Sure, now that I'm starting afresh it should be easier...and yes I'm hoping I'll be able to enter it in next year's Champs. This November I'm coming over to the Gloucester event, that will get me a bit familiar and hopefully meet some of you as well.
Regarding the armour, I really had no option as the material I had was not a full sheet. Thought about geting it welded, and in fact I might as well go on with it, the thickness might be a problem though but I'll ask around... btw its being mounted on 20mm hdpe, so even if a piece had to come off, it'll still have some protection.
The tracks should not be an issue now, the system is a simplified version of the previous one, now it will be totally encased making it impossible for the track to come off. Have a look at 6th post from top.
My main problem now is the lathe, have lots of parts that have to be machined and not having acces to one I'm seriously considering buying one...but that might take some time to happen!

Update:
So I just found out the local robot wars event will be held on the 10th November...perfect timing, the same day I booked for the Gloucester event! Tough luck! Will have to give the local event a miss...
Still, I have a robot to build and that will have to be built almost from scratch in 3 weeks! Looks like a mission impossible to me, but worth a try. My brother will take it to the fight if we manage to finish on time.
The tracks issue will hopefully be resolved with the latest (and final!) redesign. Machined again a set of wheels and rollers, and this time every thing will run on ball-bearings at both ends for better rigidity.
Yesterday had a new set of tracks custom ordered, I picked them up this morning...so far all is looking promising. This weekend will fit all parts together in the track holder and...fingers crossed!
Will post some photos later
Edit: Photos added
Drive is through the red wheel, will have to grind the motor shaft to 1/4"square. The middle roller is an eccentric tensioner. The other roller is the fwd idler.

Good progress over these couple of days, built the first track module (sorry no photos yet) and most of the previous problems look like they're solved. To test it I coupled it to an electric drill as I still need to modify and mount the Gimson motor. It turns ok with minimal friction and the track stays put, one less problem to worry about.
Now I have to copy and paste to build the other module, and then the rest of the build...

Should be ok, now...took some time to process the youtube upload! The video shows how the interals look like, but in reality the belt and rollers will be mounted internally as shown in the first two pics.

The build is going on overdrive at the moment! Only have till Tuesday to finish it off and I really doubt I'll make it:(
So I got most of the structure finished, drive as well (still untested), Hdpe under armour almost ready, now I'll trim the base plate to size and screw everthing together. Next will be securing the pneumatics and then installing tbe flipper arm....still a mountain of work to do!
Progress so far:

Looks pretty solid. Very nice work :)

Thanks Harry... it looks solid enough, but that will only be confirmed in combat!
More work in progress, today sorted out the pneumatics and their attachments. I'm happy by the result, everything fits in to the millimetre. Also continued the hdpe under armour, tough work with the plane to match and allign the pieces, but so far so good. Still doubting I manage to finish by Tuesday but I'll try!
Some pics of the progress so far and a comparison of the old vs new shell.

Feeling exhausted after a whole day at the workshop working on the machine...tomorrow is the last day I can work on it as on Wednesday will be off to the UK. Then its up to my brother to finish it off and make it work for Sunday's event!
We're almost there, track drive installed, tested individually but not as a whole unit, so so far its untested!
Flipper hinge and allignment in progress, but there's still loads to do! Most probably it will have to do without the titanium armour for now.
Some photos of the robot so far.
