Did you close up the end of the tubes? I'm guessing so, otherwise they'll fill up with dirt and rust out right?
What size bolts did you use to bolt them in the bucket?
Add this to the list of things I gotta build / do.
Yeah of course the tips are sealed up. I welded a small piece to seal them up and the ground them smooth. I can't remember the bolt size. I think they were grade 8 and 7/16".
