Dented Steel Frame
Reaching out to the bicycle community for some suggestions. Here is an old Centurion bicycle frame that might date back from 77 that's what I am gathering from the bottom of the serial code. The frame is steel. What you are seeing is where a kickstand use to take place there and over time whomever had owned the bicycle previous kept on tightening the hole and little by little crushed the bottom of the frame. I was checking to see if there were any cracks and there are none. I really want to save this bicycle and turn it into a fixed gear but in the process don't want to buy parts and let the frame crap out on me. I was thinking just as an idea to have the bottom of the frame be re welded. Any help would be much appreciated.
Kindest Regards,
Jesse

Clean it up, get some fresh primer & paint on it & ride it.
Check it periodically to see if any cracks develop.

Common occurrence. Look at the dimples on the driveside of the bike made for chainring clearance. A little flattening of the chainstays from an overzealous mechanic won't hurt anything.

The dents don't matter at all, but the depth of the rust might. I test these by probing with an ice pick. Scratch away to get a sense of the depth, and end by trying to push the pick through the thinnest place. Don't try to drive the pick through, just lean on it a bit.

JesseMN, Very likely it'll be fine as long as there are no sharp creases. On my current build I had to make the very same judgement call, which I hope is correct.
