Edited Date/Time:
So, I was going to change my rear wheel bearings and the retainer stripped itself upon removal leaving material in the threads and it looks like even fusing some of the material in there. I even used the tool and didn't just bash them out. I have a race next Tuesday I was hoping to make but it doesn't look like I'm going to be able to now. Does anyone have any ideas of how to fix this?
The shavings you see are from me spraying it out with WD40 and wiping out what material would come out easily with just a rag. The threads on the other side seem to be largely in tact and most/all of the material seems to be from the retainer itself. And yes, I peeled up the bearing seal after the fact just to see how they were.
Here are a couple angles:
A 47mm(48mm?) x 1mm tap is about $130-140 from what I can see and I really don't have any other machining tools though. One friend mentioned something about a thread files, but that doesn't seem like it would work too well.
I'm not opposed to just getting new wheels or hubs but having them overnighted Monday may be prohibitively expensive and I was looking to find a way to get these in shape by Tuesday. Any thoughts?
