    Roger's comment triggered further photo browsing and the thickness proportions provided by Mondfeld (sorry for misspelling his name in my sketches) are different from what appears on the pictures I found showing Bluenose blocks. The internally stropped blocks have a thinner outer shell and also look thinner in between the sheaves when there are many of them. Attached are the proportions I guessed by looking at pictures. Note that the drawing provided at p.243 of Mondfeld's book are out of proportions. When drawn using the numbers he provides, the blocks are much thicker than they look on the drawing, owing to the thicker cheeks. Again thank you all for your willingness to share knowledge and resources! Cheers, Simon

    Using the designated inch value as the shell height and applying Monfeld's proportions to the sheave diameter provided in the catalog, I had to scale my block model down by 23%! It now looks much more plausible, doesn't it? I think I'll go with that. Thank you very much! Cheers, Simon

    allanyed, I had checked Chapelle's previously but too quick perhaps: at p.347 it says: "(From Merriman table of vessel blocks)". A search online for that caption led directly to Merriman Bros. 1928 catalog, which listed sheave dimensions for various sizes, from which I am going to try Monfeld's proportions. We'll see what comes out of it. Will post the results here in case anyone's interested. A big thank you to all of you! Cheers, Simon

    Thank you druxey, will try with that and see how it compares to what I initially got. When I superimposed the blocks I had with a rigging plan mine were almost twice as big: Cheers, Simon

    Thank you Gregory, I saw this reference as well during my research, but the block size I am looking for is expressed in inches, not in rope diameter or circumference. So even if I use the excel tool I end up not knowing which size block I should pick from the results. I just want to make sure I start off a good base before I go on and make 144 blocks by hand! Cheers, Simon

    Hi, I am busy building a model of the Bluenose and in Jenson's book the blocks use in the running rigging are all listed as "13-inch triple", "12-inch double", etc. I would like to know which dimension the 13-inch refers to: sheave diameter? Something else? Also what proportions should I use to determine shell height, width and thickness for each type of block? Are Monfeld's proportions also applicable to blocks from the early 20th-century, or is there a better resources for that era? Thanks in advance for your help! Cheers, Simon

About the NRG

If you enjoy building ship models that are historically accurate as well as beautiful, then The Nautical Research Guild (NRG) is just right for you.

The Guild is a non-profit educational organization whose mission is to “Advance Ship Modeling Through Research”. We provide support to our members in their efforts to raise the quality of their model ships.

The Nautical Research Guild has published our world-renowned quarterly magazine, The Nautical Research Journal, since 1955. The pages of the Journal are full of articles by accomplished ship modelers who show you how they create those exquisite details on their models, and by maritime historians who show you the correct details to build. The Journal is available in both print and digital editions. Go to the NRG web site (www.thenrg.org) to download a complimentary digital copy of the Journal. The NRG also publishes plan sets, books and compilations of back issues of the Journal and the former Ships in Scale and Model Ship Builder magazines.
