My column is cracked and starting to split, is there any hope for it?
I’d contact the builder immediately.
I’ve built some very basic stringed instruments, and have done basic/relatively simple setup and repairs on violins, so I’ll give you some advice that I don’t think will harm your harp any further.
Thanks guys, contacting the builder is not an option, its a cheap pakistan pixie, but I love it.
I’d suggest patching it up with a good epoxy.
Screws across the crack might be an idea to serve double duty as clamping the crack for glue and strengthening in their own right.
