What tool do I want for deburring the inside of rib flange holes?  The avery swivel doesn't do it.



Maybe I could stick the head in the end of the 90-degree drill kit... hmmm.

I used a Scotch Brite Wheel (small) on an adapter for the drill.

Thanks, but I meant drill holes, not lightening holes.  Those are easy

enough to do.

I'm assuming you're talking about rib flange rivet holes in areas too tight 

to get a conventional deburring tool or a large drill bit.  Just run a 

scotch brite pad over the holes, then prime 'em (if you weren't priming 

everything already) since you will have removed alclad.

Stick it in a die grinder -- I shoulda thought of that.



But I'd imagine you want to have a real light finger deburring that way.



Thanx.

Well, today I was facing the same problem deburring the holes in the rudder 

ribs near the trailing edge.  The flanges get really close on the last few 

holes.  I ended up making this doohickey out of a nail.  You stick the shank 

through the hole from the inside of the flange, then grab on the shank with 

your cordless drill.  A couple rotations of the drill (in slow speed) and 

you've got a nicely deburred hole.  Took me about 5 or 10 minutes to make the 

thing and it can debur any hole where there's at least 5/16" between flanges.

Have fun,

There are any number of accessories for use in your Dremel tool or my favorite, a pneumatic pencil grinder such as ball files or stones that will reach those problem areas and deburr structural parts just fine.

Creative!  Thanks for all the replies on this - I need to learn to think

a bit more 'out of the box' on this stuff.



I did end up doing those holes with a dremel bit held in my fingers.

I use the swivel debur on the lightening holes and wiring holes.  On

smaller ones, I use sandpaper or scotch brite.  The key is to knock off

any rough spots that might start stress cracks.



Van's guidance is if you aren't likely to cut your finger on the edge,

it is good enough.  I go further than that.  



HS is relatively thin material in most places so knocking off the edges

is pretty easy.
