Wing Rib Prep (Part 3)
This past Tuesday I finished fluting / straightening all the ribs so today I started deburring them. The plans tell you to debur them before fluting them and you know, there's a reason for it. Basically, once the flanges are fluted it makes anything you run down them wear a little more, whether it be Scotch-Brite pad or wheel on a die grinder. It's not really that big of a deal, but I do think the deburring would be a little easier without the flutes in there.
This is tedious stuff, not exciting in the least. I should start seeing some wing structure in a day or two. I still need to think about where I'm going to run the holes for the wiring conduit.
Here's my trusty el-cheapo angle die grinder. I like this thing because it's small, light and cheap. I've seen other builders spend crazy amounts of money on a pneumatic die grinder...sorry folks....as long as it spins whatever is sticking in the end, it works for me. I think this one was something like $17 bucks at my local Sam's Aviation Hardware store. Notice the grooves in the Scotch-Brite wheel from deburring lightening holes.
The only problem I have with this grinder is that it blows water / oil. I have an in-line water catcher in my air supply and the thing catches a LOT of water...I would say maybe 1/4 cup in 4 hours of work. I guess it's just SO humid here in Georgia that I may need to put another filter in over my workbench where my coiled hose comes down. That would probably help catch a lot of it.
