    Plans for a Kant Twist Clamp

    Welding is efficient, but you need the right tools. Clamps are one of those tools, which come handy in metal- and also wood- working. This design is based on an expired US patent US 4,276,692.

    This video is about a model and plans to manufacture the featured design.

    The plans are published under TAPR open hardware license.

    This is really interesting. Finding expired patents and then open-sourcing them as plans, with voiceover videos showing the plans software. Cool! We do know that homemade tool guys like these three things (plans, tool making videos, old patents), so it's interesting to see them combined like this.

    Here's US patent #4276692, upon which these plans are based. Click for the full patent.

    I'm working on a pair of clamps from these plans now. I did opt to size them down a bit for my needs. Surprisingly it's taking a LONG time to complete! lol They better work good when I'm done.
