Patrick, I am just about ready to start the mast work on this exact model. If you have not had much experience with model ship building, especially "square rigged ships" you will, unfortunately find this a challenge. I have completed 3 Bluenose, 1 Bounty, and 1 HMS Pegasus. Some of the problems with the Constitution I have found is, although there are 8 sheets of diagrams, there is a lack of detail in a number of areas. This means you have to rely on experience acquired from previous builds. Some of the plans refer to items that must have been included with an older version of the USS Constitution and revisions were not made for this model. The amount of the detail that is noted in the plans would involve the use of a microscope to do! If you include the detail suggested in the instructions you will need a well equipped workshop - not just the basic model boat building tools. The kit incudes enough wood to build 2 boats!! The problem is each bundle, even although they have stickers to identify the sizes, does not often provide the proper size noted in the instructions . This can be frustrating when you look for a size that is not there. Yes, you can just pick the closest size and it usually works fine. The self adhesive copper tape supplied for "plating" the hull I found to be a problem. It does not have "nail dimples" so if you want to make the final result look more authentic you have to place them yourself. Online videos of how to do this are available. There is just enough tape to do the hull, if you are careful. The problem I found is that in removing the protective backing the tape becomes very had to control as it tends to wrap around itself. I found using shorter pieces works. Once that happens that piece is scrap! So watch the waste as you barely have enough to begin with. I have spent 5 months getting to the start of the rigging (several hours a day). Looks like the rigging will not be much faster. Anyway, I know this sounds discouraging but it is meant to be helpful. If you take your time and improvise when necessary you will eventually get the ship completed and be pleased with the result I am sure.
