Working with a RV-8 builder this weekend, we had trouble inserting the AN3 hinge bolts in his ailerons.
I knew that he had reamed the holes, and found he used a 3/16 reamer which was provided in an RV tool kit he had purchased used.
Some sizes...
AN3 - 0.189 max. diam. - ream #12 - which is also 0.189
A 3/16 reamer is 0.1875 - and that 0.0015 does make a difference!
So check your reamer sizes, and buy a #12 one for your AN3 bolts if your RV Tool Kit was shipped with a 3/16 one.
The tolerance on AN3 bolts is .003 total, so perhaps half of the AN3 bolts you have will be a slip fit into a 3/16 reamed hole...
