i've built/made about 8 of them. took a piece of mild steel flat bar formed the chisled head by grinding the angle. had it hardened then took 1 1/2 or 2 inch pipe. cut out a slot for the flat bar fit it, welded it up. then took a plumbing end cap, steel, welded that to the pipe, then took a big washer, ground it to fit the end cap, welded it to end cap, then tied a rope to it.

Real decision is how much space is needed. Frabill is 6'6"x 6'6", Shappell is 7'6"x 7'6", Eskimo 949i ($289 Amazon & L&M free ship) is 8' x 8'. Find a spot in your home to tape off each hub size than cut 6ea paper circles to hole size and place on floor 3 people fishing. Mark door area on tape put all the gear the 3 people will use fishing, chairs, heater, rod case, coolers, minnow bucket tackle boxes coats etc and place inside marked floor. You will soon answer the question of which one to buy.
