Aluminum Main Gear Shaping

Does anybody round the leading and trailing edges of aluminum main landing gear? Will it weaken the gear? And how did you do it?

Just curious if anybody does this. I was thinking a belt sander might be the second step but curious if this affects the aluminumís strength.

As long as it's sized properly to start with, there should be no problem with finishing it to the degree you're willing to do - though you may be the only one that notices. Nothing wrong with hitting it lightly with a belt sander if you like.

Thanks. The sharp edges seem to chip easily and just want to clean it up a little but a little concerned about annealing the aluminum and making it softer..

Yes.....the Sharp edges can cause cracks and failure.....much better to have a smooth edge.

After an hour with a file, wet/dry sandpaper, finishing with acid etching primer I am pleased with the results.

People might find this a bit crazy, but if you can find a router bit that has the proper shape, in this case a 1/16-in roundover, it's very easy to machine. I do recommend something other than high speed steel bits however.
