Hi,
I'm balloon artist and I'm using the popular ZÜCA sports cart for my linetwisting setup. The little inline-skater wheels are not got for every terrain, so in the sake for better dragging stability I've converted my cart in to a big wheel cart - here is my take on it.
Bill of Material for rear axle mount:
3D printed | |
|---|---|
1x rear axle mount left | |
1x rear axle mout right | |
hardware store | |
1x M12 threaded rod, length 440mm (--> axle) | |
1x tube, length 185mm, fits over M12 rod | |
4x M8x40, six-head screw | |
4x M8 self-locking nut | |
4x M8 washer | |
4x M5x40, six-head screw | |
4x M5 self-locking nut | |
2x M5 washer | |
other store | |
2x big wheels | |
2x fastening for the wheels |
Bill of Material for the big feets:
3D printed | |
|---|---|
2x arche | |
hardware store | |
2x square tube 25x25 (outer measurment), lenght: max 120mm, | |
2x M6x45, six-head screw | |
2x M6x40, six-head screw | |
2x M6x20, six-head screw | |
6x M6 self-locking nut | |
6x M6 washer |
Installation of the big wheels:
The conversion to big wheels is straight forward - no holes have to be drilled, we use the existing ones in the frame:
Uninstall the two small wheels on each side (also the smaler screw 'between' them). Remove the two outermost screws on the lower back side (the handle is attached to them)
attache on each side a axle mount and install it (see photos)
insert the tube in between the mounts and slide the axel through the mounts an the tube, but washers on the axle
install the wheels
Installation of the big feet:
This coversion is a little more immersive and needs more preperation and hard work
Deinstall the plastic foot
Insert one of the feet in the place where the plastic was. Put it even with the rim and the bottom. At the position of the deinstalled screw mark the area on the the foot, where to drill a hole through it.
Drill the hole through the foot and loosely install it to the frame. Take one arche and put it flat on the outer bottom and flat to the feet (the side of the arch with one whole). Align the arch with the foot and mark the spot on the foot (through the whole on the arch) were to drill through the foot.
Drill through the foot and loosely attach the arch to the foot. So the foot is now fasten to the cart frame, as well to the foot.
Aligh the foot on the cart frame and mark the spot (through the arch) where you have drill the bottom. I've only marked the outer whole (the inner hole is not needed).
Drill the hole and fasten now all three scres of the foot - congrats you installed one foot
Repeat the steps for the other foot.
Notes:
depending on your choice of wheel, you have to change the diameter of your axle
depending on the diameter of the wheel you have to change the height of your feet. As rule of the thumb: max. height of the foot = (diameter of the wheel*0,5 - 30mm
I've ordered the original wheel and knobs from ZÜCA, this saved me a lot of time and I hope the spare part availability in the future will not be a big hassle.
There there are cheaper alternative out there (e.g, tires from small children bikes), feel free to remix it.
I hope you have fun with it and leave me a like! Sharing is Caring!
