Hardox

The front ramming blade on Mighty Mouse is made from 8mm thick Weldox - it is as hard as hardox but is easier to weld.

Anyone who has felt the full force of the mouses blade will tell you it is tough.

It was finally bent this year by Mobot, I dont know the weight of the disc I rammed but it was petrol driven. I had the metal glowing red when trying to straighten it, and it took a sledgehammer to move it.

Trevor, weldox is not as hard as hardox. For example, the toughest Weldox availible at the moment is Weldox 1100 (which has a tensile strength of 1100N/mm2, hence the name). While Hardox 400 (which is the weakest hardox availible), has a tensile strength of 1000N/mm2.

If you then take a look at the hardness, youll see that Hardox 400 has a hardness of 400 HBW (hence the name), while Weldox 1100 doesnt even come close to this!

But thats only compared to Hardox 400, not Hardox 600 which would have been totally unfair.

so, does that mean that the new Dantomkia is quite tough? Being completely covered from the sides to the front?

Where could I get hold of some Hardox about 1700mm long and 1500mm wide by 3thk.

I need it in a hurry because the guy making the body is ready to cut out the bits but has run out of Domex 690 which I was going to use.

It needs to be clean and rust free or otherwise the supplier cant laser it out

Hardox gets supplied with a coating against oxydizing, so clean.... we ran in thesame problem in the beginning.
Solved that by cutting it with a blowtorch and using a lot of anglegrinder disks.

Now we can let it waterjetted.

And 3mm.. Im afraid thats not a current available format. Maybe Paul Cooper can supply the 3.2mm

Richard,

3.2mm is not a standard thickness made by Hardox, but the 400 and 450 Grades can be obtained at this thickness. If you contact SSAB in Droitwich (01905-794722), they will give you the name of your nearest supplier.

I bought 3 sheets of Hardox 450 at 4mm thick for the front of Bulldog it is a lot heavier than grade 2 Titanium, but not as difficult to work with,thankfully,

Hey Tony is that new profile pic the new bulldog on the left? Judging from the thickness of the Ram, it looks pretty damn powerful.

George that is one of the new rams, I have decided to have a choice of setups one 80 bore,
and the other two 50 bores, which are close coupled,the overall design is not for the Big Flip thats been done now,the design is a little different,
more a short vicious type of short flip,for this flipper speed is very important,so a short stroke
is the order of the day!

Ah, i see, so there is instead less of an emphasis on the Wheel Big Cheese style of getting in two big flips then dying out, rather to be like Chaos 2 and keep going the entire match on flipping, hence solving the usual flipper robots problem of starting strongly then dying out when you run out of gas. Sounds like a good idea to me!

yup:- nearly right

Did Gravity suffer from a low amount of flips?
