Early 50s La Gazelle - Eau-de-Nil 🛠️ The Merlot Aftermath 🍷

I wonder this too imlach.....the extra weight of leaving dropout oversize compared to filling the open end of tube and filing dropout flush is kinda negated.....I wonder if it allows the tubes to have more flex torsionally and give more of a compliant ride?
That makes sense to me, filling and filing would make it more rigid..perhaps..?
 
I'm referring to the tubing being left open at the dropout.....there's a weight saving for sure over capping or filling .
Leaving the dropout tang proud of tubing I see no real gain strength wise!? Unless the dropout tang inside tube is birsdsmouthed...Iike a v maybe?
 
I can only assume strength.
By filling flush you will lose six small fillets of braze on the outside of the dropout/fork end so you could be losing 50% of the strength and more prone to stress fractures. Coming from the aircraft industry René Herse would have been well aware how important strength in highly stressed areas is over beauty. There are some striking similarities between the two, the lugs are short point with a side cut or mouth... could it be a René Herse or definitely in the style of...🤔

Yeah I get that..👍 but still I look at how proud the dropouts are left....I still see atleast a 1mm shave on the dropouts outer edge that wouldn't go near the tiny fillet puddle.on four dropouts gotta be another 15- 20 grams of steel....😁 Which is a fair chunk! My french weight weenie blood is rising 😆
