How To: particular design patterns

[davehunt00 (David Hunt)]

The image below is a type of pasta press. It is likely hand-carved - supposed to represent a head of wheat (upside down here).

I’m using the free version of Carbide Create.

I’m trying to figure out how to replicate the grain aspect of the design. I think with a 90 vee I wouldn’t get the oval/canoe effect seen here in the grains - it would end up having a flat bottom or angled ends. Is there a technique that would mimic the result here - basically a single bottom “keel” that is curved on the Z axis?

I think the bristles will be ok with just a vee (maybe a deeper 60 vee) on a straight segment.

Thoughts?
Thanks!
Dave

I am sure someone will help you with this.

However my question is what does this do. Do you squeeze pasta dough through it or make impressions in a rolled out dough?

If you have Carbide Create Pro then you could model this in 3D:

by modeling it twice after first modeling the stock thickness:

then subtracting:

Yah, it is a ravioli press. You lay a thin layer of dough over top, use your thumb to push in the bowl part, put in your filling, fold over more dough to seal it, flip the whole thing over and press down to get the pattern pushed into your dough. Then trim the edges to make a ravioli square. Repeat x times for dinner.

Thanks Will. That looks like a really useful process for some things I’m working on. I’ll consider the Pro purchase.

Thanks!

I think a boring V Carve would do the trick.

I just over-lapped two circles, to make the shape:

Apply a VCarve with no depth limit, Using tool #301 (90 deg V Bit).

You’re correct, that will do it. I’m not sure why I thought it would bottom out and basically create a smaller, flat, oval bottom, but I’ll try this. This seems to work even with a larger grain than I would need. I guess it just finds the depth it needs.

Thanks!

@davehunt00

I guess it just finds the depth it needs.

This is exactly how the V Carve works. It goes as deep as needed in order to touch the design around it.

You can limit the depth to get a flat bottom if you like (useful on large designs).
