jeep?

here in NZ we call them trucks, jeeps are a little 4x4 .

Re: JBC limited NZ
 

Nice truck Andy. Your "dolly" trailer is also called a jeep here in the states.

Re: JBC limited NZ
 

Sorry my bad. I guess you learn something new everyday.
And thanks for the comments, I like my little jeep. LOL.
cheers andy.

Re: JBC limited NZ
 

the reason I was confused was I thought this may have been in the video. boss likes his off roading a little too much.

Re: JBC limited NZ
 

a quick update.
the dozer has been stripped and I have made tensioners for the tracks.
just a tube inside the track body with some heavy springs, seems to work nicely.
made up some brass wheels and these need bearings fitted, but for testing a bolt will work short term.
also widened the the track body by 30mm for some extra clearance form the body to avoid rocks getting jammed between tracks and pannel work.
also modified the blade and made some new arms for the blade.
next i will redo the tracks with some new pads.
then it will all be stripped again and sand blasted and a new paint job.
later on I will replace the rams with faster acting ones.
its 4:50 in the morning so that will do for now.

cheers andy

Re: JBC limited NZ
 

had a bit of spare time tonight so,
all wheels fitted with bearings, made a bit of a stuff up and predrilled wheels and body and used 8mm bolts to hold it all together, the bearings im useing are 5mm centers, problem sloved by tigging some pannel washers to body.
also cheated a little and fitted teflon runners for tracks , and added a cutting edge to the blade.
Im going to redo the ripper set up as I think it looks rubbish.
got a fear bit of clean up to do with the dremmel and a bit of sanding but its getting there.

any way picts of tonights efforts.

Re: JBC limited NZ
 

I don't think I have ever seen a vid of this dozer pushing? :thinking: It looks like it'll mover a mountain!

You don't get snow there... why the sandbox in the shed? Your toys are getting too big for that! Time to get busy building a construction park outside in the wide open.

Re: JBC limited NZ
 

We have had snow once. As for cold and wet we do that well.
I do agree with moving outside. I have about 100 square meters planned for a play area.
in the comming weeks I will make a start.
have just finnished the ripper and I start my days off tomorrow so will do a video of the dozer getting dirty before I paint it.

Re: JBC limited NZ
 

weather was pretty average today so I made an executive decision and painted the dozer, here's a couple of pictures showing the travel of the ripper.
I will be making a new blade set up and going with a large single ripper in stead of the three blade set up.
I have run out of paint so off to get some more made up, will pick up some more aluminium and do some new track pads, they will be 15mm wider than the original ones, so traction wont be an issue, these will be nut and bolt , no more pop rivets.

Re: JBC limited NZ
 

Hi Andy, I think you have alot of energy on tap. Just wondering have you been able to pull that dirt bike out and ride it lately?

David

Re: JBC limited NZ
 

I love the paint box, I built a drying /oven a while ago to speed up drying time and now that the paint is dry I can continue the build.

not sure on the black blade? also going to cut it so that it can be moved with two more rams.

the wife picked up a new driver for the dozer, not sure he gets on well with bob the truck driver .
as for the dirt bike I sold my Yamaha TRX 850 a while ago, too many speeding tickets , but I replaced it with a Yamaha WR 450 so technically I can ride a dirt bike most days, usually on one wheel on the way to work .
back to building.

cheers andy

Re: JBC limited NZ
 

Andy, don't like the black blade sorry, just my opinion. But I do like those two yz's and your truck is very cool.

Re: JBC limited NZ
 

Im with you on the black blade. It is gone tomorrow.
Almost finnished the cab. All steel with windows.

Re: JBC limited NZ
 

its been a few years now since CAT changed the color scheme on dozers and skidders.
Nightshift operators complained of glare from the hood and blade on dozers. That's when Cat started painting the top of hood and backside of blade black.Same with skidders, top of hood black and the grapple boom and arch black to minimize glare.
No need to worry with RC's about glare and no matter what you choose it will be right and look great. Nice work :cool:

Mario

Re: JBC limited NZ
 

cheers Mario,
I don't like the black, my youngest thought it would look cool, we have changed our minds but will do the hood a mat black and blade cat yellow.
the cab is almost done and needs windows fitted, a roof and roll bar set up.
the leds have turned up so that's another job to do, then rewire .

should be finished by Christmas....

http://i1322.photobucket.com/albums/...ps72315512.jpg

Re: JBC limited NZ
 

got a bit more done, still need to do the hood and finnish painting the cab black,
dirt biking today so wont have anytime to finnish this week,
soon.

heres a picture for all the black blade haters, myself included.

Re: JBC limited NZ
 

got home from dirt biking and was shown this.
the young fella has been busy, hes covered in paint but a pretty good job.
he can paint the next model. Im impressed.

