Making a trivet from scraps

[WillAdams (William Adams (Carbide 3D))]

as requested on support…

…glue up 9 pieces of 3/4 inch wide by 10 inches long strips of maple and walnut and leave about 2 inches on each end and cut out the inside, every other one.

Basically, what one does is draw up the glued-up stock, and then set up the cut to match:

and make layers for each:

and put things on them:

and duplicate as needed using Linear Array:

Things are clearer w/o the Grid:

Then draw in rectangles on the DEFAULT layer:

and duplicate them:

(grouping the output)

Probably the origin will be easiest if it’s at the lower-left corner, so select everything and drag:

To ensure that the interior material will be fully removed, offset a bit:

(adjust that value for how precise the glue-up and your securing and setting origin relative to the stock)

and then assign a toolpath:

If desired, add a roundover using a suitable tool:

Using unsupported tooling in Carbide Create: Roundover / Cove / Radius bits

These are usually used in routers for decorative effects in wood: https://www.whitesiderouterbits.com/products/1570 but they are potentially useful for joinery: They are also useful for rounding off parts to allow rotary motion as for a hinged lid. Unfortunately, Carbide Create does not support this endmill geometry — but using the new support for previewing a V endmill when used in a No Offset Contour toolpath, it should be possible to preview them w/ confidence by stacking a series o…
