    Hello,

    I'm intending to build a 2 DOF full frame motion sim. The only aspect of the build I have some uncertainties about is the u-joint. Where is the best place to get one, and what is a rough estimate on how much it will cost?

    Thanks!

    The cheapest option is to get get an old car tailshaft and cut the u-joint flange off and weld a mount plate to it.

    I used the u joint from the adjustable height steering column from a Peugeot 206 that was at the local scrap yard. its a lot smaller than a drive shaft u joint and wouldn't of had the same amount of forces put upon it and is usually a lot cleaner once removed and has 40mm of height adjustment built in IMG_0014.JPG . the downside is that its far more difficult to remove than a drive shaft and you will probably have to pay for the whole steering column but id guess that the breaker wouldn't sell many so u might get it quite cheep. I welded mine direct to the base and seat frame to keep the height to a minimum. my height from base to seat frame is about 120mm

    I have also thought about using an u joint from a steering column but is it stable enough and can it handle the load?
    There are different sizes but all are much smaller than a u joint from a driwe shaft.
