Default Re: My Mruder (bruder cat320 something look alike)

I meant dirty as in digging video

The reach is ~2.5ft up, down, across. 1400 comes to 4.5ft. that's insane. i cannot counterbalance that long of a boom on this thing anyway. after i beef up the top side to a scale body, i will be maxing the undercarriage to its "looks small" limit. and i even stretched that 1" over stock as is. i considered making a totally custom bottom out of robotics tracks and what not, but that would push into another realm of expensive and labor intensive

I am getting a lot of foaming in the tank and it sometimes overflows when the main boom is lowered all the way down, then when it's raised, it runs low on fluid as you can hear/see. That leaking piston isn't helping any either im sure.



I need a bigger fluid tank. Any way i can jerry rig one on top of the stock without screwing up the venting system? All bigger capacity pump/tank combos were special order so i didn't go for them.

Epoxy i know.. i have never done that before honestly. Not on such large scale anyway. I have 0 access to CNC, or cad skills to even produce a model for 3rd party machining. The 2 companies in the area that do custom cnc produced a look of utter disbelief so this was a no go. So it's hand tools only and unorthodox approches to everything on this build it seems
