I use Duco Cement to temporarily laminate brass sheet to craft plywood before passing it through my Byrnes saw to cut strips.

Regarding downhill adventures, growing up in the 1950's in San Francisco was an adventure. The wheels were old "ball bearings" we'd get from the local auto repair garage or the wrecking yard, the axle was a whittled end of a two by four with nails driven into the end to spread it to a tight fit on the inside of the bearing. Brakes were the heels of your shoes. The teenagers in the photo had fancier brakes... hinged blocks of wood.

What Thukydides said. Very fine sandpaper. Use a hard sanding block so all you sand is the very edge itself.
 
Pumice or rottenstone will restore whatever level of finish, matte to gloss, that you want, but it will take a lot of rubbing to remove a masking tape "lip." Better to start with sandpaper in the 400 grit range and go finer from there.
 
The most effective way to avoid masking "lips" is to use a very thin masking tape (Tamiya or 3M Fineline) and apply your paint in multiple thin coats. When the paint is dry, carefully sand the edge down a bit before you remove the tape.
 
It's never an exact science. Not infrequently, you'll tear up some paint along the edge when removing the tape, or discover a spot where the tape "bled under" the tape, and so on. In such cases, there's often nothing for it but to carefully remove the defect by sanding and do the darn thing over and over again until it comes out right. This is one of the jobs that makes having an airbrush really worth the cost.
 

"Tow" is "short and coarse fibers of little value separated from the longer and more valuable fibers through hackling in the manufacture of rope. Tow is occasionally used in the manufacture of inferior qualities of rope." (International Maritime Dictionary, rene de Kerchove, 2nd Edition, Van Nostrand and Reinhold Co. 1961, Litton Educational Publishing]
 
"Tow" is also the short bits of fiber that break off of natural fiber rope, particularly hemp and sisal ("Manila") rope. On a large square-rigger, a lot of tow would find its way to the deck and collect in wet piles and muck things up. Hence the bosun's call, "Sweepers, man your brooms. Clean sweep down fore and aft." Another general meaning of "tow" is simply "worn out rope."
 
"Tow" was sometimes collected and saved for use in canvas pockets for padding of various sorts in rigging and so on, and for caulking material when mixed with tar to make oakum. Worn out or rotten line was often recycled into oakum as well. Quality oakum, however, was made not from lengths of worn-out line or "tow," but from new, long hemp strands. The highest quality new hemp line or oakum is made from the strong fibers from center of the stalks of the cannabis plant, which are whitish in color. (Oakum used by plumbers to caulk iron pipe joints is usually made from tarred jute or burlap.)
 
"Fibers and flyings" are what fill the air in a textile mill or rope walk and if you've ever been in a running textile mill, you will know that there is a huge cloud of fibers, little bits and pieces of broken fiber and dust, and "flyings" which are longer thin threads thrown off in the milling or spinning process, which must be continually cleaned up as they pose a large fire hazard. "Flyings" from the mills and ropewalks were used to make high quality oakum. 
 
Oakum is made by taking long fibers soaked in thick pine tar and simply twisting and rolling them into "ropes." The caulker has to prepare the oakum by unraveling lengths of the loosely twisted fiber from the loose ball (or "bale") of oakum and rolling the pine tar-soaked strands back and forth between the palm of his hand and the top of his thigh. (If you see a guy in the boatyard with his pants covered with tar on the front of his upper leg, he's a caulker! )
 
So, "The white ocham to be from flying & not from ground toes or decaid White ropes." means, "The white oakum specified here is to be made from mill flyings of the top-quality virgin white fiber of the plant and not from ground up tow or recycled rotten white hemp rope."
 
Quality oakum will result in a longer-lasting caulking job. Using old, weak fiber from worn out, rotten, or "decaid" rope will rot and decay in short order. The Admiralty wanted to use "the good stuff" because they didn't want to have to recaulk in short order because the stuff used was rotten to begin with.

