Help with molding

Machines (Original/PRO)

Hello all.

I have a friend who is trying to restore an old wooden window.

The bottom sash is totally dry rot and will need a new piece.

One of the center window sash is also in bad shape.

I am trying to use my onefinity CNC to create a molding.

I have Vectric vcarve pro.

I am fairly new to the whole CNC world.

However I am a lifelong woodworker, and have completed several CNC projects.

I have watched several videos on the vectric molding toolpath and am willing to give it a try.

I know I need to create a dxf file of the molding but unsure how to do this.

This is an end view of one of the cross pieces, the bottom sash will have the same design (one half)

I don’t need to design the bottom “tongue” as I can cut the rabbits with a router or table saw.

The dimensions are as follows”

Total width is .75

Total heighth is 1.34 (including the “tongue”

Top Step is .313.wide by .156 high

Second step is .563 wide and .313 high

Last step is .75 wide and will go the rest of the way to the bottom

I thought I might be able to draw an outline of the end view but not sure how to proceed.

Any help is greatly appreciated.

Mike

Perhaps use a different program to generate your DXF file. Although I’d think something like vectric could generate an appropriate vector pretty easily?

Something like this fits your specifications, although all edges are square.

No, you don’t need a .dxf file. Just import this picture into V Carve, and trace the vectors over the picture. Then use these vectors for the moulding toolpath.

You can copy outline vetric aspire 2 rail will mimic the outline to a 3D carve

I done have Aspire only Vcarve pro.
I have done some looking at the molding toolpath and think that is the way I’ll go.
Thanks

How did this project turn out? I have the exact same project/profile. I am very interested in if/how you accomplished this. I need to do 18 windows complete with the inverse profile on the endgrain. Thanks.

As you can see it turned out very well.

My biggest problem was the orientation of my material.
I kept trying to setup my carve on the face of the material.
once I changed it to the edge it fit just fine.

I would assume that would work for the end grain as well.

Dang! That’s very clean! Did you do the dado with the cnc as well?

Thank you. I’m new to this. I’m actually going to look at a machine for sale tomorrow. Your results pretty much cemented that I’ll get it.

I did the dado on my table saw.
It was very frustrating at first because I couldn’t get the orientation correct.

As I was checking the fit at one point, I happened to flip the material around and realized that I could get a good match on the edge.

Light bulb moment for sure :crazy_face:
