We have a set of semi-permanent rugby goal posts. The ground sleeve is an 3" diameter 36" deep aluminium tube set in a 30" diameter by 48" deep concrete casing. The posts (aluminium) have a 2 5/8"~ OD sleeve that slides into the sleeve. Well... the boys went to remove them for painting and the post was stuck... they ended up breaking off the post inside the pipe. I'm trying to find a way to remove the inner tube. Specifically a tool that would rip pipe lengthwise: ( my mind sees a tool with a cutting wheel similar to a tubing cutter but the wheel is on the outside... on a stick) Any ideas would be appreciated!
