C130 tutorial

Have any of you tried the C130 aircraft tutorial on the Rhino3d website? I'm thinking about buying it to see how the propellers were done.

For what it's worth, I have the 'Form vs. Shape 1' tutorial and it's very high quality and easy to follow. It assumes a basic knowledge of Rhino. I imagine that the 'Form vs. Shape 2' (C-130) tutorial is equally as good if not better.

Depends what modeling you have in mind. If it is just to model propellers and render them then tutorial is good. If you need to model real propellers to be CNC-carved then it is bit more complex. I do model real props since Rhino 2 came out.

I've been trying to model and cnc props for some time now. I think profiles from Bates Engineering imported to Rhino and lofted, then cut with either a 3 axis router or maybe turned on 5 axis would do it. Still not sure. Producing the master this way might work, but how are they mass produced?

Trent2530,
I have a PropPro. Few years ago I wrote a program which takes airfoil coordinates and place them in Rhino's 3D space at the proper place ready to loft. The only problem with PropPro is that is generating very thin tips. Theoritically it is good - it reduces induced drag. In practice however it is bit dangerous unless you will use it as the core for CF or Fiberglass. Regarding your question about mass producing them - It is simple. If it is made out of wood - you have to carve it no matter what. There are multi spindle CNC machines and manual multi spindle copiers. To carve propellers you do not need 5-axis. 3-axis is more than enough. Here http://www.hsweb.net/propellers/P1001453.jpg

Sounds like I'm on the right track for the software - coordinates, Rhino, Visual mill and then cut it. I agree a 3 axis machine will do it, but I thought a 3 axis machine would be OK for a master for a duplicator and too slow for production. Multi-spindle machines? I saw one at a convention cutting gun stocks, who uses one for props? Thanks for the help.

I just talked to Sensenich. They use a standard 3 axis mill for aluminum and wood. Cut one side, flip it over and cut the other side.

That how I do mine!

I've been using SolidWorks for over 7 years now. I consider myself an expert user. I just downloaded the trial version of Rhino, played around with it for a second but quickly lost interest. I am reconsidering my decision...I want to get back into learning this program after seeing a few of the things modelled using Rhino on the Rhino Site. For those of you who know the two programs, how easy is it to learn Rhino when you are familiar with SolidWorks?

Thanks..........

I have just played with SW but my opinion is that Rhino is much easier than SW.

Never used Solidworks, but have played with Inventor and am currently learning Alibre (Xpress ). Same principle.

Rhino, on the other hand requires a very different way of thinking. There are plenty of tutorials on the web, and you can download the demo and play with it. But, you'll generally have to go about things in a completely different way than you would in Solidworks.
