[FW] Wedge Spinner in time for Robo Challenge champs!

[ady]

Mate sounding Pretty good but you ain't got much time so I'd start building :-)

Where you getting your titanium fam?

Drumroll's side armour weighed about 670g a piece last year if I remember rightly, and that was a 3mm steel angle frame supporting two layers of 8mm HDPE, so yours shouldn't weigh too much and leave you enough for HDPE on the back too.

@ady, i have started!! :P CAD was a big chunk of the work to be honest. Sorting out wheels and various other little bits while I wait for parts to arrive now.

@Harry, the 5mm is being suppled by Control Waterjet along with the 15mm 7075, and the 2.5mm Ti by LaserExp... Control had a 5mm sheet already, LaserExp are ordering it in, with a lead time of around 5 days.... which isn't ideal but I've emailed so many places and not gotten anything back.

Hardox is coming from KCut, who seem to be really freaking cheap to me?? £10 per disk! Maybe I just assumed Hardox was costly stuff but it isn't?

Ok, so as of 5mins ago, after filling in the champs application form.... this robot is now named... FISSURE...... that's scary enough right??? Me and Dave are now called Team Meltdown, named after the first ESC we built which went up in a glorious pillar of flame.

I hope my robot building skills are as fast as my crappy name generation skills!

[Rapidrory]

I've heard worse names; I panicked when signing up my first feather and called it Richie
Definitely approve of the team name, all proper ESC projects involve fire at some point! :P

Some parts arrived yesterday, XT90's for building my double removable link, some 10.9 steel m20 bolts and nuts, as backup shafts (main shaft is silver steel kindly being machined by Harry), the linear bearing mount wheel hubs from ebay, and of course the hardox disc, which scares the shit out of me even when its not spinning!

Also, My titanium providers have failed me! When they said "we have found some 2.5mm grade 5" they meant that they found a giant sheet, which I can pay £800 to buy all of.... which is a no go for me!

Instead, I'm now building the base plate from alu 6082T6, the wedge from steel and the sides/back from thick HDPE.
The one thing preventing me from placing the order is choice of steel. The waterjet cutters only have 6mm hardox thinnest, which is too heavy for me. I'm after some 4mm steel for the wedge. Can anybody suggest a type of steel that would be an appropriate replacement for hardox?

The disks look excellent and capable of inflicting plenty of damage. Its disappointing about the titanium; I have the same problem getting cut ot size Ti and have to import it all from Titanium Joe in the US.

Looking great!

With regards to Titanium, try Ti-Tec UK in Birmingham. If they have it in stock it can be on your doorstep in a few days.

Are you sure you want to call in Fissure?

Google it.

[Eventorizon]

Yeah... some better name alternatives: Abyss, Chasm, Crevasse...

[Giles]

Hahaha oh dear, not that kind of fissure!! Why does the internet have to ruin all harmless words!

[RogueTwoRobots]

If you call it Fissure, it could become the butt of all jokes
