Darrel Anderson of Bon Accord, AB, created this geeky trivet as the first project with his new Mark 3 CNC.
This is a trivet, in other words a thing to put a hot pot on. The design is a hilbert curve, actually 4 hilbert curves connected to make the one continuous line. The wood is cherry. I really like cherry because of how well it sands to a glossy finish.

This is technically four order-two Hilbert curves joined in a way that makes them one non-Hilbert curve. Reading the furnished article, I see that he makes the same distinction himself.
All of that needless pedantry aside, it’s a beautiful trivet – and really restores my desire to have ready access to CNC.
I really like cherry because the sawdust smells awesome! I have a CNC project coming up on a piece that’s a combination of cherry and walnut. When the 1/2″ endmill is doing the rough pass, it burns the wood a little bit when it stops to change directions. I could probably fix it by changing the speed, but it smells so darn good! Kudos to Darrel for an excellent trivet!
Yes, that is one thing to watch with cherry, passes that are too slow will burn up a bit very quickly!
