I bought an old Wilton vise and was happy that I had a rehab project, but when I took it apart to clean, I saw a slight gouge in the acme screw. It looks like it has been there for 40 years. The actual metal that was gouged out was still there and it was very small. This was just something cosmetic because the bur didn't effect the threads and wasn't cracked.
What I am worried about is what is underneath the gouge near the spindle collar. At first I thought it was a weld but upon closer inspection, it looks like solder. It's a smooth ring that goes around the entire circumference.

I feel like I was duped by the Ebay seller. He said in description there were no repairs and didn't bother to mention the gouge or the solder. He said he took apart and oiled it and that this was there was "strange". You can see by the metal discoloration that the screw was heated. I contacted him but I have to pay for shipping for return which is 40 bucks. Not reasonable.
Would heating it to melt off the solder and see what's underneath. Would that hurt anything?
