Looking good steve-Looks like you have that c-n-c stuff down pat. 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.

Thank you Guys

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

[mazdaparts]

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

[B-Train Hauler]

Wow, love this groove for the big gear...
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

[hauler_10-4]

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

[ihbuilder]

thank you , guys

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

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 I miss REAL hand wheels

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 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 oh well it's done 1400 holes



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





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



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



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

[MACK Daddy]

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

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.

[ihbuilder]

Nate , CNC machining is self taught and is a long rough road 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 . 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 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

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.

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 the older mill I have to load it manually it use to have a tape reader that went bad . you know ,1 made from nonobtainium

[pugs]

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.

I haven't got there yet it's not that old according to my age it's a cent 6 control prob. 1st gen there's so much to learn yet . 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

[steamer]

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

[Vanisle]

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.

[RCLogger]

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

[td9clyde]

awsome job on ur loader keep up the great work

[ihbuilder]

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 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 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 . 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

[9W Monighan]

Higher voltage means lower amperage.

[doodlebug]

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.
