The New Hotness

  • OMTech 60 W Laser: Improved MDF Spikes and Stops

    A bit of tinkering suggested I needed a way to repeatably position stock sheets on the honeycomb, so I conjured stops that would be slightly taller than the magnetic spikes:

    Three of those form a corner into which you can tuck victims of the same general size:

    Those pointy MDF spikes should start with slightly rounded tops, because that’s what they’ll look like after a few uses:

    I also made a low-profile stop for victims lying directly on the honeycomb for engraving:
