    Great to see the keel laying Joss; but I seem to have missed the ceremony   Great process that results in very clean well mating joints.
     
    cheers

    Congratulations on laying the keel!
     
    Mark: we know that each scarph joint is good practice for the next one... and the next....

    Good Evening Matrim;
     
    That's looking like a good start; only another ten zillion scarph joints to go! 
     
    All the best,

    Time for a ramble and then an update..Years ago Henry Ford commented on failure
     
     
    which is a wonderful way to approach things I think and is certainly something I use a lot in modelling. The relevance here is that I started on my keel pieces and used the approach I detailed (in considerable detail) around page 5 of this log ( urk 5 years ago).
     
    Anyway I cut some joints and wasn't happy with them. Two things in particular irked me and these are admittedly both correctable. Firstly using the scroll saw to cut the shoulder tended to produce a slightly angled cut that became more obvious once the joint was made (this can be expected as the Scroll saw will cut faster as it initially contacts but the later cuts meet more resistance and the blades are thin enough that they can bend). The solution here is either a thicker blade or a slower cut with a faster saw speed. The other was that post table saw cut (close.) to the diagonal line the joint still needed lots of hand work and it proved surprisingly easy to over work it and go to deep etc. Either way I was not pleased.
     
    After considering the problem I decided to try two different approaches. For the initial shoulder cut the table saw would be an adequate replacement. It can cut to a specific depth, utterly straight thus eliminating any bend. For the diagonal though I had to think of other options and in the end moved to use one of my favourite power tools - my Sherline mill specifically with an end mill. I had used this in the previous build for the complex joint at the end but that was at right angles and this most certainly was not. The main issue was that even if I managed to replicate the exact angle of the cut over every cut even a slight over cut would result in different angles and bad joints.
     
    My way of compensating was as follows (and I may still change this as I am (frankly) still tempted to cut all the joints with the same angle).
     
    Anyway. I used one of the better previous pieces as a base line and secured that in a vice. I then put the next piece into the joint but the wrong way round. This way the bits to be removed would stick up and I could then mill them out. The advantages here are that as long as each joint matches if I over cut one then the next will automatically be undercut and vice versa and 'should' be a good join. At least to acceptable tolerances.
     
    Since this makes little sense lets cut to lots of pictures. Please note that the mill shots are of the initial pieces cut against a set angle, after these are cut following joints are made with the joint it will be used with.
     
    Here is the initial method of securing the keep piece and what the mill is cutting against. The key point is not to drop lower than the table saw cut (which can be clearly seen to the left). The mill has several methods of ensuring accuracy across multiple dimensions so its a matter of how its approached as opposed to a specific way of doing so.
     

     
    Next up we have shot of the joint once it is complete. 
     

     
    since you still have to be careful near the shoulder itself it may still require some very minor manual touching up.
     
    Here is a photo of the simple keel pieces 'complete'. You will notice piece 1 is considerably oversized. This is so that once gluing is complete I can cut that to the exact keel length and thus avoid any incremental sizing issues that might have arisen in either direction.
     

     
    Another of the pieces on their sides with my simplistic joint numbering system
     

     
    As a rough sizing attempt I laid it on the full size plan
     

     
    Finally some detail of the joints
     

     

     
    Next up I have to work on the complex joint at keel piece 6 but I am expecting to redo this for two reasons. The first is I don't think I cut enough blanks (I have 4 for the box joint and they are oversized so in case of disaster can shorten and restart) but more importantly I think I need more fat on these pieces for thicknessing to the correct size post gluing. This 'may' not be necessary but for the moment I am treating as a blind test run so see what other potential improvements/technique adjustments can be planned. I also want to re-look at that joint in turbocad. I did design it with the main joint at an angle but in the original version I kept it at right angles to simplify it. I'm not currently sure which approach to take.
     
    Anyway thanks for reading!

    Here is the initial method of securing the keep piece and what the mill is cutting against. The key point is not to drop lower than the table saw cut (which can be clearly seen to the left). The mill has several methods of ensuring accuracy across multiple dimensions so its a matter of how its approached as opposed to a specific way of doing so.
     

     
    Next up we have shot of the joint once it is complete. 
     

     
    since you still have to be careful near the shoulder itself it may still require some very minor manual touching up.
     
    Here is a photo of the simple keel pieces 'complete'. You will notice piece 1 is considerably oversized. This is so that once gluing is complete I can cut that to the exact keel length and thus avoid any incremental sizing issues that might have arisen in either direction.

    Finally some detail of the joints
     

     

     
    Next up I have to work on the complex joint at keel piece 6 but I am expecting to redo this for two reasons. The first is I don't think I cut enough blanks (I have 4 for the box joint and they are oversized so in case of disaster can shorten and restart) but more importantly I think I need more fat on these pieces for thicknessing to the correct size post gluing. This 'may' not be necessary but for the moment I am treating as a blind test run so see what other potential improvements/technique adjustments can be planned. I also want to re-look at that joint in turbocad. I did design it with the main joint at an angle but in the original version I kept it at right angles to simplify it. I'm not currently sure which approach to take.
     
    Anyway thanks for reading!

    which is a wonderful way to approach things I think and is certainly something I use a lot in modelling. The relevance here is that I started on my keel pieces and used the approach I detailed (in considerable detail) around page 5 of this log ( urk 5 years ago).
     
    Anyway I cut some joints and wasn't happy with them. Two things in particular irked me and these are admittedly both correctable. Firstly using the scroll saw to cut the shoulder tended to produce a slightly angled cut that became more obvious once the joint was made (this can be expected as the Scroll saw will cut faster as it initially contacts but the later cuts meet more resistance and the blades are thin enough that they can bend). The solution here is either a thicker blade or a slower cut with a faster saw speed. The other was that post table saw cut (close.) to the diagonal line the joint still needed lots of hand work and it proved surprisingly easy to over work it and go to deep etc. Either way I was not pleased.
     
