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

Well this was supposed to be a conversion.. hah!

Started building my own 10oz oil tank. The aim is to be able to dig with the machine tilted at 45d in any direction and not suck air in the pump port.

After wondering of a way to be able to connect an external tank to the pump, it was a no go. It is some weird square bevelled intake port and the return ports are some odd size too.. no go there.

Then i began playing with dubro tanks and the faucet and came up with a design that will keep the intake oiled at all angles i can throw at it.

After a few weeks the jb weld shows no reaction to the oil (its watered down toy hydro oil anyway, bet you it can live inside styrene as well - my next experiment!) so i can use that to weld and seal the new tank... I was thinking .090 plates but went with .040 to maximize capacity. It's plenty strong.

More later after i go to mcmaster tomorrow. I only got a few pieces cut tonight before i ran out of .040 sheeting. Speaking of that, finished the .125 encasting of the body and couterweight and began filling in the screw holes. Liking the way its coming out. A bit like a mining excavator but not quite. Also began cutting out the channels for the chain drives. got my chain resizer in as well.


Also building my own bucket. I have to start keeping costs down, this is out of control.
