if you have cut all the pieces the same use the first panel as a jig for the rest by welding smal pieces of scrap up each side on the corners this will save you a lot of time once assembled in the jig weld all the corners on the vertical plane first this will stop it twisting then weld each side normally the only thing is you need to do vertical up welds but even tacking the verticals first will keep it mostly straight

Does anyone in Queensland know where we can find some second hand carpet? If yes flame throwers will be banned.

Carpet in ... arena? How does that work?
You shouldn't find it too hard to come by, if you don't mind flood-soiled. _________________ ( •_•)

Have a look in the industrial bins outside a carpet shop. They generally take away the old carpet. _________________ So even the rain that falls isn't actually going to fill our dams and our river systems
Building this weekend? My brother has drop saw but hasn't had time to drop it round yet.
How wide is carpet do you want to join it Carpet would also be very interesting for some robots. Lino? _________________ Steven Martin

Building will be done this weekend but we don't need the saw. All the steel has been cut and the jig has been made so it will be just welding this weekend after I pick up some more welding wire.
The idea of the carpet is that we can have a seamless floor so idealy we need a piece 5m square. The difficult part is finding carpet suitible for wedges. Also 2nd hand carpet is right for our budget (ie free). _________________ Get Some!!!

What do you think will happen if a spinner gets tipped up so that it's blade contacts the carpet? _________________ So even the rain that falls isn't actually going to fill our dams and our river systems

We are thinking of an MDF floor for next year, with luck it'll be easy to repair. _________________ Mechanical engineers build weapons, civil engineers build targets

Yes indeed carpet=fail in my opinion as far as arena floor goes.
A nice sturdy thin steel or mdf or general wooden floor should be fine and acceptable for most robot designs
I can see my disc getting entangled in carpet and being a fabric i dont see using it as flooring in an arena ending well for a fair few people. _________________ Andrew Welch, Team Unconventional Robotics

We did demos on carpet at the model engineer’s event at Monash years ago.
The bots moved ok, even Cobra with zero ground clearance but that was fastened down properly and there were no spinners to tear it up.
Was going to use Pyrobot in fact worked on him on the weekend so it looks like it will have to be Badger. _________________ Satisfaction is proportional to effort and results.

running on it wouldnt be so much trouble as the damage i think. maybe lino would be better or easier to get?

I think you forgot the free bit.
The idea is to have a 12mm wooden floor and then for the first day nail down some carpet as a test to see how it goes. If it doesn't work then my brother and I will spend all night pulling it up and removing it for the next day. Our origional plans was to use astro turf or another simalar plastic non-looped carpet, but that stuff costs money.
