  • The Best Food-Safe Finish May Be None At All - Fine Woodworking Article

  • Maybe, but your examples aren’t repeatedly wetted and dried. Could the repeated cycles cause the particles to move deeper?

  • The illustrations seem to indicate that stains and dead microbes accumulate in the middle of the wood, deep below the surface. It would be interesting to slice an old wood cutting board in half and see the accumulated stains!

  • The science on plain wood being safe has been around for quite a while. I remember reading a study many years ago where some scientists mashed bacteria all over the surface of a wood cutting board, rinsed it, dried it, and then tried everything they could to get the bacteria to transfer to fresh meat (including trying to pound the meat into the board with a mallet) and the meat remained uncontaminated. So, it seems like the safest option is a single unglued plank of wood.

    Glue joints don’t act like wood, so presumably that makes bamboo act less like plain wood safety-wise.

    The problem with plastic is that the knife marks can retain bacteria (which, unlike wood, the plastic doesn’t kill).

  • Did you see the pictures in the article showing how stains disappear?

  • The article discusses glue joints. Did you make it through the whole article?

  • Tangential on the broad face would mean it’s flat sawn (plain sawn). Like how woodworkers care about tangential vs radial shrinkage of wood species.

  • Table saw blade recommendations?

    Jump

  • I ended up choosing a CMT 24T ITK (thin kerf) blade, which worked fantastically.

  • Why not a 24t for ripping?

  • I’ve seen his recommendation too but that’s another 2x price jump over the price range I’m already trying to avoid!

  • Does the blade have multiple notches to allow adjustment as you sharpen it? Are you using the notch that makes the blade shortest?

  • Building an adjustable router dado jig!

    Jump

  • Yes, thanks! I have clamped one piece to guide my router before, but using two would be much easier since it eliminates the need to measure the offset to the “far” stop every time. Clever!

  • Can you elaborate on this a bit?

  • Scaffolding jack screws for a vise?

    Jump

  • Thanks. Interesting point that even a small bolt is going to be plenty strong for work-holding. So maybe just some all thread of appropriate length? I guess the problem there is the pitch is fine, so it would move very slowly.

    Out of curiosity, when do you care about the jaw being flush with the workbench top?

  • MIT Demonstrates Fully 3D Printed, Active Electronic Components

    Jump

  • My quick and dirty math based on some captions of the figures from the paper suggest it’s unlikely they’re getting amplification for now, because it seems like the even the “low” resistance state is quite resistive. But I still suspect it can be done, and they do characterize their structures as “active” - thanks!

  • Well, a logic gate doesn’t fundamentally have to amplify… if the control current exceeds the output, it isn’t amplifying but fill performs logic. I am too lazy to look myself, but did they demonstrate amplification? If not, I think it’s doable.

  • Couldn’t you build an amplifier by using a thin wire that heats up a larger wire? If you size the large wire to minimize self heating, then a small current would cause the thin wire to act as a heater, switching the large current.
