    Little tip for measuring bump steer (and other steering characteristics). Cable tie a laser pointer onto the hub, aiming at a piece of paper on the wall behind, or in front, and draw its position. Move the hub through the motion you need, up and down in the case of bump steer, and mark the positions for that too. Then using a plum line you can measure how far the laser position is moving on the paper and with a bit of trig, calculate the angle of bump steer.

      Exactly.. Those extra sprockets that you put on the PULL side of the chain need to be much stronger with heavy bearings just like the carrier. The tensioner sprocket on the slop (return) side of the chain doesn't really get any pressure (until you go in reverse). Those tension/ idle sprockets on the pull side of the chain are going to break -- just be warned.

    Chris, cool steering. As a thought, you could disassemble that rack and pinion steering box and see how it’s designed. I think you’d enjoy building your own rack for future projects. The other advantage to doing so is that the inner tie rod ends could be perfectly aligned with the a-arm pivot points, to minimize bumpsteer.

    Love the progress! As long as the steering rack is centered, the bumpsteer looks good since the pivots on the tie rods are in line with the suspension a-arm mounting points. It isn't until you lock the steering one way or the other that you'll see the bumps steer creep in...always a compromise.

  • @bradley3549
    @bradley3549 Рік тому +1

    The reason you probably thought the steering had to be being he front axle is because it's a lot easier to get proper ackerman due to clearance with the wheels. If you put it in front the axle, the steering arms want to be outboard of the steering pivot axis, which generally is also where the wheel wants to be.

  • @JokerInk-CustomBuilds
    @JokerInk-CustomBuilds Рік тому

    9:50 by having the rack and pinion infront of the fron axle centerline you risk making the steering geometry wrong. It is called the Ackerman Geometry; Your outside frontwheel ends up turning sharper than the inside wheel when steering.... to avoid this you need to get the steering knuckles on the outside of an imaginary line going from the center of the rear axles through the turning point on the front steering.... wich is not easy.
    This problem was actually something old hot rodders used to battle whne building hotrods with the steering rod infront of the front axles... I had to learn it from hotrodder forums to apply it on my RC hotrod builds to make them steer better! LOL
    edit: 14:59 You mention the ackerman, so I guess you know what to look out for! :D

  • @anomamos9095
    @anomamos9095 Рік тому +1

    Tips
    You can make a chain drive differential out of a car diff.
    You don’t need to put a rack and pinion in exactly the right place, you can put it almost anywhere near enough.
    Methods.
    Get the centre out of the diff and remove the crown wheel and replace with a chain sprocket.
    Make a removable can to cover the spider gears so you can pack them with grease.
    Create a mount to hold The bearings and mont the diff to the frame. If you are a bit creative you may add a locker mechanism.
    Steering
    Place the rack in a higher position than the place it would need to be to avoid bump steer etc.
    You will be creating a solid rod between each wheel in a similar setup to old style steering box and idler arms
    Run a bar parallel to the rack and pinion no more than 50 mm away from it but still clearing the bots and such , connect the tie rod ends coming out of the rack to this bar. You can now depending on how far away the bar is from the proper position connect it to the wheels for steering or by using ball joints and an idler arm to prevent flopping attach it to the steering through another link rod.
    This method can be used on lifted trucks.

  • @BigIronTexas
    @BigIronTexas Рік тому

    as long as the steering rack is consistent on the Z axis there should be no issue with putting longer steering arms on the front wheel assembly. for example, imagine the tab that the heim joint attaches to about 8 inches long and boxes in. seems like that would allow enough room for everything and still allow for proper alignment. in fact, if you make those tabs a bit longer your tiny bit of bump steer will completely go away.

    Glad your going with EPS on this rig, you will definitely need it. I wonder what options you have to reduce chain noise?
    I still would like to see doors on this project though! lol
    I think you might find that you’ll need to raise the rear end quite a bit to keep it off the ground when climbing hills, but that’s just an observation and could be wrong.
    Looking great man

      I think using alot of that Plastic cutting board material (can't remember what it's called) for chain sliders, it's would be longer lasting than delron material 🤔
