I haven't got there yet :o it's not that old according to my age :p it's a cent 6 control prob. 1st gen there's so much to learn yet . :eek: I hope so (soon ) I've been trying to get some construction equip going for awhile now . life just gets in the way more times then not :confused:

Loaders looking real good Steve. Just think if you had to drill all those holes by hand it would have taken three weeks.

Wow, that's pretty impressive. When I see how much work goes into a project, I feel less bad about not making time on my own stuff. I like those holes but I would hate to do them manually with a DRO.

Re: 990 cat loader
 

Keep up the grreat work Steve, it is going to be able to move some serious material. Alot of pump in there...

awsome job on ur loader keep up the great work

Re: 990 cat loader
 

thanks guys ;) I just checked the specs on my motor 2HP at 24v @94.5 in/lbs of torque with out the planetary gear box which brings it to 550 in/lbs of torque . It draws 2.6 amp no load , 68 amp nominal , and 190 amp stall . But I'm only running 12v on it . Soo , now how to figure the esc :confused: just get the 1 rated for the motor specs @24v to be safe ? Or could I get away with a lower rating / 12v is all I'll ever need in power on this thing :eek: It can fill the bucket going straight into a pile of pea coal like nothing on 12v. Pea coal is about the size of scale R8 and up rock which is more then expected for this machine to handle . I was told I'd be fine with a 1/10 cc sidewinder sv2 but I just want to make sure . I'm still green when it comes too electric motors :o . I might do my cab in brass as I got some of that laying around ;) .
I'm gettin antsy , I'll actually have a piece of equipment running via RC :D

Higher voltage means lower amperage.

Re: 990 cat loader
 

Hey Steve, do you have any way to measure motor amp's? Maybe an inline fuse on the drive motor lead's? Car stereo one's should be big enough (battery cable version)
Can't wait to see video!

Cheer's, Neil.

Re: 990 cat loader
 

What ring and pinion gears are you using?

Re: 990 cat loader
 

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.

Re: 990 cat loader
 

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

Re: 990 cat loader
 

Looking great Steve!!:cool:I will be watching this project!!!:D

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

Re: 990 cat loader
 

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

Re: 990 cat loader
 

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 :eek: meanwhile , I got some robbe valves from Richard with the pumps . Of course I didn't like the why they go together :rolleyes: + 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 :eek: ) 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 :confused:

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

Re: 990 cat loader
 

That block looks great.

Re: 990 cat loader
 

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

Re: 990 cat loader
 

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

Reg

Re: 990 cat loader
 

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

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

LOL :p

Re: 990 cat loader
 

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 :D
