Shapeoko 3 - Walnut Carbide Logo

[edwardrford]

Hi All - I spent some time today playing with the new aluminum table and clamps. Here's a video of the Carbide 3D logo I cut from a piece of walnut I had in my bin.



Job Specifications:
Stock Material - Walnut (11-1/2" x 5-1/2" x 7/8")
Cutting Bit - 3 Flute, 1/4" Square Endmill
Total Cutting Depth - 1/4" (0.25")
Depth Per Pass - 1/8" (0.125")
Feed Rate - 60 inches Per Minute
Plunge Rate - 30 inches Per Minute

Total Job Time - 13 minutes

After it was all done I trimmed it to size (removed ends) with my bandsaw, then wiped it down with mineral spirits. Tomorrow I'll apply a coat of tongue oil and call it good.

Very slick. Chewing through that walnut like walnut butter.

After using sticky tape for a month making really small parts, I'm starting to mill out larger stock again and I realized that I never fully appreciated the need for strong, bulletproof hold downs. Out of curiosity, is there any reason why the new table couldn't be retrofitted to an appropriately sized S2?

@brian - i actually have a table like this for my shapeoko 2! Someone here on the forum made one for themselves (a few years ago) and I asked (and paid) for them to make one for me as well! Same principal, but it was 1/4" aluminum if I remember correctly, so it wasn't as large or as heavy, but it still added a lot to the machine in terms of work holding.

A better alternative for an aluminum table for shapeoko 2 is the misumi table extrusions - i'll try to dig up the part number.

Misumi table extrusions are from the HFSQN4 range. Mine were HFSQN4-15250 and are fantastic on the SO2!

Thanks guys. I'll definitely look into that.

It would be interesting to see what is the optimal arrangement for an SO3.

I'd also dearly love to see a CAD file or the specifics of the hole spacing / pattern which was used.

(guess I'm going to have to order a whole bunch more T-nuts)

@EdwardFord - I recently found a tip for a better finish on the flat bits of wood - Try to make 'raster' cuts in the direction of the grain in large flat areas and the ridges will disappear.
Great fun logo though!
