The Stripping..

The bare frame was there..
With the proper tooling in place now, the stripping could start. I really had been looking forward to it and could not wait to see just the bare frame and fork. The majority of the parts of course just need a few hex keys to remove them from the frame which is done easily and a very nice exercise. What struck me was that some parts were in fact still close to brand new. Especially the brake calipers, seat post, stem and handlebar. Also the derailleurs were very neat, the rear in particular. 
The crank had some wear and scratches, as is to be expected, but came off very easily using the crank puller. The bottom bracket was a different story however. The locknut ring was stuck so tremendously tight that, despite the use of the proper Shimano TL-FC31 wrench set, I could not get it off unharmed. What did not help is that the nut is manufactured out or rather soft aluminum and the cutouts were damaged immediately when the wrench shot loose upon the first attempt. After the locknut was finally freed, the internal bottom bracket was easily removed. Before removing the crank I had already felt some slight play and its condition turned out to be rather poor indeed, with a worn protection sleeve and a considerable amount of dirt inside the bearing house. The frame inside tube ends in the bottom-bracket section however were totally free of corrosion fortunately. What was left was the headset. The drive-out tool did a fine job removing the bearing holders out of the head tube, which needed a few firm taps only. The crown race could remain as intended. I had my bare frame now..
