How to fix stripped 17mm wheel hex? - Page 2 - RC-Monster Forums

IM not saying to ca the thing in place. the epoxy acually fills the gap and when cured should form a nice hex shape, if you dont go overboard on the stuff and cake the whole hex then you will be able to get it out.

to each his own.

I am guessing this pic was before Ben got on that "tanning" kick... He looks a bit darker now IIRC!

I epxoyed one of my 17mm rim hexes that was rounded about 3/4 of the way into the wheel (nut came loose and only rounded part of the rim). I put a film of grease on the wheel hex so the epoxy wouldn't stick to it and I could pull it back out of the rim easily.
It worked well for me, but maybe if yours are badly rounded put some grooves in the rim a bit like aqwut did, then the epoxy should have more chance of holding onto the rim. Does JB weld work on plastic? Maybe that is stronger than epoxy.

Thats what i was thinking - does the grease on the hub affect the epoxy?
Would wd-40 work as a release agent?

if you were looking at the side of the hex, not the face, maybe it would be clearer. If you looked at a wheel mounted on your truggy, you would see the 17mm nuts face.

Now, looking at the side of the hex on the truggy, drill and tap an m3 hole. You would be drilling and tapping the round part, not the flat part. Now make slots on the wheel that an m3 screw will go through and thread into your newly tapped hole on your hex.

something something loose nuts blah blah whatever

In the second picture you can see the screw head sticking out of the hex and through the slot in the rim.

If you are using wheel hub/hexes that have no extension, you can use a longer pin that holds the hex to the axle (drill bits work if you can't find the right pin). The part of the pin sticking out of the hex goes into the rim to do the same job as the screw aqwut used.
If you are using extended hexes then the pin will miss the rim and you would have to drill into the hex like aqwut.
Even if you slot the rim to put a srew or pin in personally I would still use the epoxy for extra strength.

i've used drill bits, jb weld, two part epoxy. Your best bet is new wheels. You could make it work, but only for so long. Keep your nuts tight and you won't strip a hex. I know you said it was due to cartwheels or backflips or drug muling from el salvador or something but 17mm wheels just don't strip with tight nuts.