Yes, exactly. For a 4mm plank width at the maximum beam, the tapering might be a bit tedious, but given the hull shapes of large vessels, as opposed to small craft, the tapering would be slight and generally at the ends of the vessel, particularly the bows. Remember when modeling that there is a scale to the length of planking as well as to its width. Plank stock isn't ever much more than 24 feet long in real life, given the limitations of tree size and handling. Given a scale plank width of 4mm at the maximum beam, there would be a lot of full length unspiled 4mm planks amidships, so that makes an easier job of it for the planker. (There are also standards for the spacing of plank butts which must be followed for an accurate scale planking job.) Keep in mind also that if the average plank width admidships is 4mm, when planking properly, there will be planks which may need to be wider than the average 4mm plank width to make everything come together without the need for "stealers." Kit manufacturers provide a bunch of pre-cut, square, finished on all four sides, strips for "planking." That stock isn't going to be suitable for all the planking at the size provided because planks aren't square.
 
You can find instructions for laying out plank in the "articles" section of the forum, so I won't repeat them here. However, if you lay out your planking at stem, stern, and each station (or perhaps every other, or even every three, frames or stations, depending upon hull shape and frame spacing,) You'll see that there's not much plank shaping to be done in the "wide open spaces" amidships.
 
If you divide the plank end widths equally at the bows, you should get a fair run on your plank seams and not end up trying to bend a "hook" in your plank seams. And sometimes plank width divisions vary, depending upon hull shape. A band of narrower planks at the turn of the bilge and wider planks (called "broads") in runs over "flat" areas is not uncommon. (In the drawing of the period planked hull below, note the "broads" below the turn of the bilge and running up to the stern post.) Planks in real life are gotten out of wider stock than the average plank width at the maximum beam. Plank stock in full size construction is often "flitch cut," meaning that it is cut as a rough slab sawn from the log, leaving the bark attached. These "flitches" are often slightly curved, as the log grew, which permits sawing out the curved plank shape to make best use of the run of the grain and lumber available. Planks are never bent across their width in full size construction, which is pretty much impossible anyway. Sometimes, a plank will be a bit "shy" and the plankers will "edge set" it by wedging it into place against its mate to get a tight seam, but edge-setting is a sign of poor fitting (which introduces strains on fasteners which can then let go) and not considered "best practices." Specifications sometimes go so far as to state, "no plank shall be edge set." When modelling with small stock of a species which will tolerate such bending, considerable stock can be saved by bending scale planks across their width to simulate what would have been a "dear" (costly) plank that in real life would have had to be cut from a very wide flitch, leaving a lot of wasted wood. That's the genius in Chuck Passaro's edge bending technique described in his great videos on the subject. Even with Chuck's method, though, some planks are going to require their own unique shape.
 
The smaller the boat, the more the plank shape differences are exaggerated. The below illustration shows the plank shapes needed to plank the hull illustrated. Note that the sheer plank shape colored white is actually wider at its ends than at its middle. In your planking job, the lack of the same sort of greater width at the stem rabet created a cumulative deficit in plank width which eventually created the upwards "hook" that became greater than you could bend your strip wood to accommodate. Trying to continue to hang 4mm wide planks in that rabet would only increase the deficit. (See the drawing of the period wooden hull planking below to see how the old-time plankers solved the problem you've got now.)
 

 
On a large wooden ship, the planking curves are not as radical, but do require curves to accommodate the shape of the hull just the same. In large construction, owing to the natural limitations of available plank stock width, "hooked," "doubler," or "stealer" planks are used to plank wider spaces than the available stock permits being gotten out of a single flitch. If a model is to show the plank seams, it must be planked as was its prototype. (Of course, if the plank seams are to be filled and the hull sanded fair and painted, it doesn't matter what the planking run looks like.) Look carefully at the plank seams in the bow and stern quarter of the below illustration to see the use of "hooked," "doubler," or "stealer" planks. (There's a larger picture and good planking instructions in the attached link.)

Don't let this discourage you. Kit manufacturers have been frustrating modelers with strip wood "planking" since kits were invented.  
 
 

There isn't any such thing as a "slight clinker effect." Plank is either hung "carvel" or "clinker" (AKA "lapstrake.") You did well to follow your instincts when planking and taper your planks. In fact, your intuitive solution is quite close to the actual practice, determining the width of the plank at the frame at the greatest beam and then the proportionate width of each plank at every other frame, which will give you the shape of each plank when the dimensions are laid out and a batten is sprung between the points so generated. 
 
