Deburring...ad nauseum

[Thunderpig]

In the process for prepping my HS for priming and the deburring is endless, as many of you know. Anyone have any working experience with the E-Z Burr line of products?

I do have a set and have used them but they are not my first tool to grab when it comes to deburing. They especially can come very handy when you don't have easy or no access to the other side a hole and works better on thicker material as oppose to the thin skins that is on the rudder or elevator.

That's why I have a recliner and a frig full of beer in garage. 3m deburring wheels work great for edges. As for the holes, grab a beer and go at it.

..is that you'll end up with lots of deburring tools in your toolbox, before it's over. Personally, I prefer to use my scotchbrite wheel whenever possible for all edges. If the skin is too big for that, I have 1" diameter wheels I use to debur, chucked into a drill motor. For holes, I either use my hand debur tool, with a countersink bit screwed into it (although it's slow, it's precise), or I use a small 1/4" diameter countersink bit that chucks into my battery operated drill (it's faster, but be you must be careful not to over do it). In the end, the important think is that your are deburring things. I have seen a project where nothing was deburred, and it was hard to look at. Nothing was seated well (i.e. spar caps, skin overlaps, etc) and if you reached into the project at all, you risked cutting yourself on a lightening hole or other sharp edges.

Good thoughts above, the only comment I'd add is that you'll feel a lot better about all that deburring on the HS once you get started on the wings.

A lot of us would be shocked at the lack of deburring in some production aircraft facilities. Nothing more than knock the big chip off of the back side of the hole, if that.

Keep your standards as high as what makes you happy.

Deburring holes can be tedious, but goes fairly quickly. What drives me crazy is deburring all the tight spaces between flanges on ribs and bulkheads.

I use them and love them. Doesnt work everywhere and i've ruined quite a few of them using my Sioux drill. I now use them with my Dewalt cordless.

If i'd ever do this again, i would definitely use it from the start.

One other note, reamers make much cleaner holes which makes deburring quite a bit faster imho.

I'm speaking primarily about the skin holes...just as a measure of saving time...and my deteriorating right rotator cuff! I do so love those scotchbrite wheels...the skin edges are proving to be a bit of a pain, I don't like the excess vibration, so I use the 1" drill wheels, though those open blade deburring tools look like they would help a great deal. Good news is, all my HS parts are deburred and primed...dimpling and riveting planned for tomorrow, provided I don't get called in to fly at work.
