I have a project where I'm making dog agility weave poles using 3/4 steel pipe. The pipe is welded to strip steel and has inserts that fit inside to a fairly close tolerance.
My problem is the ridges (seams?) inside the pipe. It is about a 1/16th higher than the rest of the i.d. surface. I WANT IT GONE!
I have tried dremel, a "cone" grinder in a drill, but really need to find a good rotary grinder, or honing tool of some sort. That or a new technique.
Input will be appreciated!
