G'day CyberJack,
looks like I have another supporter in this polarizing project of mine. Glad you think it's cool.
That's a great story of your father using it like a train and really demonstrated how sturdily they are built.
Regarding my contraption, I was going to replace the wheels with a set of the worst ones I could find, only to discover all but the front left one have a hairline crack along the shaft of the wheel which house the bearings. I have left them on and removed the only good one and replaced it with an old one with a radial crack in the tyre running from the white plastic rim ask the way out. It still works fine for this task. Now ready to use and abuse with impunity.
PS: I added pics of a wheel I was going to fit but painted first to disguise its wear, only to discover the faults with the existing wheels.
