    Open Source Bee Hives

    I haven't really read the details yet, but from what I can make out the hives were designed in Rhino and are snap together plywood kits. Potential beekeepers get the plans and give them to their...

    "..............but do I need to weld all the vertices together where the objects meet?"

    In my experience no. Not for a cnc router anyway. You would for 3D printing. For a ShopBot as long as there...

    Brad, that was an interesting thread. I wonder if instead of the adjustable bolt a block of soft aluminium could be fasted adjacent to the spoilboard. When the table is resurfaced it resurfaces the...
