I'm just about to try this and thought I should check whether any type of welding is compatible with the steel likely to have been used for a modest 1980s era road bike frame. I'd prefer to use an arc welder if I can.
The existing frame had 26.25 inch wheels fitted. It's difficult to find tyres for these wheels, so I want to swap the wheels for the more standard 700C size wheels, which are a bit larger (i.e. greater diameter). I need to extend the length of the front forks by up to an inch, so the larger wheels will fit and line up with the brakes. This looks relatively easy but safety come into it, because the front wheel will be depending on any welded joint I put in, when I'm flying down some hill at up to 25 mph.
