Le Rochefort yacht de port de 1787 au 1/36 ( monographie ANCRE)

Good morning. Lovely work. I love the kit jig which determines the correct position and height of the deck clamps. Boy I wish I had one for my Enterprise. I think I must have redone the clamps more than once to get it right. Cheers Grant
 
The square tree-nails look great and the smooth
This brings up a question. Were they actually square? I cannot imagine how they could bore a square hole or why. English ships used round copper clench bolts for the most part through the keelson. There was a period when treenails were used as well alternating with clench bolts. Did the French ever use clench bolts or just treenails?
TIA

Questo fa sorgere una domanda. Erano davvero quadrati? Non riesco a immaginare come potrebbero praticare un buco quadrato o perché. Le navi inglesi utilizzavano per la maggior parte bulloni rotondi di rame attraverso il paramezzale. Ci fu un periodo in cui venivano utilizzate anche le unghie degli alberi alternate a bulloni di serraggio. I francesi hanno mai usato i bulloni di serraggio o solo le unghie degli alberi?
TIA

Thanks Frank, great drawings! I like the figure eight heads as well as the square heads. Would love to know where these and square head pyramid nails were used on French ships. Maybe for planking?? I doubt they could or would try drive a spike through the keelson, floor and into the keel instead of boring a hole for bolts.

Hello je pense que c’est les extrémitées des boulons qui on un écrou carré
 
Depends on the era, Threaded bolts with nuts did not come into use until the industrial revolution began in about 1860 and beyond, nearly 100 years after the Rochefort was built.

True, but rivets with square roves were use as early as the 9th century (perhaps earlier) on Viking vessels. I'm not saying that's what is used here, just pointing out what a fastening device with a square "head" might be.
