I just made a set of sheaf towers for practice and a possible game here in sitka. In all the supplies cost about $150 dollars. They only reach 30ft but that is plenty for practice and the small game I am trying to start. I posted picks and a parts list with about rounded cost. This is Alaska so in the lowere 48 you can probably get a lot of this stuff cheaper. Parts List 2 20ft 2"x6" boards $21 2 heavy duty 12ft extendable poles $40 4 1in lag bolt eyelets $6 6 1/2in eyelets $6 6 1in metal conduit securing bands $6 1 10ft length of 1" PVC pipe $5 3 100ft 100lb lengths of rope $40 1 100ft 50lb length of rope $15 2 pulleys $4 8 2ft Rebar stakes $15 Total $158 How to build |

Directions Bottom of 20ft board Take two 1in eyelets and screw them into the base of the board with top eyelet about 8in from bottom of board and bottom eyelet 4in below the top. This will be placed over the anchor stake at the base of the upright. Top of board. Screw 3 1/2in eyelets into the top of each board. These will be the anchors for the Guide lines. Tie 50ft lengths of rope to each eyelet. On opposite side of the top of board use 3 metal conduit securing bands to attach telescoping pole extensions with 1 & 1/2ft overlap of the board. In the pictures above the poles are pointing the opposite direction they would be when the uprights are put up. Attach the pulleys to the top of the poles and attach the cross bar with two lengths of 50ft rope. I'll post a pic of the whole thing up when I get a chance. ------------- |

Here is one of the uprights. it's pretty solid. ------------- |

I made a pair of these from two pieces of ten foot, 2-inch galvanized electrical conduit, joined with a standard conduit joiner, plus a 10-foot piece of 1-inch conduit that slid into the top of the upper piece of 2-inch. couple of hose clamps, D-rings, guy ropes, eye bolts and cheap pulleys, and I had me a pair of 28-foot Sheaf standards for about $65. ------------- Alan Hebert Geezer-In-Training |

with the three guy cables in the pic, how do you move the bar? wouldn't it hang up going past the point where the eyebolts are? ------------- --------- I have very few social interaction skills, so I just throw stuff instead. |

On my setup I only use 2 guy ropes. Instead of a third guy rope, I have a rope/wire at about 13 1/2 feet that connects the two uprights to each other. So, if you were looking at it from above, the ropes would make a "Y" shape. The "base" of the "Y" is the rope/wire that connects one upright to the other. The two branches of the "Y" are the guy ropes. Upside to this is that there are no guy ropes anywhere near the front of the throwing area...and the guy ropes are short, about 20 feet. Downside is that opening height has to be above the rope/wire that connects the two uprights to each other... that means 14 feet on my setup. 14 feet can be a problem for smallish, beginning sheaf throwers. Then again, if you're at all tight on time, starting out at 14+ feet will thin the field of the complete newbs in one round and you'll finish the event more quickly. For new folks, I just move them over to my "extra" WOB standards, which are also electrical conduit, but only go up to 15 feet. Since they're short, I don't use guy ropes, I just drive two big steel fence stakes into the ground where each pole goes, and duct tape them to the uprights. ------------- Alan Hebert Geezer-In-Training |

That was my first thought on making a pair. My plan was to start with 2in conduit in ten foot sections and move down the diameter as i went higher. I priced it all out and on the Island I live here in alaska it would have cost me about $300+ to get it done. So I went with this direction. As for the guy ropes no they won't get caught as long as your standards are set slightly wider than the horizontal bar. ------------- |

But can you break it down to fit into a "Flat Rate" box? ------------- Spencer Tyler = Awesome!!! |
