    Maybe something along this type of design....

    @RandomCoder this is pretty...but I should try to find something better adaptable to aluminium profiles...I don't know :)

    I know you are concerned about weight. I don't have scales but weight wise I checked tonight and I can pick up my complete wheel and pedal mount assembly with my little finger

    ahahha sincerely, I love you noorbeast!

    Well, I think with your last message you give to me the confirm that my structure of pedal and steering wheel it's really too much heighs.. As I said, I am struggling to hold it suspended with one hand. Don't you think so? :)

    This weekend I will reproject it, and I will buy profile 30x30, wich are half of weight (and 1/3 of Inertia, so less resistant), and I will make pedal frame like yours (so 45x45x1,5mm of aluminium plate and 40x40x4mm angles).

    Really, I will like to give an angle to my pedal's plate, but i'm out of ideas in this moment..bah, I need something resistant and adaptable to my aluminium profiles.

    Hi @mirkobastianini
    You've slightly missed my point. I wasn't suggesting to buy and adapt the bracket that I linked, but rather use the same principle with your aluminium extrusion. Just fit index plungers to locate into pre-drilled holes allowing you to easily set the pedal plate angle as required.

    Ok RandomCoder, sorry :)
    Do you have any idea to how I can make this in detail? Consider that at this moment I have a profile like this...
    http://www.motedis.it/shop/Profilat...nio-30x30-scanalatura-8-tipo-B::99999432.html

    There are a lot of accessories for this kind of profiles, here:
    http://www.motedis.it/shop/Accessor...30-scanalatura-8-tipo-B:::9999916_999997.html

    Sorry for my "noobness", but i'm not good in mechanic, and I'm like a child to discover good solution in this field.

    @mirkobastianini I'm still learning to use SketchUp but here is what I had in mind if wanting to keep with the central pivot you already have....
    [​IMG]
    And from another perspective....
    [​IMG]
    I've not shown the locking pin in the diagram but for this I was thinking of something very quick and convenient like an index plunger...
    [​IMG]

    This design is more easily achieved if using an aluminium channel at each side of the pedal plate as shown in one of the previous posts. But hopefully you can see from the above that it is still possible to achieve if using a central strut and pivot.

    First of all, thank you so much @RandomCoder for time that you have spent of doing this. I really appreciated it.

    Now It's more clear and it's a very good solution! Maybe , as you said, it's better to use a plate on each side of the aluminium profile...this can garanteed me to make only one trasversal hole and I think it's a more resistant solution instead of only one central point... don't you think so? Anyway, a general question, do you think it's enough resistant, right?

    Now I must find something that can be shipped here in italy and can be easily adaptable to my 30x30 aluminium profile...maybe, if I can find only on motedis.com, it's better... If you have some links, please share :)

    This weekend I want to redesign and order all pieces, thanks to lovely suggestion of noorbeast and RandomCoder.. <3

    Uff... this weekend passed away and I haven't worked to my simulator (i've changed my room...my house wants my blood :D), So in this incoming week I will try to make the order for 30x30 profiles.

    Anyway, I think this night I've found a beautiful piece that can be very useful for give a angle to pedal plate...this is the piece:
    http://www.motedis.it/shop/Accessor...serie-20-30-tagliata-al-laser::999993849.html

    And this is the working video:

    what do you think @RandomCoder and @noorbeast ?;)

    Anyway, talking about something else, what do you think about my idea (photo attached at this post) to make base for steering wheel and pedal adaptable to different heights? It's a good choice? Because I don't how much this solution can be resistant.

    Or I can think to something different with this plate (I attach links) ?

    I like the height adjuster but I'm not so sure about the pedal angle bracket. Would it give enough angle adjustment and could you secure it tight enough with wing nuts or thumb screws as I'm guessing that you wouldn't want to use Allen keys each time to adjust the angle.

    Little bit update... today i've received Universal joint (it's very beautiful <3) and I've made the base for it. The measure of joint's base are 10cmx10cmx35cm. The pivot is 7,5cm, so the overall height is 42,5 cm.

    Now, while I'm waiting my orders to remake the structure for pedal and steering wheel, I can think about electronics part and motors... So, I ask your help.

    It's possible to have a design like the photo called "Immagine" in this post? I know that it's not in scale (in fact i've written measures on an existed photo finded on this forum). If I can, I want to place motor little back under the seat, and use the holes of seat. Anyway, I don't know nothing about CTC, levers, optimal angles, ecc, so if anybody can give to me any help or advice, or sintetic guide, i'm really happy :)

    For now, I'm sure that I want to use 2 JRK, so if somebody has advice about motors, it's appreciated

    Ok...where I can find optimal values that I should have for my sim?

    The answer depends on the load you want to drive, the motor capacity and the design dimensions.

    So the optimal values are enough torque to drive your design at a reasonable linear speed for a given load.

    Thanks @noorbeast for this generic but good answer.

    Cause i'm a noob on this, can you (or other on this forum) give me some advices of what I should make and buy? I'm fully opened to accept any suggestion for what kind of motors I should use, what kind of CTC and levers... I think you know what kind of design I want to achieve (it's like your simulator :D ). The only difference on your simulator is that I want to try (correct me if I had a bad idea) to connect levers on the photo I've inserted here (I have a overall height about 42cm, and I can give a good angle to levers cause my base is 60cm)

    The only constraint I have is I want to use 2 JRK ;)

    Ok, so if I have understand well the situation, for my sim I need:

    - 2 motors like 50:1,60:1
    - 2 JRK for moving this motors
    - 2 Power supply (I will think about it later)
    - 2 potentiometer (I want to use Hall sensors)
    - 2 lever from motors to seat

    So if i'm right...let's start step by step. What do you think about this motors?. Seems like @noorbeast 's motors...seems good for JRK (15A nominal, 30 peak), and are 62:1, 135W... but maybe they are too fast ?(3700 loaded). Here the datasheet and link (select second option on the site to see this motor)..
    https://www.motioncontrolproducts.co.uk/productimages/cms/PDF/GH1436.pdf
    https://www.motioncontrolproducts.co.uk/products/8/166/dc-brushed-geared-motor-73zyt-120w-135w/

    Please be sincere with me, If they can be good or no for simulator..thanks :)

    Regarding potentiometer...I want to use Hall sensor. I'm thinking to use @Zed pot..Zed, where is your thread? I can't find it. Can you provide to me some more information about this potentiometer? Are good enough? How can i connect them to motors? :)

    And... what other things I need to connect motor to seat? ;)
