    Ok, I had the idea of a weekly challenge. It fell off the rails.

    This week: Hole drill jig body tubes. Due next Thursday. Post submissions in this thread. If you don’t have a printer, I can print it for you.

    If you like the idea for a challenge, like the thread. If you have a idea for next week, send me a PM.

    Chuck, a drill guide for tubes? to get holes drilled perpendicular to tubes, and in a specific spot?

    To fit any sized BT? Or are there limits?
    To drill any sized hole? Or are there limits?

    I am thinking more about to drill 2-3 holes for vents or for rivets.

    A perfect case for a parameterized openSCAD model. Though I guarantee I can make aluminum ones faster on a lathe than you can print them :)

    Here's a starting point. It's an OpenSCAD customizer program. The cut-out rectangles in the ring can take any of the four generated drill guides. The notches can be used to make evenly-spaced pencil marks. If you print two rings and lay them flat on a table, you can get vertically aligned marks. With two rings, a table saw, and a fence, you can cut fin slots!

    Enjoy!

    I would like to have drilling jigs to drill cores for grains.
    I make the jigs to hold the grains out of phenolic liner material.
    A plastic cap with a lip would be nice to fit over the liner and the center for my core drill.

    I can give you ODs of the liners and what cores I would need.
