    In this post I will show you the conversion from SimLab GT2 rig to 2DOF.
    First I have examine the options on how should I have done it since the problem is that the GT2 rig is compact and I did not want to make it biffier. I have got a lot of usefull info from this build https://www.xsimulator.net/community/threads/my-project-2dof.13425/
    This was the original look of it.

    First I have tried to design the mechanical things to be able to mount motors and design the arms/shafts for them. Since the pictures says more than thousand words this is the result of the temp solution I have come with. It is still not 100% fixed but till now it looks like it will be the best one to mount the motors to the rig.
    The arms are made out of alu and are adjustable. A was able to design the rig so that the whole platform will be just around 5cm higher.

    To mount the pots to the motors I have designed the mounts for hall pots. You can find the files on https://www.thingiverse.com/thing:3921212 Some were downloaded from other designs like for the e-brake.

    To mount the seat I have used a pivot mounting bracket that you can also see in the pictures with ruler so you can get the impression how big is it.

    I will be also able to fit the bassshakers to the rig. They will be mounted under the seat and will be able so transfer the shakes more efficient since they will be in direct contact with seat mount and will not transfer the bass through pivot mount. They will be also cooled since they can get hot.

    Since those motors are not self locking I am going to use some kind of belt tensioning to keep the seat in center.
    For now I am happy with the look and feel of he mount design of motors to the rig and my next post will be how I have designed the control box unit.

    Here you can also find the list of tools, materials and parts (pots, motors,....) I have used:

    The second stage was to design the 2DOF control box.
    I have used old box that was thrown away and modified it to fit all the components.

    Below you can see the pictures but basically it has a 24v 600W power supply, 12v fan controller box with alarm if the fans stops spinning, 2x silent fans, 2x IBT2 pwm controllers, ardino, kill switch connected to 220v with front mount diode to signal if kill switch is active, 5010 diode to protect from power supply tripping and illuminated on/off switch.

    Front plate, arms, fan brackes and some other parts were 3d printed.
    Before the final assemble it was painted.

    Now the next step is to test motors outside the rig, final mount the gt2 rig, create balanced tensioners and also apply for the SimTools license.

    If someone needs some additional pictures or. parts info, I can post them.

    Awesome!

    I've been researching doing this to my GT2. Will be following closely, thanks for sharing!

    Quick question, what's the part detail for the seat mount and motor arms?

    They are custom made. My friend did them for me. Source files for arms are available on thingeverse.
    For pivot mounts you can see on the pictures with the ruler how big they are. I can measure them for exact numbers. I have draw them quickly on the paper and he made them.

    Today I have got the license for the simtool. TNX about that. Now I have to earn enough coins to be able to download plugins :( Is there an option to get for testing just f1 2018 plugin and dirt rally 2?
    Maybe it is a stupid question but is donating of coins possible :/
