78.57 square metres of what?
We're doing a little trials muck around/demo at the Woodford Folk Festival at the end of the year and I've been thinking about what to use. So far I've come up with lots of sandwich boards, a launch ramp, planks of varying skinniness, and different boxes to hop on and gap between. The thing is it needs to be easily transportable. Are there any other common trials things that I've missed that will be appropriate? I was also thinking of a metal ladded of sorts (made for the purpose of trials) that is solid and not too heavy. That way you could hop either between or on top of the round (and small) metal rungs. Any suggestions?

I've thought of a few little combinations of things that gnereally wouldn't be too hard to transport. I'll attach a diagram of the basic layout I was thinking of. My only real concern now is those big boxes. What can we make them out of? They need to be light yet as solid and stable as possible and preferably at least partially collapsable. Am I just dreaming here or does such a think exist?

andrew_carter How did you come to the shorter folded up position? By pulling the hinge pins out on two opposite corners. You then have two sets of folded pairs of sides. (in the diagram note the black vs hollow hinge pivots) I think I'd have trouble trusting the strength of the middle of the top part of that box. Any ideas for supporting it when it's being jumped around on? Good point, particularly if for larger boxes (say greater than 2? feet on a side) and/or if the user is going to be doing high hops while on top. The top could be cross brace, or one could use thicker plywood or multiple layers of plywood, or internal 'X' cross braces could be used. Internal 'X' braces could be made collapsable by slotting each of two pieces in the center so they fit together standing on edge in an X (like water bed supports are (or were)). Have you got some sort of performance coming up soon? Nope. Just for fun. Might use them at the Austin JuggleFest come February. -- duaner - - ------------------------------------------------------------------------ duaner's Profile: http://www.unicyclist.com/profile/4297 View this thread: http://www.unicyclist.com/thread/27894 |

It might make it a bit more difficult, but looking at the first picture the boxes don't really need to be boxes. You only really need a top. How about making a table instead, a flat piece of wood with X reinforcement for the top. Then four legs. You could make the four legs splay out slightly away from the corners of the square top, which would give you stability and have crosses of strong wire making an X between each pair of legs to stop them being pulled out too much. If they're bolted on to the top then you could fully dismantle it down to the top piece plus legs & wires.

Sofa, Those are meant to be bits of wood, not strings. That way, they would hopefully make it more stable by opposing the 'push' not the 'pull'. I don't know if that makes any sense but it seems like it would be stronger...unless you had heaps of strings. Duaner, That makes sense. I just didn't realise you could pull the pins out of hinges. X bracing seems like the way to go. Do you think the actual braces would have to be resting on the upright walls of the box? That might actually help to keep things stable as well as solid. You could cut grooves in the bracing where it sits on the upright parts so it wouldn't slide around when gapping onto and from it. Joe, That sounds like a really good idea. Just to make sure, would it look something like in this diagram? Do the wires connect at the top to the horizontal board or to tops of the supporting legs? How would you fasten the wire?

I thought of something last night...why not use a mini trampoline in trials demos? It'd be great fun! I drew a diagram of a minitramp. next to a 2m high platform.

That way you could hop either between or on top of the round (and small) metal rungs. Any suggestions? Andrew * Those are pretty cool diagrams. Maybe a couple of suggestions might be helpful: Re sandwich boards: Sandwich boards are great- you could do a complete demo with nothing else I think. 5/8" or ideally 3/4" thick plywood is best for making them. Sandwich boards look a more attractive and are stronger if you put the 2x4s on the inside rather than the outside, and then attach the hinge to the 2x4's. This also seems to be a bit more durable for moves like pedal grabs onto the end of a sandwich boards. It's really, really important that sandwich boards be significantly wider than they are tall, and be hinged quite wide open, or they can be pretty lethal for tipping over. I'd say half again as wide as they are tall, at least, and maybe at least 35 degrees open. For the highest ones (ie higher than say 3 feet) it's best if the top edge of the board is narrower than the bottom, making a more stable pyramid shape. It's good idea to hollow out the middle part of the edge that touches the ground, because this makes them much more stable on grass. Rails: You should be able to make rails that nest in the groove on sandwich boards, either round poles or square rails. This is convenient and easily transportable, and can be quite stable. This is a great place to put round rails if you want them. Vertical poles: At the last UNICON we made a platform for a vertical pole by making a pyramid-shaped box, with a wide 30"x30" bottom and a flat 10"x10" top. In the top we cut an 8" diameter hole and stuck an 8" wide round wooden pole down inside. The pole was secured at the bottom by two boards that attached to either side of the inside of the pyramid box. One other major factor is that the pole has to extend sufficiently far above the highest support that the supports will not interfere with the bottom of the tire when doing pedal grabs. Drop transitions: It's really nice to have a strong, curved transition for drops, shaped like the kicker that trials bikers would use to get onto something. This really saves impact force on your cranks. In the Norco demos I usually drop off an 8' high trailer onto a 2' transition, and it's less force on the body than droping 3' to flat ground. Other comments: Smooth surfaces on boxes and ladders are usually much better than any kind of ladder bridge setup, because the crowd can't tell why a rough surface is harder, and it just makes things look more awkward. Parallel beams set up between two 4'x4'x24" boxes work well for lots of different tricks. Make the top of the beams flush with the boxes so that there is no little bump to trip you up when gliding or wheel walking along the beam. It's better to make lots of independent, mobile structures than to think in terms of making longer lines that can only be set up in a couple of different ways. If you don't want the complexity of collapsible boxes, make boxes that can nest inside each other to save space.

duaner wrote: *Box Portability, idea 2: use hinges on vertical box corners, and make the top removable. Note: To collapse completely as shown in the diagrams, at least one pair of diagonally opposite hinges must be offset vertically (otherwise they will get in each others way while collapsed). The top of the box is not in the diagrams, only the sides. top = top view of setup box right=box collapsed (flatter and longer) bottom=box collaped (shorter but less flat). One pair of opposite hinges have the pins removed to collapse in two pieces like this * In the old Norco Trials Team setup, we had one larger box that could be dismantled. Basically we made it like all the other boxes, that is with plywood and 2x2's along the edge of each plywood such that they could be put together. However, instead of screwing the plywood together we used bolts and T-nuts (nuts that can be hammered into a hole, to form a tapped hole you can screw bolts into). This was simple and worked well. We also put a door in the side of it so that we could store our stuff inside during demos. -- danger_uni - Kris Holm ------------------------------------------------------------------------ danger_uni's Profile: http://www.unicyclist.com/profile/21 View this thread: http://www.unicyclist.com/thread/27894 |
