    Cheers Mike. I think i'll probably go for nylon wheels and give them a go. A decent sized bearing would probably help too.

    There's 3 things missing in the pics with the shafts.
    Obviously the lever. The lever will be welded to the large round steel collars. They are held to the flat spots in the shaft with 4 x 8mm grub screws. If they twist out, there's no hope. The gearbox will break before they come unseated.

    And the last thing is a 4mm interference fit pin which will be pressed through the hole in the gearbox hollow shaft, and through the solid shaft out the other side.

    If you're wondering what the small side of the shaft is. That's a 6mm shaft for the flex coupler to bolt to which will join onto the potentiometer.

    P.S. yes they could probably be made to order if someone wanted a set. I'll try my best to finish these and test them first though.

    I am pretty sure @Nick Moxley recommends industrial castors rated at 2-3 times the weight of the rig, as he had longer term durability problems with in-line skate wheels.

    Inline skate wheels are designed with grip in mind so they would be designed to be a little softer than I'd like.

    F me that Motor shaft looks Pimp.


    Correct on the castor's....Skate wheels are Far too soft and will develop "flat spots" in no time. I suggest something Hard for the wheel's themselves.


    These are the wheels i currently have on, They are rather hard on the wheel material but given enough time and even these wheels developed a bit of a flat spot.

    they are from the "eliminator series" as seen here.

    I'm swaying towards polypropylene wheels. Each wheel is rated at over 120Kgs so it's more than capable of the weight. And they're cheap at only $5 usd or less each so even if I do break them or they show wear I can easily replace them with something better.

    Here's what I'm going for:
    https://www.technicawheels.co.uk/search-results?LucSearch_ItemType=CASTOR&searchQuery=P5256

    Combined load capacity of over 500Kgs. I think they should probably work. The only thing I don't like about them is the height of 105mm but I can't seem to find anything smaller with the same kind of weight ratings.

    What are you planning to run the wheels on ? Plate of steel ?

    Yes I think 5mm steel should be good. And I have a large sheet of it to use up as well.

    Those look like non-bearing casters. I would look for something with bearings.

    @shannonb1 is absolutely correct about the necessity for bearings in the castors. For me it was the difference between the sim moving and not.

    I noticed that but I decided to give them a try. They should be here on friday. My theory behind then is that if they bust I can use the brackets and stick some wheels with bearings into them. I plan to use all 4 in a row so it should spread all the weight a bit. Fingers crossed.

    Hrmm, darn didn't notice that the first time i looked at them. Oh well, its not like they were very expensive. Lesson learned if they aren't up to the task.

    It would have been nice to have wheels with bearings but any that were small enough didn't come with the bracket attached, and any that had a bracket were massive. So basically what i've done is bought some heavy duty brackets with some free wheels to try out. I have a feeling they might actually be fine.

    I modified the Frame on my Castors to suite the job, And yes, smaller than 2-3" you will struggle to find a caster that will have enough weight capacity And bearings. Again like you said, Its not like you spend a Bunch of $$ on them, So if they dont work you can always upgrade to better.

    Car mechanics mostly last night but the tabs for the shoulder mounts have been cut and hopefully I'll get the remains of the welding all done this weekend.

    I also need to cut wood and mount the lazy susan at the front. Loads of work to do now to try and finish most of the hardware work before I can start on the electronics wiring.

    These are actually surprisingly solid. They're also more free running and smooth than i thought they would be.