    After considering the problem I decided to try two different approaches. For the initial shoulder cut the table saw would be an adequate replacement. It can cut to a specific depth, utterly straight thus eliminating any bend. For the diagonal though I had to think of other options and in the end moved to use one of my favourite power tools - my Sherline mill specifically with an end mill. I had used this in the previous build for the complex joint at the end but that was at right angles and this most certainly was not. The main issue was that even if I managed to replicate the exact angle of the cut over every cut even a slight over cut would result in different angles and bad joints.
     
    My way of compensating was as follows (and I may still change this as I am (frankly) still tempted to cut all the joints with the same angle).
     
    Anyway. I used one of the better previous pieces as a base line and secured that in a vice. I then put the next piece into the joint but the wrong way round. This way the bits to be removed would stick up and I could then mill them out. The advantages here are that as long as each joint matches if I over cut one then the next will automatically be undercut and vice versa and 'should' be a good join. At least to acceptable tolerances.

    You’ll find all across this forum people rave about the Byrnes saw, I like everyone else love mine.  I use it all the time along with my Byrnes Sander.  I haven’t sprung for the thickness sander yet, but based on the seemingly shortage of quality strip wood it may be next.

    I have a Byrnes saw and can do a reasonable job of ripping my own, in fact I did for my current model since I couldn’t find anything and still had a few billets from Jeff. It’s just that I prefer not to, I don’t do it enough to be good at it and I don’t have the proper ventilation to rip something like ebony. 
     
    Even with that, I’m still looking for a source for quality woods in sheets in 3-5mm thicknesses. I’ll try some of the sites listed.  I do miss Hobby Mill, didn’t realize how good I had it with Jeff.

    Excellent advice, Bob.  I would add Rule 4: Rehearse the cut. i.e. without the saw running push the work through exactly as you plan to do.  This enables you to answer questions like - where will my hands be? Is there any obstruction on the exit side? etc.

    I often use a #2 pencil with an eraser as a push stick. The eraser side down on the wood. I also make up push sticks as I go. It only takes a few seconds. Rule One: Never reach over a table saw blade. Rule Two: Never stand in line with the blade. (Avoid getting hit by a kick-back.) Rule Three: Always use a push stick when ripping.

    First read the instructions that came with the saw. (I'm not saying this to be snarky. You'd be amazed how many people in this world never read the instructions... including my Dearly Beloved.) The instructions should show you how to set up your saw. You will probably want to move the fence to the other side of the blade and you'll want to find a place to keep your miter gauge until you are ready to use it besides where you've got it in the photo. 
     
    Then, start with the YouTube video below and then keep watching the basic full-size table saw operation videos on this page: https://www.youtube.com/results?search_query=how+to+use+a+table+saw  The operation of the Byrnes saw is the same as that for a full-size table saw. Pay close attention to the safe operation rules. The Byrnes Saw is small and quiet, but no less worthy of respect than a full-size table saw. It will injure in all the same ways, albeit perhaps on a smaller scale. 
     
    To get the most from your saw, you will probably want to also acquire the factory-made cross-cutting sled that will make short repetitive cross cuts easily and with extreme accuracy. 
     
    This advice may seem a bit simplistic, but a good command of the basics will get you off on the right foot.

    Hi all! So I now have a Byrnes saw and have very little idea on how to use it. Yay! The ultimate goal is to make fine precise wood strips 1mm by 1mm thick so the question is what is the process needed to get to such a specific and small wood strip? Like how should the machine be set up for something so small and precise? I'm open to suggestions and words of wisdom and experience resources to watch or read if i need a sliding tray, ive already ordered a calibre. Ill add pics of what I currently have (blades and otherwise) shortly.

    Personally, I would use a clear varnish or sanding filler (both organic solvent-based !) to stiffen the material - a dab of thinner allows you to re-arrange the sail even after the varnish has dried. CA or acrylics cannot be easily softened without destroying everything.
     
    Also at this small scale, real cloth is most likely too thick and coarse. For set sails the lightest silk-span might do, but for clewed-up or furled sails tissue paper is a better option. In the case of furled sails, you may also find that a full-size sail will result in too much sail on the yard, just shorten it a bit until the amount of sail looks right - this is because even tissue is way over-scale.

    A small update on the furled sails.
    Attempt 1 (and 2) with different paper tissue and CA glue. Wasn't what it was supposed to be.
    I got good results with it in military modeling, but for furled sails, unsuitable.
    Also discovered that the brown color of the yards did not match this model, so they are painted black now.

     
    Attempt 3
    sails sewn from cloth.
    1 test model done.  This attempt has worked out reasonably well, but not quite what it should be.
    To be continued, thanks for following.

    Here we go again.
    The Bounty build is restarted, If everything goes according to plan, she will be ready this winter
    The yards are painted. And now i can start with the rigging.
    I had the idea of adding sails. But since my base plate looks like the bottom of some kind of dry dock this is not really appropriate.
    A ship with full sails in dry dock ... not good. So no sails or maybe furled sails.

    Greetings! When working on kits I tended to paint once the part was complete (so the wales when the wales done) but not wait until the end as rigging etc gets in the way.
     
    On my first kit i did this then covered the entire model in talcum powder in an erroneous attempt to mark the water line. Then I had to paint it again plus wash out bits that should not be painted. (Did look good as a 'ghost' ship though...)
