How to strip a thread hub: A tutorial
I've started to overhaul my wife's 20 year old Raleigh 10-speed for her to use as an in-town errand bike. I was feeling good, picked up the tools and parts, and have been working on it a bit each night.
Tonight I was going to remove the 5-speed freewheel, something I had done with my bike of that era. I had the correct 2-prong freewheel tool. As suggested by a helpful LBS mechanic, I used the QR skewer to hold the tool against the freewheel to prevent slippage. After tugging a bit with the tool in a vise, I finally got the freewheel to turn.
It started coming off OK, but then bound up a bit. Fearing that I'd strip the threads, I backed off, and started again. Again & again.
To make a long story short, by leaving the #$*!# QR on, I prevented the freewheel from screwing off the hub and stripped the hub threads. Rats! ALl I have left are the 5-6 threads closest to the hub. I feel so stupid. Now I can add building a wheel to my overhaul project, once I can find a used 120mm 36 spoke rear hub.
