Forms a fillet rather than a butt joint, so possibly more torsional strength.

Is that the case? I always thought capping a tube or any box section it would do the opposite

Are we referring to where the fork end is proud of the fork blade. Or the finished end of the blade on the drop out?

If you file the fork end flush with the blade its a butt joint, left proud it forms a fillet.
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?

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...

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
