alternitive armour or different thickness

[mattsdragons]

hi everyone

im not very clued up on titanium, on in the fact that its strong, so forgive me if these questions seem simple

one of my bots has 1.2-1.5mm titanium armour on the sides yet im not sure if thats too thin for spinner events since i want to get this into full combat and im unsure if that would survive a hit from a spinner without having a massive hole in the side.

would this be able to take the hit? what thickness could take the hits without deforming too much (i know Little Hitter has 2.2mm titanium) or what alternitives could i go for that are more spinner resistant but of a similar weight?

2mm grade 5 titanium

i know it is, always has been and probably always will be. first day back at school and being tired are not helping either

Re: alternitive armour or different thickness

go get some from a titanium supplier. Search google for one.

As to thickness. The larger spinners will go through 1.5mm. I'd just stick with hardox and plastics. Far easier to work with and MUCH cheaper.

Wouldn't 3mm Hardox be a lot heavier than 3mm ti?

Re: alternitive armour or different thickness

yes it would but it would also be around a fifth of the cost if not more.

I need to save weight in other areas then

Re: alternitive armour or different thickness

Hannibalito III uses a mix of 10, 5 and 8mm HDPE, with 2 reinforcing armor belts of 20mm

We took damage, even had 2 penetrations from PresseR, the Hydraulic powered Crusher from the Pulveriser Team but never had a failure due armor inefficiency.

On the other hand, it's bend, welded and bolted, mounted on shockdampeners and tested to the bone.

Disadvantages. It's black, and the bends ain't that pretty.

What other ways could I save weight? I could do smaller batteries and a pipe line buffer tank but most of the design needs protecting quite heavily and I don't think I could do full 3mm Hardox

I could make a new flipper blade since it's 2nm steel box tubing and a 5mm steel plate on that, but if i was to make that out of titanium, would 3mm be enough if I can afford it?

Drilling Holes in all the box section

Re: alternitive armour or different thickness

how large is the 5mm plate? If it covers the whole flipper arm then cut it down so that it's just the tip that has the thicker material (for around an inch or so). Use plastic on the rest of the arm.

[mattsdragons]

Re: alternitive armour or different thickness

the plate covers the whole arm. the previous owner put it on since the arm bent after trying to self right on its side firing the flipper about 15 times

but drilling hols in the box tubing on the underside could work.

or... would it be worth grinding off all the box tubing and leave some at the base and tip of the arm for re-enforcment since the plate is 5mm steel?

Re: alternitive armour or different thickness

swap the 5mm steel for 5mm aluminium. Will weigh a third of the weight, won't cost the earth and should be strong enough along with the box section to stop bending as long as it's a good grade. There are a number of feathers that I've seen that just use a length of thick box section for the flipper arm. If you really want to go down the titanium route then 3mm will be thick enough however finding it will be a pain. I hunted ebay for weeks before finding some that was suitable for my purpose.
