Our old core box finally gave out halfway through a big pour yesterday

It was a steel frame box we've had for about eight years, and the hinge just snapped clean off when we were setting up for a batch of 50 manhole covers. I had to grab some scrap angle iron and a welder to make a quick fix so we could finish the job. What's the longest you've kept a core box in service before it needed a real repair?

Eight years is a solid run for a steel frame. I had a plywood box that made it almost a decade before the sides just started to delaminate from all the moisture. My quick fix was to screw on some aluminum corner braces from the hardware store, which bought me another two seasons. Sometimes a simple patch job is all you need to keep a good box going.

Is it really that impressive though? I mean, eight years for a steel frame sounds like bare minimum to me, not some kind of milestone. @the_dylan I know you're impressed but I think we set the bar too low for these things. Any frame that can't handle regular use for at least a decade without falling apart isn't built right in my book. I've got an old aluminum frame from the 90s that's still going strong, so eight years doesn't seem like anything to brag about.

That steel frame lasted a good eight years, though.
