Stainless and Ali armour

[mattsdragons]

How would it be rated against hardox? I have the chance to get it cheap and get it cut to size but wonder if its worth going for if I can get it thick enough and in weight

[maddox10]

Ali armor went out of fashion early 2000's.

Stainless is as good as mild steel, but a tad heavier and a lot more shiney.
If you can get it cheap, it's an option.

On the other hand, it's like comparing cotton to kevlar

[geeza]

Stainless will be ok generally it's about half to 3/4 as hard as hardox. Ally is useless as armour forget it.

[team_mute]

Mutes always had st/stl armor from year dot, weve added kevlar/Ti/Hardox to the bits that can get hit by axes but the sides are st/stl with HDPE on top, orginally it was st/stl with polycarb on top

[terry]

Do you have a tig welder then Matt ? I don't and did have a few bits of stainless so had to bolt it on !

[mattsdragons]

For the cost of hardox I could get the plates laser cut and welded so it's something to consider but don't know if it's better to look at HDPE for low costs or just go for it hardox but at quite a cost

It dose depend on the design of the robot. Mega Mouse uses Aluminium armour very well, with a Hardox or similar blade on the front.
Cherub is made of steel armour not Hardox between 10 -5mm thick, and is so far impenetrable.
Saint is rubber conveyor and 3mm arm400 Steel, wheels 12mm UHMWPE,
Gabriel is 6.2mm armour steel at the front, and 20mm HDPE top and bottom wheels the same!
none are weak as far as armour is concerned, also Beast has no armour to speak off and survives very well.
do you have a picture of your design?

[mattsdragons]

It's based off Omega/Yank that I have recently got hold of so will be chopped down and re-jigged a bit. Basically, flat haha

[daveimi]

The last time I talked to Trev he showed me huge gouges in the ally of Mega Mouse but didn't say much about it. I couldn't decide if he was fed up with it or not.

[craig_colliass]

Big wheels quite high off the ground SS or HDPE should be ok

[mightymouse]

Aluminium is ok if it is thick enough, but Meggamouse didn't like the constant hitting it was getting in Aus from Thor. But then you don't fight Thor 4 times a day and have to let him hit you.
Would like to change but 4mm Hardox will not be sturdy enough, and it would be cheaper to make a new bot.
Make the robot fast and agile and good driving will keep you out of trouble, look at Beast...

Trev

[shakesc]

Beast (and Beauty for that matter) are good examples of lightly armoured and well driven
I have to make mine like a tank which is more about my driving than anything

Trev - you said 4mm Hardox will not be sturdy enough. Is the Al much thicker? Interested in the comment.

[maddox10]

It's not only thickness that counts. Tough As Nails demonstrates that rather well, 12 years with the same3.2mm Hardox 450 armor/frame.

Flexibility and shape are other factors.

Also, dents and other battlescars ain't a problem, unless those are interfering with the rest of the function.

Better to have dented armor than rattled electronics.

[beast]

Beast and beauty's don't do armour

[shakesc]

Exactly, the closest I have got to a Beauty is the tip of the flipper arm Enough said!
