Part 20: Upper Bulwarks and Top Rails
The new wood strips arrived after a long wait (badly damaged package but fortunately the strips were OK -
UPS!) so I could get to work on the uppers.
The upper bulwarks and top rails: These form a band around the ship and sit on top of the main rails (
See Image Part 10 ). Their construction is straightforward but a lot of measuring is needed to get everything correct.
On the ship, the upper bulwarks are fabricated from wooden boards that are attached to risers fixed between the main rails and the top rail. Around the stern they are made from shaped wood blocks and along the forecastle they are iron panels. The sections at the forecastle deck are split to allow the catheads to fit through and the toprails run over them to meet the Knights head.
A feature of the upper structure is the decorative panelling on the inboard side.
The Inner Decoration on the Upper Bulwarks.
The inner white panel is the painted wood and the decorative moulding is set between the risers. The decorated panelling starts at the heads and runs the length of the main deck and along the straight section of the poop deck but is not continued around the stern. The inner bulwarks are painted white on the forecastle deck and are varnished wood around the stern. There are 40 panelled sections per side. The top rail is positioned so that it rests on the risers on the inboard side with only a small overhang outboard.
The top bulwarks are about ⅓ the height of the lower which works out at 4.8mm high on my model. The Billings instructions suggest using a 7x1.7mm hull strip for the top rail which is way too wide for the scale so I went for 5x1.7mm sapele strips for the upper bulwarks, 3 x1.5mm strips for the top rails and pieces of 1.5 x 1.5mm strip for the risers. To give me the 40 panels the spacing worked out at 15mm with (approx.)12 x 2mm for the white panel decor.
Because the white panels are a feature that will be very visible on the model I tried to make them as best that I could. After a few trial attempts to paint them onto some scrap strip I was not very happy with how they came out. Masking and hand painting was a waste of time because the paint tended to creep along the grain and under the masking and it was difficult to paint all the panels identically. Using an airbrush wasn’t much better so I tried painting some 2mm strip sections (rather like I did the decoration on the deckhouses) and gluing them on but it was a bit messy and I didn’t like the result so I abandoned that method as well. I had some 2mm BECC white gloss lining so I next tried that, the lining gives nice crisp edges and can be precisely cut and positioned however, I could not cut the semi-circular ends (a straight cut looked perfectly fine) and I was going to go with the lining but since I had just been playing with the MF70 to make the catheads I tried using it to mill out the panels. I used a 5mm wide C channel piece to act as a jig so that I could centre the strip and then cut out the panel to a depth of 0.5mm using a 2mm end mill, lift the cutter and then move on to the next cut (Note: the strip is only held in the channel lightly so remember to clip the end with some scrap to stop it moving - lesson learnt!). When I reached the end of the bed travel it was then very easy to wind it back and slide the strip along the channel and repeat.
It didn’t take too long to cut out all 80 panels and I was able to make them all identical in size and spacing. It was then very easy to flood the trench with gloss white using a paint pen. I was very pleased with how the panelling came out and it was definitely worth the extra time to try out a few methods.
I steamed a separate piece of strip to go neatly around the stern so that the ends joined the two side strips along the poop deck and then painted the outer in semi-gloss black and glued the riser pieces on. I trimmed in the two short pieces for the forecastle deck allowing for the camber of the deck and painted the outer black and inner gloss white. I attached the bulwarks using some white glue and brass wire to pin them into position
The top rails were not as straightforward as I had hoped. I started with some 3mm sapele strips but they had a tendency to split along the grain as I was bending them and I certainly could not steam a piece of the sapele around the stern without splitting the wood. Fortunately I ordered more than one type of wood in anticipation that I was going to have problems and decided to go with some walnut for the long lengths and some flexible beech strip to go around the stern. The only issue was matching the colour to the main rails so I mixed some different wood stains and found cherry wood/mahogany stain at 4:1 was close enough. Scale is always a problem and even 3mm width is too wide for the top rails so I reduced them slightly by rounding the edges with a shaper to 2.5mm stained them and then pinned and glued them onto the bulwarks. Once all the glue had cured I gave the main rails and the top rails a coat of semi-clear.

Next: I should probably have fitted the portholes earlier so they are next on the list. I also need to do the gammoning of the bowsprit and attach any details to the beak because I will need to make and fit the upper decor and name plates and they will be in the way if I do them first.
