A number of years ago, I heard that if you ever want to build your dream home; you will need to do it at least twice. Why, you learn things the first time and make adjustments. The same is true for this cart. Let’s take a look at the issues I was having and then determine how to fix them.
- Track clearance (Top of cross tie to bottom of cart)
- Bad seating
- Short wheelbase
- Wheel carriers weren’t the same
- Wheel carrier secured with one cotter pin (single point failure)
- Increase roll angle (better front universal joint)
- Can’t cut square holes
- Remove small bearings that prevent roll on the rear axle
Since this coaster will go upside down, we wanted to eliminate all single point failure locations like the cotter pin mentioned above. We also increased the size of all members to increase strength of the design. Result: better cart with increased safety and comfort.
