Wellā¦ As for things like that shaftā¦ Things break on carriages, itās why smart people have a decent spares kit on hand. Iāve been on back step when the shaft broke at the end and we were 15-20 minutes from home, so we just tied it up best as possible and drive the pony home at a walk. He was only a few weeks hitched and I was more worried than him or the driver/trainer!
A friend was on marathon when the telescoping tip broke, they got out of the hazard, tied it up as best as possible and finished marathon, although not at her normal blazing speed (this was WC level drivers so not stupid newbs).
My worst one could have been sooo bad but I got so lucky. My right telescoping tip holding washer came unscrewed inside the shaft and as I turned a sharp left, the tip and the shaft justā¦ parted company. And the freaking shaft dropped and stabbed the ground and almost lifted the front wheel up. Thank all the gods I had just started the drive and was still walking, and just walking right turns around some obstacles, it would have been super ugly if that had happened at any speed! Until that moment I didnāt even know it had a washer and a bolt inside the shaft. Now it has a healthy dose of thread locker on it as well as periodic tightness checks.
The point is that these things break, even with good welds and serious due diligence, even modern marathon vehicles that are part stainless steel and made for a beating. Driving isnāt a safe sport by any stretch! The fool with the wood shaft thoughā¦ #faceplant (although I wonder if it would be safe/more durable of all the cracks were thoroughly sealed up with a strong wood glue and then banded? Glue+wood is stronger than most people think (until it gets wet)ā¦ Probably not, too much stress on cart shafts compared to independent carriage shafts
