40cm is a bit on the narrow side Jack, the 2 magmotors by them selves are already that wide. try somewhere between 65 and 80cm, thats a lot closer.

Co2 is measures in kg, not liters. but I get the point.

If I were you, but that is up to you of course, I would switch from 2 rams of 110mm, to 1 ram of 110mm. that is still 5 tonnes of force (more than Gravity 3) and with the weight you save you could fit a 2kg bottle in there.

ok thanks leo

i will switch from 0.4 to 0.75

i will have 1 ram now and fit a 2kg bottle instead

blimey, 5 TONNES of force! guess ill get a few ootas then,

jack

Jack, to be honest, 5000kg of force is WAY too much. Vapours tend to aim somewhere around the 1000kg-1500kg mark, as it gives suitible power without blowing ram clean off.

I think a ram produced 3500kg of force.

To tone it down, you do the sum

maximum force divided by the force you want = the ratio to give your flipper.

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).

**majinb** · 14th August 2008, 12:02

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...

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.
