Problem Solving

07 Feb

Frame repairs are a case in problem solving. In the last little while I have had two instances where most people would say “time for a new frame”or “too far gone” . The first involved a warrantied tig welded frame that the company replaced after viewing it online and asking the owner to cut through the bottom bracket shell beside the frame number. They got to verify that the frame couldn’t be ridden again and replaced it. The original problem with a broken dropout was fixed by a friend of the owner. Adrian brought it to me and wanted to know if I could do anything to keep the frame going. He wanted a second bike to use around town. I had a long think about this and decided to apply a patch along the BB shell. While I wouldn’t say it looks like bought one, it will be good for many more k’s.

The second was a case of two broken bottle bosses in the downtube of a plain gauge tig welded frame. Ordinarily in a lugged frame I would suggest we take the tube out and replace it. This frame made that both difficult and un-economical. I decided once again to apply a patch over the whole area with new bottle mounts. Again the frame will do many more kilometers before it needs to be replaced

I don’t do this sort of work lightly and I dont see this as the easy way out. A patch is rarely as good as a replacement but in both these cases I believe they will last and are well executed. They are also quite visible but I do attempt to be elegant at the same time so I am not hiding anything when I do them
