Bill,
Thanks for the help, hopefully I got it right, but I think I erred on the overdone side. I'll tell you something, it got really crowded in there when I was finishing the main mast. The halyards were especially a bear.
I was using Pastor's "Ships of Columbus" as a guide since the instructions were worse than useless; however, Pastor did not have much on the Nina rigging so I had to improvise a bit using the mizzen for the Santa Maria as an example. I was thinking of scratching the parrels but gave it up after the halyards.
I thought that the main halyard would be the easiest.....but it actually turned out to be the most difficult. Maybe I should have used different blocks like the other two masts but I was sort of laser visioned on the sister blocks and really wanted to use them. The hardest part was finishing off the halyard lines at the cross piece that slips into the loop on the spar. I started by tying off one end of the line at the cross piece, slipped the line through the sheave, down to the top block, through that sheave and back up through the sheave to the cross piece. I then tied the end to the cross piece in situ which gave it a slightly slack look.
Overall, I am fairly happy with the finished product and now I need to finish the Pinta and Santa Maria......as well as the PT Boat and Dreadnought, etc. Although, I am going to have to give my hands a respite first.
Thanks again for the help,
Steve
