How are you guys getting all the little aluminum chips & bits out...?



Everywhere where a curved radius meets a flat spot is a place for a chip to hide.  Like between wing ribs and wing skins; or between lower spar caps and bottom wing skins...



They seem stick to cortec, even long after it's dried.  Maybe it's a static electricity sticking type of thing here?



I've got most of them out by running a vacuum cleaner, blowing with compressed air, "flossing" with a toothpick, vacuuming some more.



But you can't get them all.  



What are you guys doing?  Am I being too much of a perfectionist here?



Thanks,



Pat

And you never will. Get them out as best you can but don't expect to get them all.

When I'm doing a little work in a section with crevices that can catch chips

I block them off with masking tape.



The best approach is prevention - do what cutting you can before you

assemble the parts. This is more of a goal than a reality.

Here is a tool available commercially, but I always

made mine out of aluminum.

Hey guys,

   

  Maybe it's just me, and that's why it takes me so long to complete anything, but my building sequence takes care of the chip problem.

   

  Assemble, Drill, Disassemble, Deburr and Corrosion Protect, Re-assemble

   

  By treating each part like it's a piece of jewelery and cleaning it thoroughly before re-assembly, I don't have (and wouldn't allow if I could absolutely help it) chip one in my airplane. I've also heard that there are DAR's out there that are very picky about the chip thing, and in my opinion anything that can get between two surfaces and act as a wedge with the proper amount of vibration is not good.

   

  I'm not using Cortec for the very reason that it's sticky and will hold chips in place. Now bear in mind that that's my choice, so anyone's opinion out there isn't going to change my mind, because I'm an adult and capable of making  my own choices and decisions. *grin*

whether it is purchased or home made be certain to polish all edges of the chaser to a fine finish with fully radiused edges. Otherwise the cure can be worse than the illness!

I'm using cortec too. I avoid this problem by doing all the drilling, trimming and deburring on the complete subassembly before I start to apply the cortec.

So how are you guys doing your nose skins and upper skins on your wings...?



I do the "assemble, drill, disassemble, deburr, cortec, re-assemble" process as well, but in many cases you have to continue by building upon a portion of the structure that's already completed.



I think the masking tape idea sounds like the best "real world" solution so far.

Hey Patrick,

   

  Excellent question. I just waited to rivet all of the skins until the entire skin-fitting process was done - leading edge included. I ended up having to dis-assemble the entire leading edge and remove the top and bottom skins so I could deburr the spar cap angle and clean out inside, but getting the chips and shavings out and deburring is that important to me. Since this is my hobby and I have no social life, the build for me is really about doing the best job I can - not necessarily the quickest. I'm definitely not the speediest of the bunch.

   

  Tape works great, as well as compressed air. Just don't seat chips and shavings deeper into nooks and crannies by blasting on them too aggressively with an air gun. I'm coming off sounding like "Mr. Clean", but just ask my wife, that's definitely NOT the case. There are actual aluminum shavings in my bed. Scary.

Like Debo I too assemble everything and drill everything to final rivet size.  Then it all gets taken apart, deburred, wiped down with alcohol or lacquer thinner, then I use a two part self etching primer.  Let it dry 24hrs then reassemble it and rivet.



If I have to drill on the assembly, all chips are vacuumed.  A chip chaser is also handy for getting the burrs off of mating metals.

		To All...

			When it comes to removing those pesky little

chips, one can buy a chip remover and turn loose of some hard earned

cash, or..... get hold of an old hack saw blade. Using a small grinder,

bench mounted is best for control, and grind all the teeth off of about

six inches on one end. Then use the grinder to notch that end to sort of

a hook. Then, carefully, grind it on the flat sides to make it thinner

than it already is. This thin hook will reach into those small angles

and remove most, if not all, of the chips. Cheap and effective.
