I know it's volleyball related, but not related to any of the volleyball forums, and I figured this might be a good place to ask. If there's a more proper place on volleytalk, please direct me. Or if anyone knows of other forums, for e.g., players, please point me to those too.
I'm hoping to find a good way to set up grass volleyball nets on indoor turf and in a park that doesn't allow stakes (Minneapolis new downtown park), without using stakes. And I'll be renting either the indoor facility or the park so would be bringing in whatever I use (and won't know and can't rely on tying anything to fixed features).
Has anyone does this or have suggestions ? My idea is to try a bunch of 5 gallons buckets filled with flat weights, and to tie the guidelines onto the buckets. Perhaps tires as a base ? Or course any net I've seen, e.g., in church yards, that uses tires has sagging net.
Anyway, just thought I'd ask before I go buy/try a bunch of stuff.
Thanks

In high school I remember ours were just metal poles fixed to concrete-filled tires. Something like this (although this uses a wooden post):  |

Nothing was ever padded, and I'd heard of a few times where someone ran into something like a basketball backboard support. |

I look at what my kid plays on today and there's not quite the sense of danger. Of course at that age I was allowed to walk home by myself. |

The problem is, the net can never be as tight. From an engineering perspective, the tension in the net passes a horizontal load to the poles. You need something to react those loads. An in-floor gym system reacts those loads by sideways forces of the pole against the socket it is inserted into. A net with stakes reacts those loads into tension on the guy lines (and eventually a sideways pull on the stakes).
The only thing you have to react the sideways pull of the net on those concrete blocks is by gravity on the outside edge. So really you don't want that heavy concrete right under the post. You really want it off-center, as far to the outside as possible.

Also why no stakes? I would think a set up such as this is going to damage grass a lot more on a warm day of volleyball?

There is a new downtown Minneapolis park that will rent out their space for grass volleyball (I run tournaments and do a lot of informal events with friends), but they won't allow any staking due to irrigation systems--they won't budge on this. Also, some friends and I have thought it to be interesting to rent out indoor turf places for indoor grass volleyball. Not critical to rent either place, but both would be pretty cool, and if we solve for one, we can solve for the other. There are various freestanding volleyball standards, with wheels, but they are quite expensive. I'd also have to transport these. I've seen some concrete in tire ones for sale, but they weigh a ton.

Irrigation that makes sense we have little of that here in Seattle parks

Yeah - those roll your own systems that rely on weight can't really put any tension. Actually - what we had in high school was only used indoors. Our outdoor setups were placed between poles supporting basketball backboards. We only used the tires indoors. We actually had a few high performance poles, but those were only used by the competitive teams. In PE we only got these posts.
Of course there can be some pretty tight rules. If they don't want stakes because they're using buried drip irrigation, then obviously they had rules to address it. However, I'd imagine that anything terribly heavy has the potential to damage something buried underneath too.

Anyway, just thought I'd ask before I go buy/try a bunch of stuff. Thanks Contact a club that does qualifiers. They have 100s of courts set up without any in-ground system (there are no holes in conv center floors). There are a few companies that do this. You wouldn't need the sport court rental, just the standards and nets. |

You really want it off-center, as far to the outside as possible. We did a test event with one net and it worked out quite well. Just used a regular grass net, but hooked each guidline onto a strap that was wrapped around two sand bags (one sand bag was not quite enough weight).  |

Hi ndodge,
Did you wind up having success with this set up? I'm having the same issue with Parks and Rec in So Cal. We'd need a set up for youth volleyball. Does it hold up well and do you have any tips? Thanks!
