The local gym has decided that they will let me put up some sport routes in the gym. This is great but there is a problem...the wall is made of plywood. I think the biggest problem is going to be distributing the force so it doesn't rip out the plywood. Is there any way to make the bolts safe enough to take a lead fall on?

are you talking about the gym letting you install the actual bolts, or just a route? If it's the bolts then... DO NOT INSTALL THEM ON A T-NUT In order to use a bolt on a plywood wall, you need to have a "plate" backing. Typically its a 2 sqr foot steel plate that screws onto the plywood supports (not the plywood sheet) I don't know where you can find one, my gym just made their own.
good luck

we used a static rope at our local.
secure the rope in behind the route - tied in at top first, then tie loops where you want the bolts, tie in at bottom, very tight.
drill holes through the plywood big enough for a sling to fit, then tie slings to the loops and stuff through the holes to the front. you can either just leave biners on the webbing or could clip draws into the webbing.
hopefully you can access the back of the plywood, or this is all moot.

you cant put bolts on the plywood, as was previously stated. but you can drill them int whatever is used to support plywood (like wooden beams, concrete...) if its strong enough.

Another way that works fairly well is to use long bolts on the hangers. Attach the bolts to a 2*6 or bigger which is attached to the main support studs at the back of the wall. Run the bold through the 2*6 straight back from the hanger and place a large washer with a nut on the back side of the 2*6. This distributes the load over the support structure of the wall and does not require any metal plates or ropework. Sorry if that was confusing. I'm tired and going to bed now! :)
