seat tube deformation
The seat tube on the bike I'm working on has a very slight bulge where I jammed a screwdriver down in there to pull away the seat post. Just wanted ask what you guys thought about potential safety implications.

Since you know it's not perfect, the only implication to safety will be if you don't look at it every so often to see if it's becoming a problem.
Being a steel tube, I wouldn't worry too much about it if at all. But I would look at it every now and then.

Honestly that's fair. Not my proudest moment, but frustration got the better of me.

I might speculate that maybe tubes also get bulged by seat posts that are slightly too small a diameter for the seat tube and they rock back and forth in the clamp constantly hammering on the inside of the tube. The shorter the seat post remaining in the tube the more force to bend the tube with.
I still can't imagine how you got a screwdriver that far down between the tube and post. Or was the post completely below the top of the tube?

I posted this in another thread but here's a picture of the seat post.

Zero safety implications. And figure if you hadn't gotten the post out the frame was garbage anyways.
If it bothers you it might be possible to get the defect out with some blocks as is often done with larger dents. If it were me, though, I would be happy the post was out and ride it without worry.
