Victor III

[SSBN659]

Bart, I've been watching your build of the Victor III from the beginning and have really been impressed with your work. When the thread stopped I wondered what had happened. Now I know and I'm even more impressed with your work. Great looking Victor III. Thanks for posting it.

Posted in the right thread now...LOL
Some time pased.....did a long time nothing. Reson think Bob's post says it all https://forum.rc-sub.com/forum/gener...g-announcement
Did not know how I would be able to make this work, to make affordable models, I can't.
Past year I have been making 2 turnkey scale models for a company one static, one RC.

It did trigger somthing, and after chatting with Tom Spettel recently, I started to detail the VIII. I added panellines and scribelines the the 3D model, thinking on printing the sub, but not yet sure test print will provide guidance.

Below pictures of the 3D model in its current state.

Hi gents,

Some time has past sinds my last post, I was bored with the production work, so I started preparing my next project.
I also hit a roadblock on the VICTOR III. It is not uncommon when creating things, but this was a major one for me, and wanted to share.

I made a choice in the density of the tooling board before starting this project, Density: 0.45 g/cm³.

First, I encountered some scribing stencils problems, then I however encountered some scribing problems with the material itself. It seemed that the density was to low, scribing results were returning horrible, the material didn’t ship all the time, sometimes it just was compressed, especially in the corners. Very frustrating.

So I laid the hulls aside but that didn’t solve the problem.
Alter some time off I decided to rebuild the hull from some harder material. I decided to print the bow as a test piece.
The scribing was a relieve the material was hard enough and returned a scribing perfect result.

I re-designed the hull and printed all the parts. After 120hr the parts were finished, and everything was glued together.
The picture below shows the old and the new, the old shows all the scribing attempts, the new hull is partly sanded, the bow is coated in primer (the test piece), the torpedo hatch was the test scribe.

Test fitting rudders and palnes before making the toolings, all parts are registrated by means of dowel pins. Perfect fit and easy instalation for the end users .

Thank you?....some foreplay would have been nice Tom...

LOL, I almost spit my coffee onto my keyboard. That made my day.

He is right David, it is your fault. Thank you.

Thank you?....some foreplay would have been nice Tom...he will now come up with another "innocent" question
(and don’t tell him that I have enjoyed designing them)

not my fault....It was your idea, you started it sir....see below.

A practical articulated control surface?...

You nut! You European's are a scary bunch.

Are you going to articulate (variable camber) the bow planes?

You mean we make the "flap plane" work. Are you trying to kill me mr Horrible?

Last of the outfittings.

Spent most of the yesterday on designing, tweaking of the fwd dive plane until I had a working prototype.

The plane is a “flap rudder” type or “multi-section” rudder. The hinged aft section gives the rudder an extra control surface therefore enhances its efficiency.
When the helm is applied the angle of attack of the main control surface changes (working of a normal rudder), in addition the angle of attack of the flap also changes.
If the main rudder rotates 45° the flap turns an additional 45°. The flap is making a 90° angle to horizontal.

Pictures showing both 0° and 40°
