First generation in the new generation

[Tippin Spotted Cow]

I figured I'd put these up here for anyone who's interested in the technology, or just thinks its cool. I made a full 3d model in Solidworks in my free time at work. I made it kinda "freehand" though, in the sense that I didnt take any actual measurements, or even have anything to look at right in front of me. I just made a frame to rough size and built off that. Then I resized all the parts until they looked right (kinda). It's still a work in progress. I wanted to see if I could do it. In the future when I get a little time, I want to make dimensionally correct models of all the sheet metal on our trucks. When I start getting into body work, this'll help to know the exact shape I need to make to fit up flawlessly. I have even bigger plans with this technology than that though... . the sky is the limit here... .

Good work Tippin!!!

I have my old set of injectors still, I've been meaning to reverse engineer those in Solidworks too, so I can play with flow analysis and spray angles and stuff. If I ever get to that I'll get you guys some pictures, along with about a thousand other parts I've been meaning to draw up. I'd like to start testing fit of custom parts before I even spend the money... this would be amazing for getting exhaust systems to fit.

wow u are an engineer, i do the same kinda stuff, lol



awesome graphic work

Actually, I won the SkillsUSA state drafting competition, went to nationals and took 14th in the nation the year that I went.



At my last job I had to reverse engineer stuff all the time. We were a sheet metal stamping company so we'd get a lot of parts without drawings that people wanted us to make. I once had to do a throttle lever on a small engine... Not a surface on the thing was flat... it must've taken me about 3 days to get the thing right. I was basically the entire CAD department there so I had a lot nicer computer than I do now. I'm at a lot bigger company now, and the parts arent as complex, so I have a lot slower computer and thats kind've put a damper on drawing truck parts up. Most of them have too much going on that my computer just hoses up and I get to rattle off profanities and throw things. They're getting me a new computer soon though, because my boss made me the CAD administrator for the company, so then I should be able to start getting some more fun stuff. I actually used Solidworks to make my brackets for my stacks and to cut the elliptical hole in the bed so that the "Y" pipe sat flat on the bottom of the bed.



It works well because I'm a mechanical engineer and my dad is an electrical engineer, so he helps with all the computer and wiring stuff thats greek to me.



Hmm... I better stop... this post sounds more and more like a resume the more I type...

 

[JGrefenstette]

awesome pictures. so what was it that made such a smart guy like you get so into these old OilBurners??? way i see it, i have an excuse, ill more than likly be turnin wrenches on big rigs and heavy equipment the rest of my life, so its fun stuff for me. i would naturally asume that somebody in your line of work would make some good money and drive like a Benz or somthing.

 

[puff1]

Don't worry about it, tell us more!

 

[Tippin Spotted Cow]

Eh... I make good money and spend it on transmissions, apparently.



I've always liked working on things, and I'd be a little weary going under the hood of something that cost me upwards of $40,000. Besides, There ain't a vehicle on the road thats cooler than a first gen dodge diesel.



I work with a guy who came from Atlanta. He once said to me "If I saw your truck coming up in my rearview mirror on a backroad in the south, I think I'd need a new pair of pants. "

 

[JGrefenstette]

I couldnt agree with you more about 1st gens being the coolest ride on the road. yea when ive gone farther into the south with my truck, the guys down there seem to like it more. i guess old diesels are just too comon around here. but it sure turns a lot of heads, down in NC where im gonna be living in the fall.

That is a bad stereotype for engineers. Some of us are very hands on plus we know what it means to be frugal... note I didn't say cheap although there hae been occasions where moths have flown out of my wallet.

That's why I'm still driving the 91... saving for early retirement.

 

[JGrefenstette]

very true jleonard. my bad. i have a 26 yr old brother who is an Electical Engineer, very bright guy. he makes a very healthy pay check to say the least. and he would perfer to have a bmw or acura or somthing of the sort. and ive known a few others that are the same. but you make a good point.

 

[Tippin Spotted Cow]

CumminsChick, do you use any CAD programs for your job right now?

 

[CumminsChick]

CumminsChick, do you use any CAD programs for your job right now?

i'm familiar with CAD and a Solid Edge program but currently i work construction so the prints are already done i just put into reality at this point. with my ME degree i hope to get soon, i will do a lot more CAD work. but i have used CAD alot around the house, i am redoing a 200 year old farm house and basically gutting it and making it myway so i've used CAD to estimate supplies and what kinda spacing i got to do with it what i want... .



ima engineer and i'll drive my Burb and First Gen till i can't anymore and then i'll buy another smokey muscle truck and do it again

yea i here what yall are sayin i understand engineers much better now

You can tell we're mechanical engineers... Theres a world of difference between mechanical and electrical engineers. The first gen cummins is basically a mechanical engineers wet dream. There are 2 wires you need to have our motors run:



1. The one that keeps the fuel shutdown solenoid open

2. The one that powers the lift pump



Other than that our motors are completely mechanical, meaning all adjustments are mechanical. You know how to use your hands, and understand a little bit of physics and you can make that motor do whatever you want.



An electrical engineer, however, will tell you all about the reliability and more stable running of a motor that has almost everything on it computer controlled... which isn't neccessarily false, but the reply to that would be that the more you have going on on those newer motors, the more that can go wrong... a horse a piece.



CumminsChick, thats awesome that youre into the architectual/civil engineering side, too. I took a few arch. drafting classes on AutoCAD and I loved it. I would have loved to have gotten into it, but I think I was better at mechanical.

wonderfully put. i couldnt agree more

And 50% incorrect! Our lift pumps are mechanical.

And the wire to the IP can be done away with if you remove the plunger and use the manual shutoff.

 

[JGrefenstette]

yes... . even better. well tippin how do you describe it now??? :-laf

 

[Tippin Spotted Cow]

Hmm... with all the time I spend under there, you would think I'd have noticed that there are no wires coming out of the pump, but now that you mention it...



I blame it on alcohol... I can't remember the last time I worked on my truck without the essential tool... beer.

Autocad

I love it! Last night i doodled out a bumper / grill guard in Autocad. I am thinking 2" square tube in the center with the corner forward. I like the one on the bottom, but am having issues with the winch access cover. .



I have my BS in EE, but have done some mech design / 3D modeling in the past. I had to make do with using solids in Autocad. I used Chief Architect to design my house before I built it. Typical engineer though. Design for 4 years before building. There are those that would have it built long before I even started.

Now I am an accountant. (who enjoys tinkering his truck into "what it should have been")



This thread just goes to show that you never know who might be behind you in that smoky old truck.
