    Making alterations and major fixes - this gets you into some aspects of scratch building.  As long as your course is tending to the "dark side" you could consider a visit to a hardwood dealer and get some veneer of closed pore wood species and plank the hull instead of painting it. Get a light species like Maple and actually plank the deck.  With veneer, you can use a #11 blade and a steel straight edge to cut out the planks - no expensive tools needed.

    If you trace the outline of the keel- stem- sternpost assembly and rubber cement it to thick  cardboard or a piece of corrugated box - trim it to the inside dimension - fit it to the hull:
     
    the hull is longer - trim the skeg back and it may be the 1/8" needed.
    the hull is correct, just too thin --  glue a temporary sternpost that is the correct size - use liquid hide glue-  fill out the skeg with a filler like Bondo and fair the hull.   Once the shape matches the templates, the temp post can be removed - heat gun/hair dryer and water or rubbing alcohol that is 91% ethanol will undo the hide glue.  The real unmarred post can now be fitted.

    If the African wood produces more problems than it is worth, you might consider a different tack.
    Your original complaint is rooted in your choice to use a stain.  Stain is essentially a paint - it covers.
    You could get to your original goal by using a wood dye.
    Aniline wood dyes come in two flavors - water base ( aqueous ) and alcohol based.
    The aqueous soaks in more than the alcohol and may be clearer when finished. The cost is that it takes
    longer to dry and the first application tends to raise the grain of the wood.  The fix is to either fine sand
    after the first application and then do another - which may produce an inconsistent finish -  or treat the wood
    with water or water with 1:10 PVA added to lock down the fibers - sand after and then apply the dye.
    Dyes come in several primary colors as well as various wood shades.  White is the one that will require a paint.

    If it is Mahogany as the shade you like, take a look at Black Cherry.  It is closed pore and the grain scales better than genuine Mahogany and much better than Lauan and other substitutes.  Woodcraft has a 3 sq ft pack for $10 - although they do not provide the thickness.  Since Black Cherry is not expensive in the States, it may be thicker than the exotic species.  Generally, the characteristic that makes exotic woods popular is contrary to what we want - the grain.
    You could also consider Birch or Beech and use a aqueous analine dye to get your desired color.
    As for caulking - with scale effect - less is better.  consider Walnut as a color rather than black  and for thickness  scale /2 .

    If you use John's method -  the amount of distortion that your scanner introduces should probably be determined and corrected.
    I used a transparent 15 cm ruler as a source and printed the scan of it.  When matched to the original the scan has to be
    X & Y scaled up by 102.5% to get the print to match the original.

    Jaager got a reaction from mtaylor in New to ship modelling, what wood to use?   
    No, not Navy, although they are close neighbors now.  I was PHS. 
    Two LSD are in, but parked around the corner and a container ship
    whose engine seems to have not worked for at least 10 years and I guess 
    belongs to the Reserves is hiding the Cyclones and and experimental
    stealth twin hull vessels.
     
    So, you have whatever is being substituted for White Pine these days,
    or may be Eastern White Pine.
     
    With a hardwood with a Janka hardness rating closer to 1000, the sharp edges stay
    more crisp and do not ding as easily.

    White Pine is a traditional species for a solid hull.   The  pine that you are getting is probably from a tree farm, a species or hybrid species chosen for rapid growth and a straight trunk.  I would guess wide grain that is high contrast.  It could also have gummy sap.  Not a particularly good choice for model making.
    Yellow Poplar is a good choice.  It is a bit too soft for POF hull construction for my taste, but it will do the job well.  With the proper cutting tools, Yellow Poplar should work well.  I used it for a plug to make a 1840 1st launch and it cut and sanded well.  It carves easily - you just need a sharp edge and fine touch to keep from removing more than intended.  The only real downside is the green color if it is left natural and clear finished.
    You do not identify your location - if you are in North America, see if there is a hardwood vendor in your area.  Hard Maple and Black Cherry are at the low end of cost for a domestic, and are about as good as it gets for our use.

    Jaager got a reaction from mtaylor in gluing pre-stained wood   
    A wood dye should have no effect on a PVA bond.  A stain is a surface coat - similar to paint - it would depend on the specific product  - but there is a chance that a bond may fail because the stain seals the wood pores and blocks penetration of the glue polymers.
     
    Your best bet is to do the experiment on scrap wood and determine the effect.  The stain manufacturer could have altered the formulation and if someone had an answer from years ago, it may not apply to your situation.

    Weldbond is a PVA adhesive.  It is pH 4.5 instead of pH 3.0 for Titebond II so it is 15 times less acidic.
    Not a significant factor for wood to wood,  but possibly makes a difference in longevity with paper or natural fibers
    : linen, cotton.
