reminds me of when you converted that linac to a dewalt for me, looking great

Re: Cobalt

That old motor is monstrous!

The old motor is huge for what it is, its only 300watt 12v but its a well made reliable 300watt can run it for hours with no problems

Re: Cobalt

Oh c***! Ok, let me go and completely redesign my robot... I will be back in 2 years! Bye...

Re: Cobalt

Did someone design a doughnut shaped robot with a 2mm Ti lid?

[Eventorizon]

Re: Cobalt

No, but all off the Ti is supported above HDPE to absorb shocks so that will make it really easy for him to cut through it... if he can get a grip that it. The 'skirt' on Conker II is 80mm wide! but I reckon Cobolt's bite depth is about 120mm

Re: Cobalt

Cobalt is really frightening, mate, good job! :shock:

Re: Cobalt

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

Re: Cobalt

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

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

Re: Cobalt

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!
