    Yoke mechanism part 1

    Okay, as promised I have made a few drawings and taken lots of shots.

    Tools needed: Grinder, lathe, MIG-welder, TIG-welder, drill with support, plasma-cutter and some regular tools. I dont have all of these tools myself, so some of the work is done by friends and companies.

    Parts needed: 4 bearings made by KOYO. I dont have the part number but show the supplier the photos and tell him that it is for a 12mm shaft/bolt.

    2 pcs M-8 ball links for cylinder, 2 pcs M-12 ball links for linkage between yokes and "triangle". Several M-12 bolts and nuts.

    I have not made any drawings for my cylinder setup. Not needed. The pictures will tell the story. Only thing important is that the end piece of the cylinder bust be as long as the threads on the banjo-bolt. And when making the nylon parts in the lathe, make it tight. Just like a tire-pump

    Here we go:

    More shots:



















    One important thing to add: All ball links must be taken apart so you can grease them. Lubricating is important

    This complete setup will fit within 20cm under your simulator floor. The floor should be on top of the 14cm high bearing-mounts. These on top of the 4cm high square tubes is 18cm total height. But add approx 2 more centimeters for the lower "triangle" part with bolt and bearing installed

    I have calculated for a 16mm plywood floor.

    Great stuff Ivar. Thanks for posting the info.

    After reading the tool list I though you were building a starship instead of a yoke setup!

    One thing I forgot to mention here:

    The gas cylinders I use now is the 15kg ones. But if you want even more force on your yoke, there is enough space between the steel frame to use 25kg cylinders.

    Your choice

    Ivar.. I think you built that thing to withstand a crash at 300KIAS.

    Good Stuff. Nobody can tell you that you went light on materials LOL

    hehe, it is a little heavy to lift. Do noubt

    But it has advantages also. If I at some point want to install hydraulics/actuators for movement on this setup, it is sturdy enough for that also

    I dont think weight is an issue on this assembly.

    Crash??? what are you talking about

    Here they are. Had forgotten to post pictures of that. Very simple. Same gas-cylinder setup as on elevator, but smaller cylinders though. 8 kg gas-cylinders. Some kitchen drawer rails and picture shows the rest I guess
