  1. Long time no update but I haven't been idle..  Sidetracked on a couple of other projects, and being less satisfied with how the hull is shaping up.  I will have more on that later.

     

    They say " The Devil is in The Details ", and boy, is it.  In any event it all has to be done sooner or later.

    I discussed the design of the quarterdeck bulkhead a while back.  As discussed, the drawing in the MS plans by Campbell is his ( expert? ) interpretation, and essentially duplicated by Hahn and Mamoli.  No expert here, but I find the windows in the center panels and not the doors a bit incongruous.  I made a back piece with etching on it and a frame to fit over the back, in which I was thinking about inserting panels and doors.

    Going forward with a prototype, I decided to try some laser assisted carpentry.  I don't want to paint, but going with bare wood calls for careful planning to avoid wood grain going in one direction in a continuous pattern, and I also want to avoid a strong variation in wood color across the whole assembly.  I am also learning some important considerations when doing this with a laser.  The arrow points to where the middle column should fit, and there is about a 1mm gap.  What I didn't account for is what I now call " Kerf Creeping ".  The kerf of my laser is less than .5mm and there is a kerf offset built into the software to account for the kerf, but it takes some tweaking, as well as optimizing the focus and keeping the lens clean.  Considering I had 12 vertical joints going from left to right, and a gap of ~1mm, that means my kerf was too big by about .08 mm.  So, I am going to have to adjust for that next go around.  It might just be a matter of cleaning the Laser lens.

    I didn't spend a lot of time cleaning off the laser char, and I think doing more of that will make for a better look.  I think the upper and lower framing might look better if there is one continuous piece/ beam. 

    I'm also looking forward to see how Chuck approaches the bulkhead with his Speedwell build.  I'm sure I will get some ideas for refining my methods.

    at what point is the content parsed into “pages’ - does the tool do this automatically

    Yes

    If you add several pictures at once, can you go back and add text and/or caption them or do you have to do this for each picture as it’s being added?

    After you add the pictures, you can place the cursor to the right of a picture and press 'enter.  You may then add text under the picture.

  3. I'm reading through the book " Legacy of a Ship Model " by Rob Napier .

    Something I noticed, and have seen on other contemporary models, is that the deadeyes are almost spherical  .

    Does anyone know if this was just a modeling convention, or if actual practice ever consisted of deadeyes shaped like this?

    I don't know the purpose of this spherical assembly in the pump,

    You may have this picture but it shows a little more detail.

    It looks like some copper vessels that allowed for a larger volume of liquid to be discharged as opposed to just the diameter of the main pump body.

    Another view.  This appears to be a different set of pumps consisting of two pumps.

  5. Another quick little job.

    I didn't set this up as tight as I could have.  I wasn't concerned with small deviations, but maybe should have been.

    These pieces are the tentative quoins for my tentative Rattlesnake cannon.  I needed a hole to insert the quoin handle.

    With hind sight, a little jig to do them securely one at a time, would give me more precision..   Next time.

    Still in prototyping phase.  Experimenting with mahogany for some contrast on the gun deck, as I have chose not to paint.

    I will probably go back and do a better job of centering the quoin handles, because it's one of those things I would lose sleep over.

     

    Anyway, just another sea trial for the drill press.  It is really up to the task, but I need to prep better.

  6. I did a little milling operation today.

    I'm working on some cannon for my Rattlesnake, and they require a lot of split rings and eyebolts.

    This method has been gleaned from a lot of discussion about making these things.  I would have to say Chuck Passaro is my primary instructor on this.

    I have wrapped some 24 gauge annealed steel wire around a #56 drill bit fixed in a dowel.

    All the X, Y and Z adjustments took a little doing and there were a few oopsies before I got it where I wanted it.

    The tool is a .009 separation disk.  Chuck P. says he has a saw he uses, but I have decided to go with this.  Anyone who uses these discs can attest to how fragile they are.  It's not unusual for me to break one just setting it up in the mandrel.   If this set-up were not tight, the disc would not make it through the job.  I can actually hear/feel a little click when one of the rings is cut through.

    This picture is toward the end of the operation.

    Here is the result.   The one with a circle around it snuck in from an earlier effort with a different method.

    The open rings close up almost flush with very little pressure.
