How thick? How much rebar? Are pilers necessary? Can it be poured as a solid pad?

call a local concreat company and let him know it is for a community arena and ask him for this info.  They will probably give you a general idea.

YOUR DEALING WITH SALT WATER SO A DERIVITIVE WOULD BE ANTI AGRESSION TO THIS  SOME CONCRETE COMPANIES MAY HAVE THIS TRUE ANSWER\nANTI CORROSIVE PROTECTANT \nSEE IN FLORIDA WE USED A ALUMINUM BASED METAL BUT CHECK WITH THE CONCRETE MANUFACTURES IN YOUR AREA

You will need to know the size of the mold needed... how large it the finish article... L x W and thickness..

Being a touch thick, what are key ratios?

if you're building an actual realistic model of a knee joint, that won't be easy at all since there are floating parts (patella) and such.\n\nbut anyway, you know that poplar wood is very close to the actual density and strength of human bones?  they proved it on mythbusters.  what other kind of material do you think you're going to be able to use, if you can't use wood?  it's perfect, since it can be screwed into, nailed into, glued, etc.  there will be NO suitable replacement that you can obtain easily.  for example, you could use natural nylon/delrin, which is a common plastic, which comes in 12ft long bars, ranging from .500" to 6.000" diameter.  you wont find that "around town."\n\nthe only other bone material i can think of would be clay.  shape it, then fire it to harden it.\n\nobviously, you can get rubber for tendons / ligaments.  go to either a home depot, or an arts & crafts store.  check for large rubber bands, rubber tubing, even bicycle innertubes would function.

I would  use 3/4" marine plywood. I would also seal any edges that I cut.

It's difficult to find a plywood any thicker than 3/4", hardwood or softwood. In dimensional lumber measurements, 1" is usually referred to as 5/4...but that's not plywood.  You might try WoodPlanet at www.woodplanet.com ... They have 1" thick sheets of 4'x8' hard maple plywood, A/A grade, good on both sides, which sounds like something you might be looking for.

I don't actually prefer thick pads. It feels like I have pillows in my pants. I prefer regular unless I have a heavy flow then I use super.

Everyone I've ever spoken too who got the idea into their head to make their own table have always come to the same conclusion...not worth the effort.  Pub-sized tables are cheap and readily available.  Just buy a good one from your local billiards retail store.  Cheers.  M.D.-BCA Instructor/Referee.

A rugged raft can be made by getting some styrofoam blocks and attaching them to the bottom of a plywood sheet, possibly by tying it on through holes drilled through the plywood.  You have to use a lot of strands, to avoid cutting the foam with the cord.  Closed-cell foam has the advantage of not getting waterlogged and not leaking if damaged.\n\nAccording to the amount of weight you want to carry, you should use an amount of foam which will have the same volume as an equivalent weight of water.  Say 300 pounds for one man and his equipment needs five cubic feet of foam to support him, plus extra for the deck and fittings.\n\nFor lashing a log raft like Huck Finn, see the Boy Scout Pioneering handbook for techniques.  Logs are heavy, and don't really make good floats, unless it's all you have.

the side wall on the roll cage should be 5/6 mill thick that should adsorb most of the impact that's what we use  to build land rover trailers and rock claimers it will have to be mild steel where you from\n     \nwolf4128

dependin on the floor type:\n\nWood use 1 1/2 lag bolts, with flat washers for added support. \n\nConcret use wall anchors you will need a masonery bit to make holes for the anchors\n\ntile: pay a professional, thatway if the tile get broke in the process they will have to replace it, which in the long run will prob be the least headache. i would advise you have them place a rubber gasket down to help keep the tile from being ruined from any possible movement.

Hi Mike M. I just found this question so sorry I'm just now replying. Thanks for the links. I showed my fiance the site for bid4build and he said it wasn't what he was looking for, he needs something that saves the cost of materials so it will automatically upload when he creates an estimate. Here's the site for bid4build, check it out, it may be what you are looking for. Good luck to you and thanks again! I accidentally told you it was bids4build but it's bid4build. \n\nhttp://www.bid4build.com/

i just build my snowboard box this last weekend. last year i built a 16' x 1' x 4' box and i had used plexiglass and it cracked and warped with the temperature changes, so maybe that isn't the way to go. I'm guessing you should go with treflon or perspex? or id say use the stuff from the hockey rinks which probably rang from 60$-80$. idk if i helped any.
