 3/16" thick. Worth their weight in gold...I have never found them anyplace else but Sears...You can cruise through a rib flange in about 2 minutes. Once they wear a bit they get even better...Loved those things...don't care to see another rib flange for a long time

Very cool. I'll head to Sears tomorrow and see if I can find a handful of them.
I've got the major portion of the edges under control with a die grinder and mini scotchbrite wheel (1" x 1"). Having one that's 3/16" thick might be the ticket.
The real problem is the area between each of the tab flanges. Those are a royal pain.

The fastest way I found for those relief notches was to go around them with one of those hooked swivel deburring tools to take of the edge, then clamp the rib in a soft jawed vice & give a quick smooth with the emery cloth - shoeshine style as you say. But I didn't try the dremel, that might be the go.

Ladies and Gentlemen,
Let me introduce you to the coolest website for jobs EXACTLY like this. All aluminum oxide and made of various shapes and sizes. Deburring just got a whole lot easier.
