Submarine707 Project

[Guest]

Nice CAD work. The pitch on the prop of that junior looks far too severe if you're intending on making it work.

Thats good to know thanks. For now it's modeled to look like the movie version and I'm not sure if I want to do it as a push or pull thrust. In the movie the prop is not intended as a means for thrust but rather electricity generation as the rear thruster propels it. All things considered, this is of course scifi we're talking about, but yeah its good to keep in mind these things as I bring it to market for RC conversion.

Cheers! more to come

Figured I'd post over here for any not able to see it on SP. I've been at work getting the UX to 3d printing, which I now have access to a carbon fiber and Nylon 3d printer. Here's some pics.

This will be powered by a pump not a direct prop. So it's water jetted. My dream of a jet sub is coming true. I will be printing out the various sections over the next few months. After this is the rear section that connects the pump to the rest of the sub. IT will house the pump system.

Chad,

The 3Dprinted parts came out really nice. What printer are you using?

Very nice printer! I did not know that it was possible to do carbon fiber printing.

Well I don't fee like I have done a very good job of keeping this post as up to date as my one on SubPirates, but in an effort to do so here I am. Posting. With that said here is my latest news on the subject of the various 707 projects. I have been working hard on many of my various hobby related endeavors, and the UX from 707R is one of them. In fact my whole effort began with this submarine as a passion to see a working RC version of it. However in all honesty it was the Goff Nautilus that started my passion for subs, but I guess you could say it was the 707 that reignited my passion for building a submarine after giving up on building an RC sub many years ago. I succeeded in seeing the 707II built as an RC sub but on it's first official run, I fried the motor because the prop was too heavy for it. So what you are looking at here is the final set up for the prints. I have them divided in to two pieces that "should" fit within the print bed for a single print run. I decided to include various parts on the print for both strength and simplicity. What you see as far as detail is actual surface detail no need for scribing it's all done on the print job. No need to carve out port holes, etc. Just a quick sanding maybe a little dab of bondo and viola one finished deck ready to go. Next it will be on to finishing the hull sections of which the rear is complete.

if beauty is in the eye of the beholder this beholder LOVES this beauty. Something about the whole thing to me is just IT...As a kid I always loved the idea of a jet sub with ports and an exaust like a jet then along comes 707R and I'm like wow! HOOKED!

The next post will include pics of the preprint set up then the finished product. I will also go ahead and show a comparison of the finished printed deck next to the hull I mocked up years ago in foam and plaster that I was going to use as a plug until I discovered the power of 3d printing and gained access to a carbon fiber printer. The cost of doing this myself is INSANE. I'm talking pennies on the dollar compared even just to doing through an online printer shop like Shapeways. When I did the 707 print it cost me about 350 for the whole thing which was super cheap for what it had, but at this size of the UX I would and for JUST nylon in white I would pay at least twice that. With this when all is said and done it will probably have cost me about the same as the 707 and for a carbon fiber print in Black with a way better surface than the previous prints from Shapeways. NO COMPARISON.

Looking good.

Ok I fixed it to reflect that I am PST. One slight update. So while designing something as complex as this is in CAD, I choose to use a lot of layers to specify whats what. Each part gets a curves layer each created surface gets a surface layer. The downside to this is that I forget I have layers to turn on when finalizing the build for print. Lucky for me I stumbled across some layers and turned them on. Here is the updated render with those layers on and added to the print.



As I said lots of layers:

Excellent CAD work!

It sure has proven to produce the best results in every way, but you know what they say....cuz I don't..does anyone know what "they" say..?

[cdivine]

I'm curious...would there be any interest in my posting videos of CAD how to's. In case anyone is interested you can download Fusion360 by Autodesk for free as an hobbyist user here. FYI I use Rhino (Mac), but it's not free. I use Fusion for some things at work because it has T-Splines included for free too, which makes it pretty versatile. I would likely teach principles of how to make submarine related CAD shapes. vs how to use this software that software. It's surprisingly easy. Again I personally prefer Rhino. If you're on a PC it's way better than the Mac version, but everything I've done has been on mac so you decide.

yes, oh yes, SO YES!
CAD and Rhino....Sub related makes sense!
Thanks Chad!
