Re: Mast Crane Repair
Thanks for replys.
I was considering using the epoxy metal filler, but was concerned the UV rays could degrade in a short time- could paint to protect from UV, but then it becomes a maintenace issue.
I plan to un-step the mast to replace all standing rigging and mast tangs/bolts in a few months, so with the mast down, I could have a welder do some build-up. The mast head is welded to the mast- so not removable.
I do not think the groove is structural, but I would say it is borderline, and any moore groove cutting by the topping lift, I would say, would compromise the crane structurally. I'm the kind of guy who likes to fix things once, and not have to be concerned if my repair was "good enough."
Thing I don't want to do is introduce stress risers or change aluminum metalurgy while welding, and make the problem worse than it is.
I will shimmy up the mast and post a pic sometime over the next few days.
