New Toy For The Swimming Pool

[rwtdiver]

Before I get to far along with the main body and electrical WTC I want to set up all the electronics on a static board and test it out before the installation into the boxes.





I do have a drawing showing the preliminary design for the thruster's operation. My plan now will be to install the layout on a board and do a complete run check before installing this set up in the watertight plastic boxes.

Rob,
That translated to metric means about 1,2 mtr in lenght, not too big and easy to handle for getting her in the water, do you give the PLA a coat to get it more UV resistant?

Manfred.

Hi Manfred,

Sorry, have not got used to metric yet.:-)) Working on it!

The weight issue is still out. I printed my shark at 100% infill which I am sure will increase the weight. The original designer suggested 25% and using PETG filament. Yes I will be applying some color to the inside to help seal it there as well as some color and clear coat on the outside. I won't need to overdo because at 100% UV won't be an issue for me because it won't be outside and in the pool for very long at all. I have never had any problem with any of my submarines that are printed at 100% infill and sealed.

Manfred,

Sorry for my delay in answering your questions.

I do not remember the exact time it took to print out, but a 100% infill I am going to estimate at about 60 t0 80 hours. I use PLA on everything I do because of the environment that I have to work in. The total length of the shark will be at 48" give or take. As to weight, not sure at this point.

Back at doing some more sanding and fitting. The electronics mounting unit needed some clean up so the the two plastic watertight electrical boxes would fit properly and be just snug enough for a good fit, yet not to tight so they could be removed for repair work if required.





With this unit completed I can begin to put the main hull section together.

OK!

As to why I shut down this build and why I am reposting? A senior moment (at my age that would work) I think we will just go with that.
The next few pages will be all the photos of the shark build up to this point.













The three photos above show the mounting system for the two watertight boxes used for the electronics.



The three photos above show the two thrusters and how they are going to be installed.



The above photos show how the hinge connection will be made for the tail sections.



This last photo is where I left off. I took all the tail sections outside to sand and clean up the tail sections.

At this point I will pick up the build and start to show the actual putting it together along with the electronics and final testing and finish work.

Again, I apologize for this interruption in the build.

Glad you brought it back here!

Rob.

You gotta love 3D, giving you the possibility to make exotic models, me on the other hand i'm a classic builder, works for me, a question for you, total time of printing?, material used?, what will be the lenght of this shark? and the total weight when completed.

Mine is a little more advanced. Printed with Bambu X1C too


I'm still waiting for the waterproof 3p connectors for the motors.
The only point to improve in my opinion is the pectoral fins that I find too inclined downwards and the teeth that I will redo myself with pieces of ABS

Ducting looks too far back ( yellow dashed line) , the last 1/4 missed the gill slit.
May or may not have deleterious effect on performance.
We'll see during testing.

I just noticed spellcheck changed all my Bambu to Bambi HAHAHAHA

[trout]

Bambi has done some amazing work on their printers. I think you will be very pleased with the results. My son worked for a robotics company and ran the Bambi through its paces. The results were incredible.

Thank you David, and Tom!

Manfred, and Rick, As I stated above this build has been discontinued. Thank you for the suggestions

Rob,
would love to see a build of the USS SEAWOLF 575 boat. Do you know of any files of that one?

Why don't you make hinges on the gills,so they can open enough when going forward
Or control them by a servo to open them on command

Manfred

[Rick Teskey]

Knock out the gills all together that might give the thrust needed
