If any of you followed my Basso Loto thread you will remember that I had the right side rear DO re-welded and then did some finishing work with a Dremel tool. The low temp brazing is not in my wheelhouse right now. Back in the mid 80's we had the torches and jigs for frame building and often would replace the entire DO. But I don' have those torches anymore. If a lower section can be sourced I suspect we might be able to weld it on the frame. I know Harry Havnoonian still will sell some frame supplies and is an E-Bay store under HHbicycles. Lemme know about a possible re-weld o the DO. Smiles, MH
