If not, no worries, I'll get ahold of one soon.
I will try and pull the axle clean it up and take some acurate measurements of length and ID at both ends. I will use some drill bits to try and get a profile of the ID end to end. I dont want to modify the BRP axle if I don't have to. close to the end where the nut tighens the axle it narrows to 11/32 or maybe to 5/16.
I was considering the tapered ID of the axle. I was thinking of making a tapered bushing or possilby a tapered axle. My concern is that the trailer axle will not stay square to the bike frame or cause the trailer axle to bend in the bike axle.
Are the axles welded to the frame or are they removable? Have you completed the first 5 yet?
