My evening sunlight :

Following research of the most adapted solution for these  sheaves :

In progress, wiev of upper great walnut wooden block :

Following research :

Too difficult, indeed, no visible solution :

Two general views showing relative size of the new reduced block :

Beginning four sheaves block's remake at right size :

After frenchies, I've to reduce size of my sheaves : too large... To remake is also to make...  😀

Other tests :

Following with a new simulation :

Other pics :

I received this morning my 5 mm new sheaves :

Hi Mark,

You are the winner !

Two sunday pics for your perspicacity :

My romance with Niña :

The heater went to install the electric radiators, size seems good, I'm winter ready...  😘 :

A little quiz :

There is a great error on one of the two pics of my prevent message

Could you find it ?  😀

I made two pics of sails, after Madrid Museum (up) and Pastore (down) : only difference I've found, a little horizontal mast behind stern

All block's notches prepared for sheaves and cringles :

Following the manual preparation of all blocks :

Completed simulation of the bottom block :

Two pics of bottom block :

Thanks Louie da fly  😀

A french expert told me that the lower block was around 1480 an archaic block articulated on a cringle

(Halyard knights arrive later)

I would add that a large 600 kg antenna requires four reals, even using a capstan, otherwise, hoisting would be difficult

Three reals is good for the misain mast, not for the main mast

Finally, the pulley followed the inclination of the mast, (8° on the Niña), that is the reason why it was articulated

Later, the halyard knights followed the same angle as the mast. (Otherwise, they would break quickly)

I think that such a disposition prevented the problem of twisting rope you met on your referenced model

Christian
