As I see fingerprints and ripples in your paint iwo your scribing.......I think it isn't hardened out yet.....believe it needs more time before you start scribing the butter feeling will disappear.

The primer has cured overnight and into the next afternoon, and seems to be perfect for scribing. So off I go again...re-marking the upper hull.

Well, I feel much better now. It's not perfect, but it will do from a distance. The first round of scribing on the upper hull is finished. All that is left is the sail, but that will come later on. Next step is to dig out the limber holes. Yay.

Re: Matt Thor 60" 1/72 Scale Akula II

I went on a little tangent this evening. Seeing the scribing near the bow reminded me that I wanted a buoy on this boat. On the real sub it stands out a good bit in its bright red and white, contrasted against the black hull.

I decided to print this piece out on my 3D printer. Since I have a printer that can do different colors, the red and white shouldn't be a problem.

First step was to design the buoy in my CAD software of choice. It's easy and straightforward...and free! The buoy needed to be 24mm in diameter to be of correct scale.



The printing process itself only took about 20 minutes at standard resolution. I may do it again in a finer, better resolution later. This was a proof of concept test.





You can see the scribed circle where this will go. I'll have to file out the hole and recess the buoy into it so it's almost flush with the hull.





That's all for tonight methinks.

3D printer. hah!
That's just not right!
I don't have one.
In fact I won't even go look at one.
I am afraid one will follow me home.

Nice work.

Question.
3D printers.
The higher the drawing resolution, the more detail on the printed part?
How much detail can be made?

Correct....higher resolution = better detail.

As for how much, each machine is different. In my case, my printer has a resolution of 1/10th of 1mm, or 0.10mm. The buoy, however, was printed at the "standard" 0.2mm per layer.

It really has come in handy. for example:

Are there any 3D drawing programs that are not vector-based? In other words, drawing resolution shouldn't come into play, yes?

Jeff,

As far as I know, the answer is No. You are limited by the physical characteristics of the printer. The nozzle shoots out a stream of melted plastic, and that can't be infinitely small.

Re: Matt Thor 60" 1/72 Scale Akula II

I should clarify, Jeff...the resolution of the printed part is NOT dependent on the resolution of the drawing. The part's resolution is determined by user input, i.e. you choose how thick to make the layers and therefor how smooth the printed object will be.

Erich,

That's how I have understood the process to work. Tnx!

Jeff,

I'm bringing some fun stuff I've printed to the April meeting so you can look and touch.

Re: Matt Thor 60" 1/72 Scale Akula II

Ok, time for today's round of Akula.

I need to open up the vents on the top hull, all 32 of them. I cannot stress enough how much I HATE doing this. Seriously. I would rather chug fire hot sauce than do vent holes and flood vents. Sooo....I'm limiting myself to doing 4 per day. At least that way I can keep what's left of my sanity.

The rectangular holes were first bored out with a Dremel, then filed to shape with some small files.

Re: Matt Thor 60" 1/72 Scale Akula II

On to the next.....

I need an indexing lip near the stern of the upper hull in order to mate the final few inches of the stern of the hull with the rest, as it will be cut much like a Z-cut is done. The boat will not be a Z cut, however. The hull will split among the centerline, except for this section that will be cut off and mated to the lower hull.

I first checked the plans to give me an idea of how much room I would have to play with. The cut will be just an inch or two forward of the upper rudder's location. I then transferred the line onto the inner hull. Using the same process as I used for the indexing strips, I laid down duct tape, coated it with Vasoline, and laid down three strips of cloth tape. It will be set aside to cure overnight.









more later.....
