    Im new to all of this, i just bought a g920 wheel and been enjoying it since 1 montht ago. Checking youtube I saw that there are simulators for racing games and I fell into the rabbit hole about these, I have seen a little and I want to make my own.

    now i want to design one and make it.

    You have come to the right place, the community here is very active, creative and knowledgeable.

    You will find plenty of helpful information in the FAQs to get you started: http://www.xsimulator.net/community/faq/

    In particular check out the Design section of the FAQs: https://www.xsimulator.net/community/faq/design-considerations-resources.24/category

    You can also search for specific types of projects/information using the Google Custom Search function on the Recent page: https://www.xsimulator.net/community/find-new/posts?recent=1

    If something sounds odd then look it up in the glossary: http://www.xsimulator.net/community/faq/glossary-of-acronyms-and-names.66/

    Document your project and ask any questions on this thread, that gives context and makes it much easier for others to make suggestions or give advice.

    The design you have depicted is a 2DOF full frame foot mount design, so search for similar existing projects you can study.

    Good luck with your project.

    thanks, im looking in the design considerations section and wow... Now I have a little more to base myself on what I'm going to do.

    Design
    After seeing many designs in the forum I think I already have a much better idea of what I want to do, I improved the design a bit so that it can be even more compact and can serve as a chair when I'm not playing. Imagen1.png

    The yellow part can be removed in case I want to use the chair normally, and apart from that it can be changed to be able to use it in different racing positions.

    The base is 40 x50 cm, I hope it is stable...

    Motors
    Regarding the motors, I really don't know how much strength they must have.

    Taking into account that 50rpm motors with 6Nm torque are used, these are the results that simcalc gave me

    Imagen3.png
    I don't know if the strength is enough to move or if I need a little more... and also if the movement is enough.

    With a compact design torque (N) is more important than outright speed, as it takes a lot to drive a compact rig with limited inherent design leverage. On the upside, movement of the base is amplified by the seat height.

    In terms of what you have in mind please be aware that a lever and rod are most efficient at 90 degrees, and effective torque utilisation drops off very rapidly after about 38-40 degrees in either direction from that. Hence the normal rest angle for this type of design would normally be zero and the max angle would be 40 or less.

    Also stick with realistic lever CTC length, I suspect with this sort of design you are more likely to end up in the 50-60mm range.

    I also use my compact rig as an office chair when not in use. What I found was that 50:1s cant be back driven when new, which means they will hold their motion when un-powered, but after some use they loosen up and can be back driven within the confines of my compact rig design. I now use 60:1s and they can't be back driven, even after years of use.
