Carving smooth surfaces

When I carve hardwood bowls, parts of the surface are smooth and other parts are furry, due to the grain. Some woods, like hard maple, yield less furring. I could reduce the stepover or change the rpm or select a different bit. What would you recommend for obtaining uniformly smooth carved surfaces?

Finishing textured hardwood surfaces?

I've made bowls of ~1000 overlapping flattened spheres, 2 1/2 inches on the long diameters and 3/4 inch on the short diameter. So, surfaces are textured with about 1/4" variation in height. I'd like to learn an efficient way to smooth the crevices: where two spheres meet. The best I've found is New ...

Planing with a leveling bit

I plan to use the large (1.25") bit I bought for leveling spoilboards for planing the large top and bottom surfaces of square blocks, prior to carving. I would remove at most 1/8" of material, fixing bowing and sloping. I'd use the recommended spindle speed. I could compute toolpaths, or I could mov...

Running finishing toolpaths in reverse?

Calculated finishing paths start at the center of the basin and proceed to the rim. Is there an easy way to run them in reverse: starting at the rim and proceeding to the center? I asked Charlie, at Vectric, but I didn't get an answer, as far as I know. My toolpaths are in .mmg (Axiom) format. For f...

Re: Big wooden Threads

I want to make a threaded dowel extension as part of a new leg for an old table.
The dowel is approximately 4 1/2" long and 1 1/2" in diameter.

I'm assembling an Axiom Pro 8 machine, without a rotary accessory. For making these new legs, I may need a different machine.

Re: Duplicating a vintage table leg

I measured around 10 diameters of the leg and used a spline to make a facsimile of the leg profile. Apart from the octagonal segment, it's a surface of revolution. If there's an easier way to get a mock-up of a piece, I'd like to know about it.

Duplicating a vintage table leg

Is there an easy way to obtain the shape of the leg, made on a lathe? I traced its outline.
The tracing will yield formulas, which I can use to generate the surface.

I expect I'll cut the top half of the leg, turn it over and cut the bottom, but I'm new to
CNC routing.

Re: Engraving a bowl

Dear Mike, I'm planning to cut the bowl first and to engrave on it with the methods you suggested. When I do, I'll post photos here. I enrolled for the Vectric workshop in Las Vegas, 20-21 October. That will help me come up to speed, and, by then, I'll have some experience with CNC routing. Many tha...

Re: Engraving a bowl

Dear Mike,

Looking at your attachments, curves in mine can sit on the surface of
the basin of a bowl, which they circle.

Best from

Re: Engraving a bowl

Dear Mike,

Many thanks.

Can a "vector" be used to engrave one curve with one depth and another with a different depth?
I'm thinking I'd like a "v" profile. I might want its depth to change, along the curve.

Engraving a bowl

engraving_example.pdf I'm new to CNC and could use guidance. I'll use VCarve Pro. I aim to make a hardwood bowl and engrave its interior with a mathematically-defined set of curves like ones depicted in the attachment. The depicted curves would be parlayed into v-shaped channels about 1/16" deep. S...
