So I'm back working on the bench once again. I struggled with what to do with the top of the bench long enough...it's time to decide whether to remove the mill scale or not.
I decided that I'd prefer a raw steel top...so the mill scale had to go. For those not familiar with the process...it does NOT come off easily. So I broke out the big guns...a half gallon of muratic acid.
You can see the marks in this first picture where I unsuccessfully tried to remove it with a brand new flap disc.
This was after the first round of acid was neutralized...
Decided I needed to get it out of the sun and leave the acid on longer. Getting there...
4th times a charm... Cleaned up pretty good with a flap disc...now ready to weld to the base.
