Cobalt

[Kenny]

Update : Started to make the all titanium hydraulic cylinder for the new cobalt ( In pictures next to old cylinder )

Wow, that is a significant change in diameter, if you use that pump with that new motor what pressure should that achieve in comparison to the old ram, more that double by the look of it! That is going to scary powerful, and the other one was good to start with!

Oh and the wonders of CAD

nice job, all a bit scarry

The pump is now developing 3000psi, with the old 32mm bore ram it was making 1600kg, with the new 2 bore ram its making 4200kg

So the force has gone up by more than a fact or 2.5... we are all in trouble! Will the chassis be able to take the forces though? Well again, CAD to the rescue!

Looking really good mate, that's the best quality hydraulic ram I've seen built! What wall thickness did you go for on the ram?

4 tons will be a good test for the chassis

Thanks mate, 6mm wall , may put the ram in this chassis and film it for a laugh to watch the front snap off

[calumco]

looks mint! whats the distance from the front of the bottom jaw to the back of it where it meets the claws pivot point roughly?

[sam_smith]

Good choice... so you could easily run that ram to 4000 psi if you wanted to in the future.

Lol, I remember writing off a couple of the early Tiberius chassis's... wish i'd thought to video them.

Don't want to flame anything, but assuming 3000psi, 2 I/D, 6mm wall, and depending on the grade of Ti used, your ram could be borderline from a pressure point of view. Looking at the picture posted, I'd guess that the tapped holes are reducing the 6mm wall too?

Not poo-poo-ing anything, just want to say be careful - especially if its Ti Gr2.

Nice looking bit of kit though.
