It was funny it just made the pic look like a broken windshield :confused: I ended up tracing the logo and scaling it down . I got a new cam :eek::eek: the logo is only .02 deep . I never had a pic that showed the detail like that :eek: got a lil tripod too , big help ;)

thanks Ed , Rod should be able to load trucks in june ( I hope )

Re: 990 cat loader
 

That really looks awesome. I love the Cat logo and grill!

Reg

Re: 990 cat loader
 

That's looking mighty fine, Steve! The new camera seems to be a good improvement over the old. At least we can see what you are building now! :) So how long before you start mass producing these 990 loaders?

Re: 990 cat loader
 

Wow. looks good Steve!
Guess has to talk to Santa already today, a new mill would be great.
Suggestion for moderators, with all those fantastic builds coming now built with CNC, maybee there should be a special headline for CNC tech/questions (under RC Tech section??)

Will follow this build closely!
Dan

Re: 990 cat loader
 

IDK Nate , right now it's my escape from making truck parts who knows maybe down the road someday , as for cat , not sure , depends on them :confused: right now I'm building the machines for me :o .

thanks Reg . Dan cnc not easy as it seems :eek: I can't imagine starting on cnc machining without some manual machining experience :eek:

Re: 990 cat loader
 

Dude that is too cool!!!

Re: 990 cat loader
 

**** Steve Every Build of Yours outdoes the next one

keeping an eye on this one


Alfy

Re: 990 cat loader
 

Very nice build Steve. The grill is waycool. Keep the photo's coming..

Re: 990 cat loader
 

Looking good steve-Looks like you have that c-n-c stuff down pat:D. Since I am older I always think back to the days when machinist were doing this kind of work with manual machines before c-n-c was even thought about. Don't get me wrong,the work you are doing is fantastic but I now have a greater appreciation for the older machinist. Looking forward to seeing this model working.

Re: 990 cat loader
 

Thank you Guys :)

I took a break this afternoon from cuttin wheel holes and finished up my spool carriers for my axles :o This way makes for ease of adjustment between the ring and pinion :D I would've like to have splined axle shafts , but this will do for now :(

Re: 990 cat loader
 

Nice craftsmanship on the carrier and the whole project as well. I can't wait to see it moving dirt or rock.

Re: 990 cat loader
 

Wow, love this groove for the big gear... :cool:
There's a good exemple of the difference between the new cnc users that can make "parts" and the real machinist in real control of the process...
Can't wait to see next steps :)

Re: 990 cat loader
 

Wow excellent craftmenship Steve. Love the new clearer and brighter pics. Keep the updates coming.

Re: 990 cat loader
 

thank you , guys ;)

I've been dabling here and there on this trying to keep at it to finish :o

I made a few things agian in betwwen TRYING to get ppls stuff done . As for the cnc , there are days I just want to yank it out of the shop :mad: I miss REAL hand wheels :eek:

deck plate

should've been able to let this go for 3hrs and do somethin else , but no , had to brake the program up into 5 programs :mad: the program was more then the mill memory storage on the mill and for some freak reason the DNC link would not werk this time :mad: oh well it's done 1400 holes :eek:

http://i830.photobucket.com/albums/z...r/DSCN0086.jpg

oil tank

somethings are best done manually saves on extra werk :( notice welded up hole :( ( thanks to Smokin Joe for Tig :) ) I still need more practice :o

Pump from Vanisle :) thanks Richard :) the robbe valves come as a bolt together unit for multiple valves . I'm going to make a 1 peice base when I get a free moment in th VMC

http://i830.photobucket.com/albums/z...r/DSCN0089.jpg

I got so disgusted with the shop 1 evening and roughed in the cab

http://i830.photobucket.com/albums/z...r/DSCN0090.jpg

I got a DRO for my lathe a couple months back . So I thought over easter I could get it put on :rolleyes: Well , I hope to finish it in the early morning tomorrow Ad be back at it learning how to think differently again :eek::rolleyes:

Re: 990 cat loader
 

Monumental build steve...5 stars on this thread....Keep up the good work

Alfy

Re: 990 cat loader
 

Steve, how did you ever become the machinist you are today? Was this something you did for a living, or just something you started playing around with, and self-taught yourself? Cause you're doing a fine job, and it's working for you.

Re: 990 cat loader
 

Nate , CNC machining is self taught and is a long rough road :eek: manuel machining some of both started at age of 13 on 12 x 48 hendy lathe keeping the equipment running . My dad is a ME , so I got some basics from him . Mostly , understand how something is made and how a machine tool functions with an open mind with a can do attitude .I still want a good manual mill bad :eek: . I should add I'm an operator , I cut my teeth on a "60's" 310 case dozer started full time At age of 13 on a IH TD7E :rolleyes: and still operate it to this day . We did our own repairs and attachment making . the 310 case is the only 1 to my knowledge with a 6 way blade

thanks Alfy

back to werk :o;)

Re: 990 cat loader
 

Don't you hate long load times and with these old controls. Did you repeat incrementally? Rather than separate event. But you did have 1400 holes I guess that would take up some memory that needed broken down.

Re: 990 cat loader
 

I broke it in segments (1 group of holes at a time ) the program was close to 200,000 megs or gigs IIRC . something that long I usually run it right off the floppy drive via DNC ( as the manual calls it ) it just been terminating part way through the program lately . could be the floppy drive . I guess I'm gona have to get that usb conversion :eek::rolleyes: the older mill I have to load it manually :eek: it use to have a tape reader that went bad . you know ,1 made from nonobtainium :rolleyes:

Re: 990 cat loader
 

Looking good Steve.

Research parametric programming (subroutines and loop calls) could probably do all them holes in a program a dozen lines of code long ;) assuming your control can do subs, loops, and variables.

Looks like should be a fun toy soon.

Re: 990 cat loader
 

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:

Re: 990 cat loader
 

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

Re: 990 cat loader
 

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...

greg

Re: 990 cat loader
 

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

Re: 990 cat loader
 

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.

http://www3.towerhobbies.com/cgi-bin...&I=LXLMV0&P=ML

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

Tim

Re: 990 cat loader
 

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.
Dan

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
