Asking for any advice with this problem. I've got a DT Swiss RWS thru axle seized in a carbon frame, possibly overtightened, definitely corroded. The handle of the thru axle simply broke free from the steel male threaded rod which is still stuck in the axle, M8-1.25.
I've tried to soak the seized sections with penetrant, I've cleaned the threads and tried reattaching the handle with Loctite 262, after 24h the handle broke free from the Loctite again. I've tried placing a 12mm od spacer and nut on the threaded rod and tightening the axle in hopes of simply breaking the corrosion, but the class 8 nut simply starts to round and nothing else moved.
The drive side is a snug fit for a 6mm hex but not enough to apply any force. I can try to dremel flats into the threaded rod but the recess in the frame makes that difficult. I'm trying to avoid drilling the axle out.
Any advice?
