No Paul, the ram produces 5 tonnes (110mm). What he gets on the tip of the flipper is what the ratio, as you point out, will be (as in where along the flipperarm you place the ram).

I have to say though 5 tons of force at the ram is something else then 5 tons of force at the tip of the flipper Paul...

damn, Leo beat me to it...

Paul! Friend! I am so going to make your day.

Guess what, it will be a tight for for batteries and you will need to play with the hinges a little, but with a 1.2kg bottle it will fit.

Hooray! Thanks Leo! About the batteries, would 120x 3000mAh NiCad cells producing 12amps suffice 2 MagMotors?

Paul, yes they would. Barely, but yes.

In response to this battery thing, see my new topic, i think this could help all of us.

Something which might be worth pointing out on Knyfe

Height - 220mm (22cm)
motors - Lem 200s which have a diameter of 205.3mm (taken from http://www.lemcoltd.com/downloads_pdf/lmc_200_motor_assembly.pdfhttp://www.lemcoltd.com/downloads_pd...r_assembly.pdf so Lem 200s should really be called Lem 205s)
Top armour - 6mm Hardox
Bottom armour - 4mm titanium
Which gives a total height of 215.3mm assuming there is no gap between motor and armour panel
Ground clearance - 8mm, so in my mind thats the gap between the body and the ground, so doubling that to give 16mm, gives a total height of 231.3mm, 11.3mm taller than what says in the stats (again assuming that the 4cm rubber is just on the sides).

Also:
LOCOMOTION: 6 Vulkanised Wheels.
So the entire wheel including hub is vulkanised rubber?

Dave, about the wheels youre being pedantic

And its now 25cm in height

[kodster]

No, hes being serious. How do you expect to move with wheels made completely out of rubber? :P You have to state otherwise, or people will take what you say in the stats. :P

[davids]

What, I sometimes do research into stuff

But you might want to write in your stats that the wheel hubs are steel or something, and another thing worth mentioning is how the wheels are driven (as I kinda assumed they were chain driven with the motors between the rear 2 sets of wheels

[paulc]

FFS! First I have to stat batteries, but thanks to Leo thats OK - but do we NOW have to be SO petty that we need to state if something is belt or chain driven. You were stating in another thread that all the fun is being taken away...be careful what you say.

It has been done before with solid rubber wheels, its just not really the best use of weight

[leorcc]

Paul, just say they are aluminium with a vulkanized rubber thread, thats fine.

As for belt or chain driven, both is just as good (or bad). I prefer planetary gears or spurgear drives anyway.

Are titanium hubs a tad too heavy, Leo?

[leorcc]

How could I Improve pt 2

7075 Aluminium hubs are twice the strength of stainless steel already. You could use Ti but what would be the point? Its just more weight to hold a piece of rubber in place.

All right, thanks for the advice.
