    Just wanted to share my build for any anyone who is thinking of building their own seat mover. This was such an awesome project! I have not completed anything of this magnitude before, but I learn a lot along the way! This forum is a deep well of information but sorting through can be a bit difficult, especially with some builds and information that is a bit outdated. Many thanks to the active members on this forum that provide constant support!

    For this first phase, I tried to keep welding to a minimum and used 2x4s for most of the construction. The plan is to keep things flexible for future experimentation, expansion, and keep initial R&D costs down )

    General rig build info:
    PGSaw 25:1 180w motors
    HP ProLiant DL380 575W power-supplies
    BOURNS 6639S potentiometers
    JRK 18v19 motor controllers

    Transducer setup:
    2 x Auras 50W
    MEAN WELL LRS-200-24 powersupply
    Sure Electronics AA-AB32971 2x100W Amplifier
    2 x USB sound cards

    Product of all the sufferings)

    We all got to start somewhere )

    I really like my driving potion, so I tried my best to recreate all of the measurements, pedal, seat, steering wheel height.

    I went with a 2 x of Flange Yoke as suggested by someone on this forum. Putting U joint together was not as easy I thought it would be, using proper tools would have made this part of the project much easier. I don't own a welder but have access to one, so for the initial version of this project I decided to bolt things together and get it working first. The threaded rod helped a lot with front to back flex in the brackets.

    I used a project box to house the JRKs mounted on Nylon spacers, and ran dual 60mm fans to move the air over the JRKs. I also soldered the wires directly to the boards as terminal blocks are only rated for 16 A.

    I soldered all the necessary pins together rather then running multiple connectors

    This bracket was perfect thickness and spacing was a hair over ~55mm, exactly what I was looking for

    I was able to pinch the gearboxes on this 2x4 on both sides, this setup seems to hold up to the abuse so far. I went with QA1 Precision Products NFR8 rod ends, and used wheel nuts instead of conical spacers.

    I decided to go down the wrap route.

    Was lucky to find this suede like material for the "dash") Came out really nice.

    Built a little enclosure for all of the electronics in the back

    I spent a few hours on the simulator before tucking all the wires away, and decided to expend this first part of the build and go for the bass shakers setup. I felt like I was close to what I wanted out of the setup, but something was missing, and for me it ended up being the missing bit.

    I mounted one in the lower back area, and the second one right underneath the pedals

    All of the business in the back ) I already have the 3rd JRK motor, TL is somewhere in the future, but at the moment this will do!

    Hi, Great build by the way. I am looking at adding more transducers to my RIG. I have a single buttkicker gamer mounted to the back of my motion platform now, but wanted an opinion on the 2 x Auras 50W
    and your Sure Electronics AA-AB32971 2x100W Amplifier. My question is - if you mounted those Auras in the front of your rig (that's what I am planning to do btw) would they have enough power to simulate curbs etc..
    If you have a chance, take a look at my rig.. here https://www.xsimulator.net/community/threads/full-frame-2-dof-traction-loss-new-build.14740/
    Thanks! D
