The bend on the backbone of the oif triumph frame where the filler cap is makes wall of the tube very thin at that pointI used to see quite a few hard tail conversions back in the day. They were mainly made from T120s, the first oil in frame models, that people found square and ugly.
Not ideal for welding a hard tail imo although a lot of people did
Such was the fashion
Personally I would not hard tail a fine handling frame like an oil triumph/BSA
