I made mine light weight without a chain at the top.
1" pipe 20" long threaded on both ends.
Cap with eye bolt on one end. Small hole to side for air/water vent
1" X 2" reducer on the other end.
2" washer welded to the reducer. Holes drilled along edge of washer (like a clock) 12-6, 2-8, 4-10.
1/8X2X24" spring steel for umbrella frame. Holes have to be stamped or cut with a torch.
2 links of chain bolted to the washer. Anchor rope tied to chain link, zip tied to eyebolt.
Can add different lengths of 1" bar in the pipe for more weight.
