    The XXI build has a lot of really nice photo etched brass work! The build would not be complete without it.

    I personally feel it would be a shame to paint over the brass! This build by the way is going to be just a static display. So my though is to finish the boat in a scale color and then apply the etched brass after and leave it in its natural form.

    Now I have another question: Does anyone know of a water based adhesive that will work with brass and PLA? I am now fighting a real allergic reaction to all CA adhesives! I guess wearing a mask will help, but having it in my building environment now will be an issue. All this gluing and using CA has finally caught up with me!

    If you look closely, you can see the screws and nuts that I am using on this build. As you can tell by the upper decking, there will be a lot of brass photo etching to install! If you have followed this build, you have seen all the photos and input that David M. has posted, and it will be a GREAT help for sure!! Thanking you again David!

    LOL. This round-eye learned these tricks from everyone on this rock of ours who made the effort to pass on what they learned. And that's all I'm doing -- passing it on.

    what is the material you used for the rail alignment jig on the Type IX? it looks like Renshape, but I was not aware that it would withstand the heat.
    Thanks
    I use both the dense and lightweight RenShape for soldering jigs. Both can take the heat of the operation. An important consideration is to dig out a cavity under each portion of the jig under which a solder joint will be made -- this to limit the possibility of off-gassed polyurethane products from contaminating the union. The lightweight RenShape is easy to shape and accepts securing pins with little argument. The dense stuff, not so much.

    I wonder if the design of the one I did has anything to do with the changes!? The files I purchased came with a complete set of brass photo etchings to complete the model. If you look at the photos of the kit you can see just how important the etching is to the complete build.

    Not everyone is into installing or using photo etching, so the next designs might do away with the brass work! It's a great looking boat, and if he brings it back with a different build design it should do well. And having files for a 1:48 scale is even better!

    I know that it should be cleaned with laquer thinner, and then a bath in some sort of acid! I am thinking vinegar would do the job!? I have heard that some like to use a more aggressive acid! Any input would be appreciated! Thank you!

    This is some of the brass etching that came with the kit.

    I am going to put some time into the Nautilus, and then I will do some more on the Type XXl! I am going to do some engineering work on the hull design in order to install a WTC! Not sure how I will do this, but with some work I am sure I can achieve what I need!

    It has been sometime since I started building the 1:72 scale Type XXII.

    Just to refresh where I left off on this build, you can see by the photos that I have not put it together yet. This Type XXII came as a 3D printed set of files that I purchased from Nautilus Drydocks. (No longer available, not sure why?) I am building this boat as a static model and not powered. I am going to put it together as per the instruction's and using the nuts and screws to fasten the 10 sections together. A total of 60 fasteners.

    I am also going to use the brass etching that came with the kit as well.

    OK! I have tons of stranded copper wire from my Shortwave Radio days and building antennas and Radios!

    David! Thank you again for your time! I have downloaded all your articles and photos on this very subject! I will use them to the fullest extent! I will post up photos as progress warrants! I am really looking forward to this new concept of the hobby! And for me to have the master builder (you) in my life, just makes it so much more meaningful for me to be learning from the BEST!

    Thank you again David for sharing your knowledge, and most of all your willingness to help!!!

    Two questions to start? What size and where did you get the brass? I did find 1/16" on amazon!
