Not a thing, with the right stuff.
The quick version is you're going to need to install a 1st or 2nd over bolt. (Or go the tapered route as was linked earlier in the thread.) Genuine Aircraft Hardware (moderators-delete out if their name shouldn't be in here) can help you out. I made a call to the vendor, borrowed tools, and fixed mine. I mean, this person I know that has an RV......
If you need the nut tight to have the leg tight, it ain't right and it ain't tight. For long.
At about 200 hours I notices a wiggle like you have on the nose. Tightened things up can called it good. Had to mess with a main a little while later noticed when I grabbed the rear of the pant it moved up and down-ish. A lot. Granted, it's out a bit from the axis so the motion is a bit exaggerated, but it was not right. Marked the top of the leg to the gear weldment, moved the pant, took a look.... sinking feeling in your gut. The nose wheel was lose again, too. Figured out all three of my gear legs were not even close to tight. If you built your plane, it's not a big thing, just takes a little time to fix. I see your profile has CNC machining as an interest, so I won?t bore you with the details regarding someone with no machining experience (me) needed to learn. (Luckily one retired guy in our EAA chapter spend his entire career locating and machining holes in things.) I ordered NAS6605-25X (nose) and NAS6605-29Y (mains) hardware from Genuine Aircraft Hardware. (Yes, I went 2nd over on my mains.
) They have reamers, too. Just make sure to ream out your flat washers.
Why did I have that problem? Lack of builder knowledge. Ream, drill, match-drill. Same thing, right? Nope. I knew the spar/wings were close tolerance bolts. Didn?t know that about the gear. It?s fixed now.
My experience showed the gear legs and bolt had almost no wear on them. The bolt had the cad plating start to wear off, but they looked amazingly ok. And they fell right out when the pressure was taken off them. The weldment holes are what got beat up. As Captain Avgas mentioned, it makes sense, since it is the softest material of the three.
I?ll get it right on my second airplane.
