777 HAUL TRUCK (1/12 size)
 

Here are a few more recent pics of the "1/12ish" size 777 haul truck I have been working on for a while now... later I will start at the begining and work forward through the build.....

I tend to build simple stuff not true to scale, lacking in detail and usually over build things but hey as long as it works!!! LOL!!!

I also have a link to a vid for this truck that may be helpful...

Re: 777 HAUL TRUCK (1/12 size)
 

That's an awesome custom build you've got there. Great job.

Re: 777 HAUL TRUCK (1/12 size)
 

Thanks!! Now if I could only get it finished...LOL...

Re: 777 HAUL TRUCK (1/12 size)
 

OK so here is how it started.....the first thing I like to do once I have created a CAD/DXF file for a project is to (water jet) cut a simple plywood profile to see what it will look like more or less..LOL...sorry I'm a bit old school and looking at a drawing isn't the same as having a full size part to work with, besides having a simple plywood models gives me something "real" to look at and get ideas from and a 2D drawing doesn't always work the same in a 3D world...LOL

After I have the plywood model cut out I start designing and cutting the metal parts, making changes as the build progresses...most times there is more changes and less progress...LOL...learning all the time !!!

( here is a vid of my first build... A 1/12ish D11 www.youtube.com/watch?v=AV596tHo0_o )

Simple rear suspension cylinders ( about 3/4" stroke) machined from pipe then welded and finished. Time will tell how good and for how long this will work....somethings ya just go to try....LOL
( there is nothing to stop them from pulling apart... I have recently built stops into the rear swing arms to limit the down travel...not sure how many time I lifted it up and pulled it all apart...funny how springs and any small parts like to bounce around and always end up rolling underneath something )

Re: 777 HAUL TRUCK (1/12 size)
 

It looks really good! I can't wait for you to get this done so that you can start on the next project on your list!

Re: 777 HAUL TRUCK (1/12 size)
 

That's a good laugh....I'm having a hard time building this truck!!! Building the PC1250 face shovel will be nearly impossible for my little brain...LOL

Re: 777 HAUL TRUCK (1/12 size)
 

OK this is for you Reg....it's started....Happy now?? LOL!!!

Re: 777 HAUL TRUCK (1/12 size)
 

A few more pics of the truck , D11 and work bench or at least I like to call it a work bench even though there doesn't seem to be much work done on it...LOL

Re: 777 HAUL TRUCK (1/12 size)
 

Progress on the frame and box.....keep in mind many things changed as I continued to build, so you may see things now in the pics that have now been changed and or removed...because I didn't like something or in most cases it just didn't work....

Re: 777 HAUL TRUCK (1/12 size)
 

Building the rear axle housing and bearing holder mods

Re: 777 HAUL TRUCK (1/12 size)
 

Changes made to the frame and swing arms in order to use a linear actuator as a hoist cylinder ( Firgelli linear actuator 12volt , 35 lbs , 9" stroke) This is one thing on this model that is not like the real deal....only a way of making it work, which is something I can live with as long as it works!!??

(The main frame is cut from 1/2" plate and the box frame is 1/4")

Re: 777 HAUL TRUCK (1/12 size)
 

Front strut build pics ( about 1" travel ).....almost like the real deal...LOL...they will eventually get covered in so you don't see the springs and help keep dirt out.....
(cut from 3/8" plate and 1"-1018 bar stock )

Re: 777 HAUL TRUCK (1/12 size)
 

More strut pics.....

Re: 777 HAUL TRUCK (1/12 size)
 

Pretty impressive!

Re: 777 HAUL TRUCK (1/12 size)
 

WHOOOO-HOOOOO!!!! You are showing signs of addiction my friend! I can't wait to see all this stuff moving dirt. That shovel will need some good quality hydraulics but will dig like crazy!

Re: 777 HAUL TRUCK (1/12 size)
 

Wow, That's coming along nicely. That water jet really makes it look easy.

Re: 777 HAUL TRUCK (1/12 size)
 

DADSGARAGE-That is some nice work. I built the 777 but it was at 1:30 scale and was really difficult to build because of the size. My completed model would fit inside your box with room to spare. Are these the tires that will stay on your truck? Good job!!

Re: 777 HAUL TRUCK (1/12 size)
 

HAHA...signs of addiction to this hobby really?? Not me I can handle my hobby I can stop anytime I want...( OK so I'm in denial )....

If you are interested check out this vid, it's a bit boring but it is one of the few vids of a PC1250 set up as a face/front shovel.

