A little help please

Post by Jan.vanderlinden »

I only have desktop.
Would someone be willing to make me a 3D model of the attached cross section view?
This represents a 12" section out of the center of a whiskey barrel stave.
The stave needs to be 5" wide.
I appreciate your help.

You could probably do this using moulding toolpaths. But here's an STL and Rhino 3DM file compressed into one ZIP file. Try the STL first.

I think that you meant this file for someone else.

Hi Steven,
Thank you very much for the model.
However I must be doing something wrong.
I'm trying to make a whiskey flite, but when I create the 3 places for the glasses, project it onto the 3d model and run the simulation, the board comes out flat.
What am I doing wrong?

EDIT.
I suppose it would help if I ran a surfacing toolpath. (how embarrassing)

Hi Steven,
Well I should have known better.
Whiskey barrels also are round.
Would you mind adjusting the model to include the end view?

Technically their staves aren't straight-sided either. But, here you go. Again a Rhino 3D and STL file. Note: your end view PDF was 4.25 inches wide rather than 5. You could scale just the Y axis to 5 on import, if that's what you really wanted, and it shouldn't affect the curve all that much.

For the modelling curious: I placed the vectors in each of the PDF files at right angles to each other (verticals hidden in the image below). I then used a one-rail sweep (sweep1) command to run the short profiles (in blue) along each of the long rails (in red) to get the two compound surfaces. You could sweep long over short too. I then used the edge surface command to fill in the four walls.

Steven,
You're a prince.
What I'm doing is working with 12" sections cut from the center of staves.
Their going to whiskey flights for tasting get togethers.
I realize that I gave you the wrong dimension, (it is actually 5" wide) but I don't think it will matter much as I only needed the compound surface to project cuts onto.
Thank you again for your help.
I'm going to try it out today.

Steven,
Well 12" is not long enough.
The glasses are to close together.
Would you please make the model 15" long X 5" wide.

12" not long enough? I just went to my cabinet and measured up a few of my glasses. Glencairns, Reidel, Urban Bar copitas, Rystal copitas and even a Blenders glass, all seem to run from 2 3/8" to 3". Even my Manhattan tumblers struggle to break 3 1/8". What glasses are you going to be using?

12 inches minus 3 glasses (from image above) times 3 inches = 3 inches. Divide that by four (2 spaces between glasses and 2 spaces between glasses and object ends) = 3/4 inch. That's reasonably tight.

Model curves scaled to 15 long and 5 wide. Surfaces re-swept from that.

Thank you Steven.
That will work out great.
I think our titles should be reversed. :D
