Hi, I work in a small shop (4 of us). We build temporary fence panels that we rent out for job sites and events. We build the panels, the bases, and the tops ourselves. After we weld everything up, we send it all out to be galvanized. Where we have problems is cleaning both the posts on the bases and the interior of the square tube on the panels to a depth of approx. 12 inches. We are sticking a round peg in a square hole so we need both the round peg and the square hole to be as smooth as possible.

Right now we use a reciprocating saw to clean the inside of the square tube, both the extra galvanizing and the seam. And we use a flap disc to clean the outside of the round posts. This method is fine if you just have a few to clean. However, this situation is not optimal when you are dealing with thousands of posts and tubes.

I am hoping by tapping into the collective experience of this forum I can find some type of tool, either purchases or made, that will make these processes much easier.

The round posts originally start as 1" schedule 40 pipe and the square tube starts as 1 1/8 14 gauge square tube.