Re: 777 HAUL TRUCK (1/12 size)
 

Thanks.....and yes the tires you see are going to stay on the truck, they are a bit small but they are close to being the right size, the rims will all need to have some mods done to them I have made some changes to the rear rims and have done nothing with fronts yet

Re: 777 HAUL TRUCK (1/12 size)
 

Thanks for the comments guys....I will post more pics once I set up something on Photobucket or image shack...I don't want to waste any more space on here with pics...I just got on a roll posting and didn't realized how many pics I posted.. (OOPS SORRY!!)

Which of the two free photo sites is better?? Or are they both just as good or just as bad??

Re: 777 HAUL TRUCK (1/12 size)
 

:lol::lol::lol::cop::cop::cop: Glad those weren't my tool's that got run over:p:p:p

I like the plywood mock up idea!
Cheer's, Neil.

Re: 777 HAUL TRUCK (1/12 size)
 

Hey i like that haul truck, I use a waterjet at my work and I use the plywood technique on some of my projects. I have built a couple of excavators with it.
Nice job :cool:

Re: 777 HAUL TRUCK (1/12 size)
 

Glad to see someone else that has some experience with waterjet cutting, they are very useful and versatile machines...funny why more guys on here don't get parts cut on a waterjet or lazer...or maybe half the fun and challenge is in cutting the parts by hand at home. Or is it hard to find a shop that wants to do small jobs.........

Re: 777 HAUL TRUCK (1/12 size)
 

Well a great intro to your projects thus far Kordell. :cool:

I've been using photobucket for yrs & the last 2yrs been a subscriber for less than $20/yr. It usually works flawless for me, but it's the only one I've ever used. I saw your link to the comparison sites, pretty much any one of them will suffice. ;)

I see waterjet getting to be more common place all the time b/c more modellers are building the model core with steel instead of aluminum for greater weight, easier to weld together, less wear, less fatigue, ect.

Re: 777 HAUL TRUCK (1/12 size)
 

Wow, this is a really great project! I'm subscribing. Looking forward to the updates as they come.

Re: 777 HAUL TRUCK (1/12 size)
 

Thanks Joe

I will most likely go with photobucket , seems to be the most used on here....

This is a good site to learn about waterjet cutting

Here is something else that might also interest builders...small plasma tables

Re: 777 HAUL TRUCK (1/12 size)
 

Thanks...glad you like it!! Slowly getting it done....as soon as I decide on a place to store pics I will continue to show more of the build and bring it up to date....

Re: 777 HAUL TRUCK (1/12 size)
 

The operator did stop....for a second or so...LOL...and then he drove them over (that was the most exciting part in the video...LOL )

The plywood profiles are very handy...and easy to cut on the table...it also helps keep my kids from asking me when they can see something other than a drawing...LOL...

Re: 777 HAUL TRUCK (1/12 size)
 

Ok I got set up on photobucket...try to add some pics

Cut some test sprockets.....didn't buy the right ones so I made some to test the drive and speed (.250 Pitch )

Re: 777 HAUL TRUCK (1/12 size)
 

First try using this type of steering control ( this one did not work needed some changes )

Used a Hitec 785 winch servo ( 3.5 turns) and a 12T sprocket ( servo city)

Re: 777 HAUL TRUCK (1/12 size)
 

Needed to get this thing on all fours...or should I say six....
Cut the bearing hubs off the cheap rims that came with the tires , then made simple front hubs for testing this thing out...after welding they got faced off , drilled and reamed for some bushing. I hope to make some better front hubs with ball bearings later on (but most likely I will use these for a long time..LOL)

Re: 777 HAUL TRUCK (1/12 size)
 

Steering design...take 2....

Really wanted to have this all in the body and not under the truck but for now it will work...don't even know how or if this idea will work, needed to do something to test it all out.....(hopefully it will have enough torque for this heavy model)

Re: 777 HAUL TRUCK (1/12 size)
 

Looking Good, If you decide to swap out the rear axle, this an idea to take a gander at.

Cheer's, Neil.

Re: 777 HAUL TRUCK (1/12 size)
 

That would work....if it was a bit smaller or if this truck was a bit bigger...LOL

Re: 777 HAUL TRUCK (1/12 size)
 

Looking good man! I can see that it won't be long now and it will be running! I also know from experience that it sucks to have a truck without a loader so something tells me that the loader will be started pretty soon!

That's a good find Neil. I've never seen one that is that small. Too bad there isn't a place like that in Canada to buy from.

Re: 777 HAUL TRUCK (1/12 size)
 

There is a place here in Canada it's called Princess Auto...well almost...LOL
(don't tell anyone...but I tried this thing out at the shop today....HEEHEE..)