If a hull is to be carvel planked, the edges of the planks are butted against each other and the hull is "faired," being planed and sanded to a fair shape so that a perfectly smooth hull results. A carvel planked hull is caulked with oakum and/or cotton driven between the plank edges so that the swelling of the planks against the caulking produces the necessary watertightness.) If a hull is to be clinker built, the planks are cut wider so that their edges overlap the adjacent plank, with the overlapping edges planed to a bevel which permits to overlapping planks to be riveted together, pulling the faying surface tightly together. (In this method, the swelling of the lapped plank faces provides the watertightness.) A clinker planked hull will have "gains" cut in lts plank ends so that the overlap transitions to a flat surface at the stem (and sometimes to some degree at the stern.). These gains are sloping rabets that reduce the thickness of the plank at the end overlap.
 
"Strip planking" is a relatively new technique made possible by epoxy adhesive technology. In this method, "strips" generally as wide as they are thick, are "stacked" up and glued with epoxy adhesive, then sheathed in fabric and resin. They are a form of monocoque construction, without frames. They can be quite attractive, but are not historically correct as far as their construction goes.
 
Google "Whitehall pulling boat" images and you'll see the range of "Whitehall" styles planked both types. Some examples are below.
 
Your kit apparently was designed to be simply "strip planked" (after a fashion) and finished to appear as a carvel planked example of the type. A clinker planked Whitehall at the scale you are working with would be a much more involved planking exercise than would be a "carvel-looking" hull. I would suggest you finish the hull smooth and painted inside and out so that it appears to be a carvel planked hull. It will not appear correct if it has "a slight clinker effect."
 
John Gardner's book Building Classic Small Craft, mentioned above, is an excellent resource for anyone building models of small craft. Indeed, with that book, one can spend a lot of time building many classic small boats without the need of kits at all.
 
A carvel planked Whitehall type pulling boat. Note that the hull is smooth inside and out.

 
An example of a couple of clinker planked pulling boats. Note the "gains" at the plank ends and the number of planks used.  Note that the plank overlaps are visible both outboard and inboard with the sawn frames sometimes "jogged" with notches so the plank lies flat on the plank face and sometimes not, those frames being steamed.

Nicely done and in record time! Now on to the next one... a scratch-build? Something from one of John Gardner's small craft building books? It's just my opinion, I think there is an overabundance of large Seventeenth and Eighteenth century ships of the line models and a dearth of simple small working craft models in this world. The small craft models look a lot better on a home bookshelf, as well. You will build better models in the future as your skills develop, as have we all to one degree or another, but this one will always have a special place in your heart, I'm sure.

Exactly. In fact, not even a "non-standard spelling," since there was no such thing as "standard spelling" back then! They just spelled phonetically and the word was "sounded out" by the reader. There were some efforts to standardize spelling prior to the 15th century, but standardized spelling didn't really start to catch on until the printing press became common. Manuscript writers continued with the phonetic spelling method for quite some time after. 

Fiddling with the galley cabinets today.

I have just used a common modeling knife and lightly scraped with the blade perpendicular to the surface. Just go slow and be careful to nhit only the high spots along the edge of the paint.

One job in a work house (a residence of last resort for the destitute) was to pick apart old rope for the fibers.  'Guess there was always a market for inferior (thus cheaper) oakum.  Note that the specification for the better stuff implies that the cheaper stuff was in use as well.  Hmmm, just as there are cheaper brands of paint (one often gets one what pays for, as the cheaper ceiling paint I used once was so bad I had to paint over it with more expensive quality paint).  
 
  There was a story about a painter who 'stretched' white latex paint by adding some water while painting a Church steeple.  When done, there were dark clouds and lightning as a furious rainstorm washed off most of what had been applied to the steeple ... and a voice from above was heard to say, "Repaint, and thin no more !"

I agree with Bob; an archaic non-standard spelling of 'tow'. And decaid is 'decayed' or worn out.

