Yes but a solid, reliable connection of the axle to the an angle would be more difficult to achieve. I guess it depends on how much faith one has in their welds. That being said, the only constructive criticism I have with the above, is the metal doesn't appear to have been ground bright before the welds were made. Otherwise, it looks pretty solid and should work fine.Better to locate the axle high on the side of the angle iron to lower the whole assembly; the higher you have to raise machinery the more chance to tip it over.
Much better than pipes!
We all do from time to time , skates definitely betterBeen there, used to do that!
