    Hello all,

    I'm currently following Floriske's 2DOF sim build. Here is the link on x-sim:

    http://x-sim.de/forum/viewtopic.php?f=36&t=617

    Its profile is just what I'm looking for, he's made his plans available, and detailed his process very well. That being said, I'm struggling with acquiring / creating a working U-joint. The solutions I've found online all seem to require some welding skill (of which I have none, let alone a kit), and haven't been able to find a solution.

    Can you think of anything off the top of your head that may substitute well or am I SOL? Thank you for taking the time to respond - I appreciate your feedback!

    @Zyadox
    I am only new here, but I think @Wanegain did a design using spherical rod ends for a uni joint. No welding needed. I have also seen a car engine mount used as it has bolts going through it and I think a draglink setup was used to stop torsional twist.
    Im going the cut down uni joint as I have a welder.
    .....I really must note down where I find this info and link it.....:D

    I use a universal joint from an old car tailshaft, it requires cutting and welding on a mount plate but is strong and very smooth in movement.

    Other use a steering column universal joint, some fabricate a joint from multiple rose joints.

    Thanks for the feedback, everyone!

    @Wanegain , fantastic idea! How would you describe the durability, angles of movement, and stability of your idea? It seems to be just the solution I'm looking for. If I may, what are the rod ends attached to in the middle and what size are your rod ends?

    The durability depends on what material you use to fix it, but the universal joint itself should not be degraded.. For angles there is no restriction. With this solution, it's possible that there is a small backlash because of the elasticity of wood. I am using 10mm threaded rods.

    I highly suggest using the Fully captured Rod ends if your going to use that route...The cheaper rod ends IMO slop out alot faster.

    I had a hard time finding a U-Joint, so I purchased:

    One:
    Spicer 5-1310X U-Joint Kit 1310/SPL22 Series (OSR)


    Two:
    DRIVESHAFT FLANGE YOKE - 1310 SERIES - PDM 2.75 FFC 1.375


    @Admin, if you can provide instructions on how to provide links to the products listed and how to upload a video I'll demonstrate the final product. Keep getting flagged as SPAM.

    I got mine on ebay, has bolt holes on both ends so you may be able to find a weldless way to attach. Search for "CARDAN SHAFT FLANGED UNIVERSAL JOINT U JOINT HIGH ANGLE"., cost is about 65$ usd.
