Carve and Burnt Look onto a Pine Board

I am sure there must be a current post on this but I have not been able to find one.

What I am trying to do I think should be pretty easy. All I want to do is to carve an SVG of a fish onto a round pine board and then get it to have a burnt look.

Does anyone know the steps needed to accomplish this?

  1. How deep of a cut do you suggest?
  2. What type of endmill is suggested? I guess I could experiment on some scrap boards first to answer these questions.
  3. How about finishing the project? Do I just put on a few coats of poly? Or is there any other suggestions on this?

I would suggest using ball-nosed tooling and texture toolpaths for this.

Grab a fish from somewhere — the Elements Library has a couple:

scaling it down to a reasonable size:

we get a design which has a mix of closed (indicated by being black) and open (indicated by being magenta)

which wants an assortment of toolpaths.

First, the open geometry is only suited to being cut w/ a No-offset Contour toolpath:

Select a tool which matches the scale of the design you are working on:

and verify it with the 3D preview:

which seems a bit heavy, so we switch to something smaller:

and adjust the Depth to match the radius of the smaller tool to get:

which seems reasonable.

There are some small details which really can’t be cut save as a V carving — use a tool which is as acute as necessary to cut as deeply as one wishes:

(note that there is one outline which we will want to add to the above contour)

but perhaps a more acute tool would be better:

and maybe we should go smaller with the ball-nose so as to better match…

which just leaves the surround.

Draw in a rectangle:

and reduce it a bit:

and we then decide to ensure that the fish outline is cut consistently with the rest of the design so we select the outlined elements:

and add the fish outline itself:

and modify the outline cut to match:

which now previews as:

Next we cut around things:

with one size ball-nosed tool:

which previews as:

We then offset the fish by the radius of the ball-nosed tool:

and use that and a smaller ball-nosed tool to cut a texture which starts at the bottom of the previous pocket and cuts a bit deeper:

which all previews as:

and should afford a good mix of plain uncut areas which won’t burn much, and textured areas which will burn.

I’ve made a flag that I gave a burnt look to it. I just used a small butane torch to lightly burn it. Then I have used both shellac or polyurethane.

I guess I am looking more like an actual burned wood kind of like what Brew described. Like to torch it after carving. Is there any tips on doing that? I read today about some aluminum oxide added. Is this necessary or can I just carve using a ball nose and then touch it with a torch? Will that make do the trick? Maybe I am making to much out of this and it is really that easy.

I haven’t tried the aluminum oxide. I’ll have to look into that. I’ve always just made the cuts and used a small torch. The key is to not hold it too close for too long. It’s much better to go over it back and forth, kind of like not trying to burn the marshmallow of a s’more.

It’s pretty easy to torch pine. There are a million ways to do it. Here’s a good tutorial.