I wouldn't bet on it not being noticeable, particularly when the rest of the furniture is installed. 34 inches is the rule of thumb because when a boat heels under sail, the sink has to be at least that height to be useable when the sink is on the leeward side. Many galleys have "butt belts" the user can employ to strap themselves in or even bars that drop in behind the user that can be used as a seat or to brace against in a seaway. A sink that much lower would be noticed by an experienced seaman. It might not be that big of a deal in an RV that sits level, but not in a boat that may be sailing on her ear half the time.
 
Additionally, it looks like the sink is going to be below the waterline even at 34 inches and so it needs all the height it can get to make space for the sink drain elbow, hand pump, and the attendant plumbing with an anti-siphon loop and check valve.
 
I wouldn't have bothered to comment on something I realize many would think was picky, but this model has been so perfectly done, I, for one at least, would hate to see a compromise like this one, even if you had to look inside to see it.  
 
That said, I trust Michael's impeccable judgment in the matter.

A sink that much lower would be noticed by an experienced seaman. It might not be that big of a deal in an RV that sits level, but not in a boat that may be sailing on her ear half the time.
 
Additionally, it looks like the sink is going to be below the waterline even at 34 inches and so it needs all the height it can get to make space for the sink drain elbow, hand pump, and the attendant plumbing with an anti-siphon loop and check valve.
 
I wouldn't have bothered to comment on something I realize many would think was picky, but this model has been so perfectly done, I, for one at least, would hate to see a compromise like this one, even if you had to look inside to see it.  
 
That said, I trust Michael's impeccable judgment in the matter.

"Tow" is "short and coarse fibers of little value separated from the longer and more valuable fibers through hackling in the manufacture of rope. Tow is occasionally used in the manufacture of inferior qualities of rope." (International Maritime Dictionary, rene de Kerchove, 2nd Edition, Van Nostrand and Reinhold Co. 1961, Litton Educational Publishing]
 
"Tow" is also the short bits of fiber that break off of natural fiber rope, particularly hemp and sisal ("Manila") rope. On a large square-rigger, a lot of tow would find its way to the deck and collect in wet piles and muck things up. Hence the bosun's call, "Sweepers, man your brooms. Clean sweep down fore and aft." Another general meaning of "tow" is simply "worn out rope."
 
"Tow" was sometimes collected and saved for use in canvas pockets for padding of various sorts in rigging and so on, and for caulking material when mixed with tar to make oakum. Worn out or rotten line was often recycled into oakum as well. Quality oakum, however, was made not from lengths of worn-out line or "tow," but from new, long hemp strands. The highest quality new hemp line or oakum is made from the strong fibers from center of the stalks of the cannabis plant, which are whitish in color. (Oakum used by plumbers to caulk iron pipe joints is usually made from tarred jute or burlap.)
 
"Fibers and flyings" are what fill the air in a textile mill or rope walk and if you've ever been in a running textile mill, you will know that there is a huge cloud of fibers, little bits and pieces of broken fiber and dust, and "flyings" which are longer thin threads thrown off in the milling or spinning process, which must be continually cleaned up as they pose a large fire hazard. "Flyings" from the mills and ropewalks were used to make high quality oakum. 
 
Oakum is made by taking long fibers soaked in thick pine tar and simply twisting and rolling them into "ropes." The caulker has to prepare the oakum by unraveling lengths of the loosely twisted fiber from the loose ball (or "bale") of oakum and rolling the pine tar-soaked strands back and forth between the palm of his hand and the top of his thigh. (If you see a guy in the boatyard with his pants covered with tar on the front of his upper leg, he's a caulker! )
 
So, "The white ocham to be from flying & not from ground toes or decaid White ropes." means, "The white oakum specified here is to be made from mill flyings of the top-quality virgin white fiber of the plant and not from ground up tow or recycled rotten white hemp rope."
 
Quality oakum will result in a longer-lasting caulking job. Using old, weak fiber from worn out, rotten, or "decaid" rope will rot and decay in short order. The Admiralty wanted to use "the good stuff" because they didn't want to have to recaulk in short order because the stuff used was rotten to begin with.
