990 cat loader

What ring and pinion gears are you using?

Digital multi-meters work good for current draw readings. You just put them into the circuit, in series, with whatever you want to get a measurement on. Or you get a clamp on meter that can do DC amps.

I also bought a Watt's Up meter. It also goes in series with your load. Pretty cool little device, but I haven't used it much. Kind of a neat little toy to play with. Just to see what kind of load your motors are drawing. It also monitors battery voltage too at the same time.

Interesting! Look's like "big bang for the buck!" thank's for sharing that.
Cheer's, Neil.

Cant wait to see it moving dirt! The front of the Cab looks spot on!

Always nice to see those big loaders. This one is coming together very nice, looking forward to the rest of it.

well I'm going to sping for the big esc for this and run it on 24v I got the room for the batteries yet meanwhile , I got some robbe valves from Richard with the pumps . Of course I didn't like the why they go together + It seems you need end pieces also for the ein /aus ( supply and return ) Well , I made a new base ( now lets see how long it sits till I get taps ) arhh , must have a bur on the vice now I gotta plane the 1 side again we'll see how these hold up :confussed: I may find some ci bar to remake the alumminum parts . I'm not to keen on steel on aluminum

Robbe valve





new base block







well thats it for now , vice comes off , set up for next parts run

[mazdaparts]

That block looks great.

Nice looking work. You got cnc, get a couple threadmills

[RCP57]

Hey didn't I just assemble that yesterday? Looks good!

can you get them for 2mm ? I know you can for 5mm

" Hey didn't I just assemble that yesterday? Looks good! "

LOL

[pugs]

Oh yeah, that small might be tough to find. I pretty much only use them for over 1/2", all pipe threads and specials. Makes the best sealing pipe threads

got the oil tank on finally and the left side compartment . I should've used the lil tri-pod for the pics









thanks for looking

[Espeefan]

I get goosebumps looking at this thing. Love the rear tire squat! What a beast!

[kerst]

Looks great!

The loader is looking great Steve, if your not careful it is going to weigh as mush as my dozer.

[caterpillar]

woaw! truly amazed by this professional built. just wonder how you get to the drawings to steer the CNC machines. are this self made in cad? looks phenomenal!

thanks Joe , heh heh I think it's getting close for some reason , I can't make anything light

Thanks Cat , 1st it started as a pic from the sales brochure imported into auto-cad , scaled to 1:14 scale , many hrs. of tracing and tuning up the tracing . 2nd ,many hrs. of design of all the components as an assembly .
3rd , break the assembly into parts , duplicate where needed , place parts of same thickness on that certain thickness plate in such a way as to min. waste . keep in mind I'm doing all my designs in 2D . 4th import part plate file to cam , hrs. of programing ( for me any way ) , simulate to make sure everything is what you want (IMPORTANT) double check , triple check , maybe quad check . 5th, load file in machine and set up (IMPORTANT) double check , triple check , maybe quad check 6th , push green button and watch crunching action in blink of eye only if you DID NOT , double check , triple check , maybe quad check . As you can see this CNC thing has and still is a rough road for me yet I still like hand cranks , but , with what I can do on the VMC now , this CNC thing is catching on .

I think ill stick to styrene!! It amazes me still how you guys can take a picture and crank out a part that looks perfect like that!!! WOW!!! This loader is looking bad a$$!!

A few pics of to days carnage I made a bunch of brass shavings and a few parts (cylinders ) not quite done ran outa day + the groving bar I made with major inferior material didn't werk so I gotta order 1 Need to cut the ID seal grooves in the glands . I also got the front drive shaft hooked up last evening . I also remade the engine hood . the 1st was made from scrap panel from a delivery van which didn't bend to well without breaking ( not 6061 ) so I picked up a peice of .125" 6061 sheet and re ran it . No pics of the new 1 , forgot that pic .







thanks fer looking
