    Most varnish products will probably not play nice with most glues.
    The glue will "bond" to the finish rather than the wood.  With no
    pores there is no penetration so any bonding will be electrostatic
    rather than mechanical.
     
    Traditional varnish is boiled linseed oil "cooked" with shellac - organic solvents.
    These days polyurethane seems to be more popular and there are
    water based varieties.  It is a synthetic plastic.
     
    If you are doing an upscale modern yacht, varnished decks may be appropriate.
    You wear no scuff deck shoes to walk on them.
    For most other classes of wooden ships, a slick varnished deck would be really
    dangerous for the crew. 
     
    Because of scale effect, a flat or egg shell finish even for high gloss prototypes -
    or at most matte..
    You might consider super blonde shellac at half strength ( 5%) * and rub it down
    with 0000 steel wool or a Scotch Brite pad.  In any case, if you intend to apply a 
    finish before adding and gluing down additional components - it would be wise to
    occlude the glue sites with painters tape or masking tape.
     
    *  orange shellac is full strength at 20 lb cut ( ~ 20% solution in methanol,
    ethanol (denatured) or ( Pharmco grain - 95% - if you do not mind paying the taxes),
    or anhydrous isopropyl.
    It will darken the wood.
     
    super blonde shellac is a very light amber.  The purification process removes components
    that help solubilize it - so - full strength is 10 lb cut ( ~10%).  Primer or 1st coat = 5%.
     
    There is a bit clearer grade: plantina shellac flakes - but it is not that lighter and costs about
    twice what super blonde costs.

    This I did using a Byrnes rope walk.  I will have to play with the setup
    to get the warps more acute but that should not affect these data significantly.

    The diameter was measured using a lacquered dowel and counting the
    closely packed rotations in an inch.

    There are also draw tongs.  They are for gripping wire, but work with
    bamboo - if pieces of sandpaper are used as an interface to grip and
    you do not squeeze too hard.

    It may not be a significant level of energy with LED lighting or florescent either, but
    the way greenhouse effect works is that  some visible energy photons will degrade
    to IR when they strike something inside the chamber and the transparent material at
    visible will reflect IR and keep it inside.  Granted, most will stay in the visible spectrum
    and reflect back out. - We would be able to see what was inside otherwise. - But while
    a UV filter may protect against the chemical reactions that UV produces, I doubt that
    it would negate a heat build up in an efficiently sealed chamber.
     
    With your room lighting, the lack of heat with LED even given your high light level, shows
    just how inefficient and IR heavy incandescent lighting is.  However, given where you
    live, there may be parts of the year where you might miss having a little extra IR.
     
    When I was using  300 W of bulbs to heat a homemade kiln 24/7, I did have a measurable 
    increase in my electric bill.
    Our philosophy seems to be in tune, I also have a tendency to over engineer my designs.

    I have thought about the same ideas.
    For the gas to remain, the container would have to be
    air tight.  The walls are transparent, so light can enter.
    Being totally sealed, there is a possibility of an extreme
    greenhouse effect and the container becoming oven-like.
    There is a problem with this - even in a not  totally air tight situation.
     
    Joel has it correct - vent holes for circulation for both temp and
    removal of outgassed compounds.  PVA wood glue would probably
    release acetic acid.
    My thinking is vent openings at the top ( for temp ) and probably
    also bottom for circulation.  The trick would be to keep dust out.
     
    Too dry - the wood may check and split over time.
     
    .The museum standards for ship models are probably intended to
    preserve a model for as long as is practical - by using materials that 
    last to begin with.

    The linen supplier twists up the fibers into yarn.
    This is sold as LEA - which is essentially an obsolete measurement - it has been replaced -
    but I have not mentally absorbed it. Since I have obtained about as much and as wide a 
    variety of linen yarn as is obtainable now, I don't need to deal with the change.
    And yes,  with LEA - the larger the number - the smaller the yarn.
     
     
    From our perspective  the hope would be that  70.2  LEA yarn would be 2 lines with a final size of 70,
    but alas -  what it means is
    Two 70 LEA yarns twisted together and sold as a loosely twisted  thread..
     
    If unraveled  it would be   two 70 LEA yarns - not two 140 LEA - which would be nice for us
    except -  twisting up the 62 LEA is difficult - it breaks easily - so that may be the practical limit.
     
    I finally got why the old guys favored linen - the linen wrapping on Egyptian mummies is still largely intact.
    It does not readily oxidize.
