School me on hydraulic components

[Lil Giants]

I already have it with my JD850 & won't be replacing it... perhaps forever, just rebuild what needs to be.. when it needs it.

However, I was just talking with Frank of Fumotec (the designer/fabricator of the Vario hoe), this is what he told me in an email a few days ago..

"Bauma Fair / Show in Munich it´s the world's biggest show for construction machines and equipment. There on the Komatsu both should my latest upgraded wheelloader the WA500-7 and the brandnew excavator PC 490-10 be ready. This whill be a hard work to get both models finshed."

The show is probably later April . All the models I have seen of Frank's creation have been solid, durable, well engineered... maybe less so on the perfect scale detail, but the core is there to build on, and the modeler who cares about scale perfection (not me ) can add their own details to dress it up. The pics of the tracks that Kalle posted in my thread are designed specifically for this excavator... which is why they may not be an exact transfer to the Vario model.

That'll give you plenty of time to read the forum threads before that 490-10 makes it's day view.

You're welcome... this is what forums are for, information trading to grow the hobby bigger and better with each new year.

Wow, that's exciting news. I'd be very interested to hear more about those models. I don't want to sound too naive but your JD 850 is made by Stahl right? B/c vario makes one too? Just a bit confused.. Can't tell differences between manufacturers yet? You had suggested Vario for an option before and just wondered if the 850 is made by both company's why you picked one over the other... I'm mesmerized by it in your vids. Super badass.
So I got a response from the German dealer in regards to the Leimbach conversion parts for a bruder. Kit consists of 4 cylinders, all parts are leimbach except servos are Futabas. price is 1200.00 us plus shipping. System runs at 145 psi.

Bruder excavator.

This set contains:
12mm cylinder
pump
control valve
Servos for control valves
T-connectors
hoses
securing sleeves
hydraulic oil

This set is designed for Bruder excavators.

This set is not available from stock and will be ordered for you.

Do you think this is a good setup for a machine that may possibly be built from 18 ga steel.? What mean is I'm thinking of replicating the 320 on sheet metal and possibly adding an inch or 2 to the reach. Will this hydraulic set up have an issue with the weight? I have no frame of reference having never operated a similar unit with that pressure. I wouldn't want to build the model to find out its underpowered or suffers under load. I want to be able to dig solid ground. Ya know?
