Just what I wanted, a simple roller than is easy to use (It will not get frequent usage) and appears substantial.
One tip, one critisism:-
Tip - squirt some grease into the bearing area of the roller before assembly - less pushing required.
Critisism- Assembly is via 6 machine screws, thats fine , but only 6 washers are provided, it really needs another 6 (get some with a 8mm hole)
Tools required - 10mm spanner, flat blade screwdriver (not crosshead - hurrah!)
Fill with what you like via an approx 1" hole in the drum, I used water but you can use sand, cement, depending on what you want.
