Re: Build an Excavator from Scratch
Hi,
you've convinced me I wonder, why this forum isn't using such simple quick-response buttons as a "like". Its quickly made for you without spamming the thread and a response for the thread opener. thereby the opener hasn't the feeling to write soliloquies. A little sideeffect for me of writing in an english speaking forum is to improve my written english with non-trade-affected terminologies. I'm programmer by trade and the vocabulary of ibm books is restricted So I'll try to write more about my thougths why I do something so or not. ---------- Let's go back to the barrel tank. Looks good but it has some imperfections. I've forgotten a oil level indicator and a ventilation. I can add them outside, but a second point is more important. A kind master of hydraulics told me, that with my "big" pump and the small usual hoses I'll ran into problems with cavitation (pitting in the pump). The pump offers a g1/8 thread instead the usual m5 threads. to compare the hose sizes (top down): normal pressure hose id 2,5mm od 4mm normal pressureless hose id 4mm od 6 mm the new pressureless hose id 8mm od 10mm this reduces enormous the flow speed and avoid cavitation. Unfortunately, the hole for a g1/8 thread is bigger than the doublings in the tank. So i've decided to build another tank with all the needed holes and threads. This time a cubic form to get a feeling wich form is easier for me to build. I've not noticed significant differences, thus it will be simple a question of style in the future. The result. oil proofed and mounted. Ready to use.
