My 3D Printed HL-Hunley Build

[Groot689]

Great start! Delighted to see someone building this point especially from 3D files! Looking really good.

The printing work is moving along on the Hunley!



As you can see by the photo, the detail on this boat is exceptional! Looking forward to the print completion!

Yes, but a much simpler mechanism -- you will only be pitching the shaft, the big rudder needs no help from yawing the shaft.

OK! Thank you David! I am sure that I will summon for future help on this project! Thanks for being there for us!

David,

Thank you for your help on this boat! I am very happy that you feel the MSD that you gave me will work. I have been waiting for a special sub that I could use it in! I like the fact that the HL-Hunley has a very unique design and history to it. Very fitting to use a very special MSD! Thank you again David.

David! The gimbal control for the propeller! Will that be a similar control system that I will be using on the Disney Nautilus? If I understand you correctly I need to be able to pitch the propeller up and down?

Other than that MSD having much more ballast tank than you need for the HUNLEY, I don't see any problem using it. As to the model itself, I recommend you gimbal the propeller in pitch as without a positive means of pitch control this submarine is a ***** to maneuver underwater. So, one channel for the bow planes, good for fine depth control; one channel for the ballast sub-system; one channel for the rudder; one channel for the ESC; and one channel for the gimbal.

These clips from the SubRegatta 96 event shows the HUNLEY model I contributed some work to in and out of the water: https://youtu.be/_C1O9X6m3Ag 29:15, 50:50, and 32:15

I am going to try and use the 2.5" SD that I received from David M. not to long ago! There really has to be a way to make it work in the Hunley! This SD is very special to me!!





I will be using the VEX transmitter with a 4 channel receiver. I also purchased this system from Nautilus Drydocks some time ago

Another Build!!

I have decided to go with the HL-Hunley build! I ordered the 3D print files form Bob (Nautilus Drydocks) today, and I already have my Dremel 3D40 at work!



I Already have my Dremel 3D40 hard at work on the files! Looking really good at this point. I am using Solutech Plus White PLA! I have printed out 4 submarines using this material and I have not had any issues with the PLA. All 4 subs have been in the water (15 min. at a time) But I make sure to keep them out of heat the after each run.



I am going to work on both my 1:77 scale Disney Nautilus and the HL-Hunley at the same time!
