Re: Wheeled excavator Liebherr A934
 

Very, very nice work! You are a true craftsman. Not only with your machining and metalworking skills, but also with your styrene, brass, and soldering skills. The counterweight is very impressive. Was it 3D printed, or CNC machined? I like the casting line / rib detail on it.

Re: Wheeled excavator Liebherr A934
 

Impressive!! To say the least.:eek: Wish it were mine :D:D

Re: Wheeled excavator Liebherr A934

Re: Wheeled excavator Liebherr A934
 

That is a great project! I like the use of the slip ring. Very creative way to put the model together. I'm working on a similar model of a CAT M322d.

I had a few questions:

1. What do you use to lower the stabilizer legs (linear actuator, etc)?
2. Where did you get your hydraulic cylinders (or are they custom made)?
3. Did you make this from plans or CAD drawings?
5. Looks like you used a brushless motor for your pump. What is the Kv and how many volts are you running? Is the mount custom made?
6. what size brass tubing are you useing, and how did you get the barbs on the ends?

Thanks! Paul

Re: Wheeled excavator Liebherr A934
 

Hi ;)

1. linear actuator with Polou geared motor - custom made by me
2. custom made by me
3. yes, I draw myself in the Q-cad, and I cut on handmade cnc milling machine
5. this is Roxxy BL Outrunner 2824-26, 1380 kV, LiPo 2S (if you using 3S then kV must be 1100 - Robbe Roxxy BL Outrunner 2824-34), motor plate is custom made by me
6. tubing brass size is 12mm outer diameter and 10mm inner diameter

Did you start with the green seals, then change to the blue? Or are you using both kinds together?

Re: Wheeled excavator Liebherr A934
 

Yes, I changed to the blue because green leaked ;)

Re: Wheeled excavator Liebherr A934
 

...and the green was Typ U2?

Re: Wheeled excavator Liebherr A934
 

No, this is simmerring NAK 5x10x2 mm, this blue is a sealant TTU 5x10x5mm. Simmering is good for rotation, while TTU sealant for planar motion ;)

This is just incredible styrene work! It looks like a injection molded styrene body. How do you get things cut out and glued together so perfectly and seamlessly? Or is this 3D printed?
