Is it chrome or straight stainless steel, cause if it’s not chromed, you could also find a machinist in the area, they should be able to put it in a machine lathe and actually put a knurl on it, or if your good with a dremel and you have a good wheel you could do a light cross cut then like buff it out to take the rough cut off, but as far as welding you should be able to, it just needs to be filed down to the metal if it’s chromed,
