I'd grind it out and weld it, have done similar to axes and hatchets over the years.A little side-step from the varmint & excavation talk:
I have a pretty old offset-head hatchet that's been my go-to for debarking my firewood. It probably had a crack in the head when I bought it but I've just noticed it more recently. I feel like this is so old that trying to weld it back together will be a fool's errand.
I'd appreciate your thoughts
even if it was it wouldn't have been very accurate or lasted very long. There are quite a few short comings in 3d printing parts that see excessive heat and pressure. One of the many reasons I haven't bothered to attempt it myself.They said the gun was a 3d printer job.
