  1. Thanks for all the help!

    Applied much more glue this time, glue was pre-dried (small can left opened for 24hr).

    Looks much better, warping is minimal, and I used some extra clamps, stronger ones.

    As it turned out, the lamination was ok - no sign of gaps or warping anywhere when the frame is cut.

     

    Cut the test frame just to verify the process. It would not be installed on a model, the goal is only to practice.

    First question: what is the proper margin, how far should I cut from the lines? If I cut too far away - frames would be either fat, or there would be an enormous amount of sanding later on (and with too much sanding the final shape of a frame would not be close to a proper lines). If I cut too close - frames would be too small after sanding. What is the golden rule of thumb?

     

    Here is the side of a frame. Glue layer is slightly visible, but I guess that is expected? Or not?

    A lot of sanding and scraping to bring the frame down to desired 7.2mm thickness.

    Note to readers - avoid using a heavy grits, even if you need to remove a lot. Sanded with 60 grit and got some deep scratches, very hard to remove. Good that it is a test frame, would be quite sad otherwise :)

    And the end result is:

    When sanded with a fine grits (1200 => 2000), the colour difference between various part of the frame is striking. Not sure what to do with that.. Well, in the end it is not plastic, so it is quite expected from wood to have a different colour naturally :)

     

    Please post any critics, it is very important to get the technology right on a test frames. 

    I am posting detailed process pictures hoping that somebody will spot a mistakes and share a good advice before I will produce 40 frames using a wrong technology :)

  2. (carefully writing down the notes).

    Mark, thanks again for a step-by-step documentation of your build. It is very useful for a novice builders like me! :)

     

    However, just in case if you missed it before, is that an optical illusion or there is a small "pit" in the frame here? 

    post-5430-0-51666500-1410421433_thumb.png

     

    Or the frames would be significantly sanded anyway, so such small things should be ignored?

  3. Mark, Greg, thanks for comments!

     

    But there is one thing I do not understand. If the surface of blanks would be rough when gluing them together - that will increase the gap between the blanks, and will require to apply more glue, which will increase the wood warping.

    Or I simply need more clamps and higher pressure to prevent warping.. I'm already pre-drying the glue to reduce the moisture level.

    But if two very experienced builders recommend it - I should listen. Will sand the blanks with a low grit to get a rough surface, will see how it behaves.

  4. Started to make a frame blanks. Discovered that my table saw is not precise enough, but luckily frame blanks do not require a lot of precision.

     

    First - edge gluing on a flat surface, with a blueprint under the glass to make sure that everything is assembled correctly:

    Second - laminating. Many thanks to Mark for making a good thread where hidden traps of lamination are discussed. I used a thick plexiglass and a lot of clamps:

    post-5430-0-73594500-1410120813_thumb.jpg

     

    Even with a small layer of glue, that is pre-dried, wood warped a bit:

    post-5430-0-06496300-1410120873_thumb.jpg

     

    But after 10 hours it looks close to normal, no warping:

    post-5430-0-05042300-1410120913_thumb.jpg

     

    But I'm worried that there is a consistent small gap between the layers:

    post-5430-0-73356800-1410120957_thumb.jpg

     

    To reduce the gap, will need to apply more glue - but that will case even more warping.

    Or try to polish the surface of blanks even more before gluing (I sanded them with 240 and 380 grits)

     

    By the way, quality of wood for blanks is, khm, questionable. Width varies a lot (might be ok, it is just blanks, but makes it harder to cut with an accurate angle on a tablesaw). Thickness is also very random, will need a careful thickness sanding when frames would be cut. Colour of that swiss pear is also very different, from very pale to bright pink. The most strange thing is that all laser cut parts are much darker than planks for frame blanks, but they are expected to be same wood (swiss pear). Luckily, this time colour difference is actually good, I was worried that frames would be too dark. And having a darker keel and keelson might be ok. But it would be good to have a consistent colour of the wood inside one package.

     

    Plus a lot of planks have a pretty visible grey areas, around half of the planks are affected. Worried that they might be visible on a frames. Like this:

    I understand that it is perfectly natural for the wood, but that's the whole point of buying a milled wood for modelling - it should not have such imperfections... Or I might be just spoiled by a wood package from Hobbymill :)

  5. Finally finished most of the renovation works in the apartment, and here is my modelling corner! :)

    post-5430-0-86064300-1409866427_thumb.jpg

    All the tools are in a large drawer, only most popular ones are stored in the table itself.

    The band saw is hidden under the table, it would be rarely used.

    The drawing is a Cromwell plan from NMM, but it is purely for decoration - Hahn plans are much more detailed.

     

    Since my wife occupied another corner for her knitting stuff, it is a time to rename the "living room" into a "hobby room". But hey, isn't hobby a big part of our life? :)

    post-5430-0-47684400-1409866750_thumb.jpg

    (Yep, I know that furniture is quite not in same style, will slowly fix that over time)

     

     

    So now I can finally start cutting the frame blanks! Finally! Time to make a first bucket of sawdust :)

  6. Divarty, congratulations with a decision to redo the planking, I thnk that model is perfectly suitable for it.

    Have you considered a boxwood package from Hobbymill? A bit more expensive, but worth every penny. Planking with boxwood is such a pleasure comparing to basswood. I planked two models - Pinnace with bass, and Longboat with box - the difference is very big, boxwood planking is easier, more stable, etc.

    And just a mere fact that after initial sanding basswood planks from the kit are like twice thinner than boxwood ones from hobbymill. It means a lot!

    You can compare the photos in my logs (see links in the signature). Longboat planked with box is not sanded yet, and already looks much better than basswood after sanding!

     

    But beware: when you will try a booxwood package for longboat, you will never go back to inferior wood, and will end up paying quite a lot for a good one! :)

  7. Jud, you are right, it is a dark corner table :) Other setups will take too much space in a living room. And I can't afford an apartment with a dedicated hobby room. One day kid will grow up and move away... :)

    So the idea is to light that cave with a good lamp.

    Found some brand daylight, they say right things, but the website looks too much like a marketing blah blah. Gut feeling that they could just repackage some chinese lamps in a nice box.. Or I'm wrong?

  8. So conceptually I am looking for a bare lamp like this:

    post-5430-0-79110600-1408391052.jpg

     

    It would be mounted on top of that table, under the place where Pinnace stands on that photo:

    post-5430-0-74881900-1408391102_thumb.jpg

     

    Unfortunately most of such lamps are designed for kitchen and have a terrible light quality. And if you search for a separate light bulb to make this lamp by yourself - there are gazillion of different technologies :(

  9. Making a modelling corner in a new apartment, and want to do a proper light on my modelling table. No need for a table lamp, no mounts or clamps, I will integrate the lamp into the top part of a table itself.

    My table is in the living room, so the room is already light.

     

    However, need a guidance in what kind of a lamps are preferred..

    * No high frequency flickering like in a cheap fluorescent lamps. Lamp should not make eyes tired

    * Not too bright

    * Neutral spectrum and colour palette, when I look on a wood or paint, I want to see a real colour, without effects of the lighting

     

    Basically, it should be a pleasure for eyes and it should not skew the colours.

     

    Price range - I hope to be below $150.

     

    Would really appreciate any hints, what type of a lamp to use. I saw some professional jewellery lamps, but they are around $400, which is too expensive.
