My 3D Printed HL-Hunley Build

[Monahan Steam Models]

Moving right along! Good job. Can’t wait to see the results of your first splash tests. Keep the build updates coming.

Thank you sir! I sure will. Tomorrow will be the WTC test dip!!!

Today I finished up all the wiring. Motor, servos, ballast pump, ESC, battery, and the magnetic switch! I am using Deans Plugs on the 7.4 Volt wiring coming from the 2 cell 35C 2200 mAh Li-poly battery that I am using!

Rob, those cylinders are designed for 3S LiPos. Everything will still work, but the pump in particular has an in-line resistor to drop voltage from the expected 11.1 to 6V. The pump will still spin, but you may find that it's sluggish. If you're dead-set on the 2S battery, you can remove the resistor, or you can just get an 11.1V battery.

Ok Bob! Thanks for the heads up on the pump situation and battery size. I have a 11.1 volt 3 cell 30c 4000 mAh that will fit!

I do have another question?



In the above photo, it shows the ballast system items that are not being used now that my boat will go direct as a snorkel system.

Can I just eliminate that system? That piece on top is leaking from the valve itself as well and the part with the two screws!

Piccy no show, but with SNORT, you only need a hose going up to the surface and that's it. The snorkel valve and the safety valve are all superfluous.

SNORT is absolutely my preferred setup for virtually all boats. Stationary diving is for ballistic missile subs and research subs.

David and Bob, Thank you for answering my question! I sure do like the simplicity of the snort system!

Making some progress on the "Hunley"



Getting ready to install the hatches, and the snorkel tube housing. I will put up some better photos and descriptions of my progress soon!!

I know this "HL Hunley' build has not been one of those so called dynamic builds, but I am here to say it is complete except for the final finish work!







Before anyone says anything about how I have fabricated this boat, please note it may not be true to scale in all aspects of the "EXACT" HL Hunley! If you go out and research this boat you will find a ton of different looks for this boat! I took it upon myself to build this boat so it would hold up during water operation and yet stay close to the original full scale form. You can see by the acrylic paints that I have on the desk it suggests it may not just be all flat black! I may give it a more rusty looking finish!? Not sure yet!

I will post up the final photos of the Hunley and the Housatonic together when finish is complete! Thank you for looking, and thank you for all the help and advice I got on this build!!

Great work, Rob! Not sure if you've already been hit by the rivet-counters, but if so, tell them to pound sand. This is your boat. If you like it, that's the only thing that matters. I think it looks great.

Thanks Bob! I am finding out one thing for sure! Skill, knowledge, and patience is required for this hobby! I am gaining a lot of skill and knowledge, but I lack the patience it takes to do it right. I tend to get in a hurry to get the submarine I am working on done so that I can start the next one. I have built 10 in the water (Surface runners only, and stand off scale) submarines since I got into this hobby a year and half ago!! None of them are even close to the beautiful workmanship that I see from the group of guys on this forum!

"Perfection is our goal. Excellence will be tolerated" I see both perfection and excellence on this forum, and most of all I see the patience required to achieve both!
