COMPLETING THE SPAR DECK FRAMEWORK

GUNPORT FRAMESSection 3.1
Not much in this section; however, there are a couple of typos that need to be addressed in Gunport Side Framing (page 8): first, in paragraph 4, the second gunport is 1/8" forward of Bulkhead R (vice 3/32"); secondly, there is a gunport 1/16" aft of Bulkhead K, which was left off the list. This gunport is on both port and starboard sides.
There also is a reference to the "bridle port" in this area - which I believe is the port entry to the head area (not bridle port). The bridle port is addressed later in Chapter 3, page 36 - when installing sills and side frames.
As the practicum mentions, the catheads do not fit and must be modified. I find it easier to picture the cathead correctly in place first and then proceed with cutting a template, using the model, to give the same fit. I've included pictures below of the cathead properly in place, along with a picture of my template.
As an engineer, I don't like statements that don't definitively tell what to do; so I worked out what the cathead profile should look like before removing small amounts of material. My diagram above depicts what the end result should look like and took only minutes to shape, without any mishaps, thus emphasising the importance of having a clear concept of what to remove before starting. That is, looking at the cathead (red) you can see what has to be removed to fit around the planksheer and waterway such that the flat end of the cathead would fit flush on the deck; now it's a simple matter to proceed. I'm a firm believer in balancing out the significance (words) with mass (pictures).
Before leaving the subject of catheads, there is an interesting origination that can be applied to catheads. The catheads can be scratch built, using original wood from the Constitution. If this kind of thing is of interest to you, please check out my article on Adding Origination to your Model: Original Wood.
OUTER PLANKING, UPPER HULLSection 3.3
LOWER GUNPORTSSection 3.4
There is one gunport that needs to be addressed, the one in the vacinity of the entry/exit port. There is an important relation that needs to be established such that the hull entry/exit steps don't get in the way of the gunport. See a picture of the steps and how the steps exit in the center of the entry port and are not in the way of the gunport; check this alignment to avoid problems later on.
MAKING A STANDSection 3.5
I ordered a base board from Model Expo and purchased a couple of turned legs from my friendly local ACE hardware store. Put a 1/4" groove in the top of the shortened legs to acommodate the keel, drill holes in the keel and legs to acommodate two short 1/8" brass rods, glue the legs to the base with Weldbond and Voila:
I now have a display stand.
NOTE: I made a change to the pedestal heights when I got to Chapter 9. The model should not be horizontal but have a forward incline; that is, the aft pedestal should be about 1/4" shorter then the bow pedestal. See my correction to the pedestal in Chapter 9 for additional details.
