The bike shop owner also said that I might want to consider what frames I'm using since all steel frame tubing material is not the same and there might be some compaibility issues wih different steels when it comes to welding. Some frames use chro-moly tubing, other, cheaper frames use other grades of steel. I have an old Fuji MTB frame and the guy said that Fuju uses their own grade steel unique to them whereas my Raleigh frame uses more common chrome-moly tubing, etc. Dunno if this is all true or not, just relaying what I was told. Maybe someone else with more materials knowleedge can chime in on this and clear things up.
