OK that's great thanks. Thinking about getting a local machine shop to weld me something up. Going to go and inquire this week about monies lol.

As Matt said, Defectors one of the robots built mainly out of HDPE (with an Ali frame).
Defector had 13 fights in total, and fought against a few spinners (Rango, 720, Galactus, Massacre, and LS4). Ill show you how it fared throughout the tournament.

It looks like its in a very bad state now, but the armour itself is in good shape. However the joins was what let it down, and it doesnt have replaceable armour. The welds had got busted by the end, and alot of the threads for the bolts aswell.
However if you make a robot with "Throw away armour" as it where, it would be a very good option as the frame should stay in good condition. You then just place new (and cheap) armour onto where the old got damaged from.
That said, id recommend a metal scoop, purely out of sharpness and its ability to stay sharp through a fight.
Should also state, if id needed to of fought again - Defector was still in a fully working condition.

You will find alot of robots which get that far in competition either need upgrades or general repairs, as doing that many fights in the competition can really take it out of them.
Defector was still fully mobile at the end of its last fight. All that happened was a bolt came out and it got stuck on it, once freed it worked perfectly still. Infact, by the end of its last fight it could still do Figure of 8's or whatever was required to prove mobility, yet its opponent had lost steering. All i needed to do to fight again would be to bolt the base back on and charge the batteries.
It got sent to Belgium to have some of the welds redone (which i can not do), and also primarily to be redesigned for next years competition, with a new flipper and new tires (for which i have undamaged orgionals).
So yeh - Fully working
In answer to can a brick be successful... from experience? No. Not without a wedge. I've run Ricochet without a wedge and despite having a 2mm clearance as soon as it hit something slanted it would ride up and be useless. With the wedge however, it made the top 18 this year. HDPE sides are 30mm thick and completely unbreakable. Lid is only 8mm and suffered greatly at the hand of LH3, but even with the total over the top 6 motors and 2kg of Hardox at each end it was 12.9kg at the champs. If the clearance were increased I could easily fit a 10mm lid in weight. What you really want is strong construction and HDPE to take the shock and dissipate some of it before it reaches the rest of the robot, lowering the overall impact. Hardened steels such as Hardox are no longer safe against some of the spinners, and are incredibly difficult to bend back.
Joining the convo a bit late in the day, but anyway, going Back to:
Errrr no, I think Endeavour can be shown as a testimony to that. Yes, if you use something like 2 screws to hold armour on then you are definitely going to run into problems. In Endeavour though, we used somewhere between 100-125 (possibly more) M4 screws to hold the whole thing together. I think its something like 26 screws alone to hold one motor down. At the champs last year (2013) we took 2 major hits on the side armour and all we got was a bit of a graze, no "panel ripping off" which is what you seem to be describing. Screws are definitely strong if used properly...
Would definitely agree with this, especially if the wood is used like spinner food! If you use really thick wood on top of HDPE or hardox etc, the spinner is unlikely to get through all the wood and even if it does you still have your "proper" armour to protect yourself anyway. Also the fact the wood splinters means that you are unlikely to get the "hit and flip" action that many verticals try to achieve.
Overall, yes bricks can definitely be successful, particularly in events like the Annihilator and the newly founded Gladiator Cup. It doesn't matter if you have the most destructive bot on the planet, if it doesn't run reliably, your never going to get anywhere
Yes 100+ screws were needed to make it effective. Or you could use 20 bolts with washers. Just my view after NST ripped Conker 1 apart and that was held together with around 16-20 screws per pannel running perpendicular to one another in pairs.
Defector was originally Hanibalito 4. (May have spelt that wrong) It's design was proven over years in other machines.
Defector is seriously impressive, as is Richochet (fought against you at Doncaster and got battered). I understand now about the need for replacement bodywork. My main thought was that to get through the rounds you simply need to keep getting back in the arena with a running machine half the time.

Does anyone have any thoughts on using blades to deflect spinners? Could this be a viable way to overcome them?
Not really sure what you mean by blades but the best way to deflect spinner IMO is to angle your body like Matt did with Hardwired, if you watch his fight with NST you'll see how effective the design was at deflecting NST's bar.
