Bead breaker was just from e-bay cost around £30. All I did was change the central threaded bar to m18 (supplied one is m12) and added a couple of m18 nuts to hold it in place once I'd drilled the hole in the frame to suit the bar.
Also made a ply wood spacer and handle with another m18 nut secured in it.
I made the mojo bar from a piece of 55x35mm beech. The nylon ends came from another e-bay seller.
I tapped and epoxied a length of m12 threaded rod into one end of the beech, I then epoxied the nylon tyre removal part to the threaded rod.
Once the bead is broken and the removal part is inserted under the bead its a simple case of levering the tyre off working around the m18 rod in a circle motion.
I slip a piece of plastic tube over the m18 rod to stop the beech from getting chewed up on the m18 rod.
The other end of the mojo bar is for getting the tyre back on. I used a piece of 5mm aluminium which I cut and bent to shape then a few nuts and bolts to hold it all together.
When it comes to fitting the new tyre I use plenty of lube and just push the first bead over by hand, then insert a plywood wedge to hold the second bead in the drop center of the wheel, insert the mojo bar and work the mojo bar around the tyre using plenty of lube and moving the wedge as you go.
Better look at the end of the mojo bar. any part that touches the wheel is made from nylon so no chance of getting a scratch.
Once the tyre is on I use a compressor to pop the bead and its onto the wheel balancer.
Again made from plywood, I bought the cones, rod and bearings from e-bay around £12-15.
loads of videos on youtube showing how to balance wheels its pretty straight forward.
job done