Re: JBC limited NZ
 

Tell him good job for me Andy, that thing looks awsome!! now its time to move dirt.

Re: JBC limited NZ
 

Forgot to mention that blade looks so much better.

David

Re: JBC limited NZ
 

just a quick photo of the dozer in its natural enviroment, still need to do the lights and finnish the tracks.
but it pushes and runs way better, will get some video up soon on days off.

Re: JBC limited NZ
 

just a couple of the dozer next to a bruder to see size comparison

http://i1322.photobucket.com/albums/...psd4ee734a.jpg

http://i1322.photobucket.com/albums/...ps36d42c6f.jpg


a bit more to do , but night shift so blade tilt rams to fit, LEDs to finish and complete the tracks, then its video time.

Re: JBC limited NZ
 

:update:

here's a quick video of the dozer in gravel, clearing the new site for some summer digging.
need to make a few roads for the trucks to transport the loader and excavator.
need to finish a few things , like faster rams and paint .
Ripper needs replacing but that's another night shift.

Re: JBC limited NZ
 

Nice Andy,

that Dozer can push rock with ease!! It must have some good weight to it.

Re: JBC limited NZ
 

Andyathome-I wish you would think about something before you change the blade lift speed. I think the speed is good. A lot of dozers you see on here are jerking the blade up & down 1/4" and that is not realistic. You will never see a full size dozer with that extreme blade movement. When I watch a video of a model I like to see good, steady realistic movements of the entire machine and I think your dozer does that. All the video of real machines that I have watched the blade movement is so slight that you can hardly see it move while they are pushing. You can not do that with fast movements of the blade on a model. Your scale look is off a little with the very high sprocket (was there a reason for this), but I will take a model that works good over a model that looks good anytime and yours certainly seems to work great. Your model looks good, I was just talking from a scale point of view. It pushes the rock & gravel with very little effort and it will be interesting to see it in the dirt. Nice work, keep at it.

Re: JBC limited NZ
 

hi modelman,
unless santa brings me some more rams ( not likely) I will be keeping the slow ones.
after a bit of practice we are getting used to them and when to activate them to achieve what we want the dozer to do, I weighs in just under 35kg with a 6500ma lipo battery and has a few issues in the pit, If we push too much dirt it digs a hole with the tracks, so soft dirt will be a challenge.
just need to change our driving style, or wider tracks.
as for the track sprocket height, with the type of motor gear box I have that is as low as I can get the drive sprocket, just a space issue inside the dozer, I could have made it longer and wider to get the right look, but then its not going to fit on the trucks and will be way too big.
for the time being the kids are enjoying them selves and it pushes good.
I still have about 8 feet of track leftover so might build one for me and try to do it more scale, once I finish of all other rc projects and anything else the wife comes up with .
at the moment this is still a hobby and hasn't become an obsession yet but I can see it happening. LOL..

cheers andy

Re: JBC limited NZ
 

had a bit of time to replace the ripper.
found some good sized bits of aluminium in the junk pile and come up with this, in picture it is fully extended down, in the up position it has about 50mm / 2 inches of ground clearance.
the paint is drying and should be dry for the official test run tommorow,

I want to make up a couple of covers for the cables on the blade tilt rams and then the dozer will be finnished. ;)

Re: JBC limited NZ
 

well today Im home alone, that can only mean one thing,"play time".
heres a couple of pictures and a video to follow.
I have finished the ripper for the dozer and have tested it out, may make some changes later , but for now it works.
have started to clear an area for some summer digging but am finding 10 to 12 inches of hard packed gravel. the previous owner used to park his truck in the spot I want to dig!!!
will test the excavator.
I have some new rams to fit to the excavator, and a few access roads to make.
SWEET!!!

Re: JBC limited NZ
 

Nice Andy! The dozer looks like areal beast from that angle!

Where did you get the tires that are on your truck? I have seen them around the net but I was just wondering if you found a good deal somewhere.

Thanks, Reg

Re: JBC limited NZ
 

and heres the video.

Re: JBC limited NZ
 

cheers Reg.
by the way I think your bruder dozer is awesome. gives me ideas for my one sitting on the shelf.
The tyres on the truck, I think I got them from eagle machinery of aliexpress in china, I know they were cheap compared to ebay but its been a while so cant be sure.

cheers andy

Re: JBC limited NZ
 

Would sure like to see pictures and more info on your screener

Re: JBC limited NZ
 

sure, will post some when I finish work.
The screener is made from an old drain pipe with two different size mesh.
I had an old spit roast motor doing nothing and some old aluminium filter frames.
I now have 4 speed controls, $10 each.
1 for drum speed, 2 for conveyors and 1 for the vibrator motor that is fitted to the infeed hopper.
I made up a control box and fitted a 12v power supply and a 230v supply for the spit motor.
It runs nice and quiet unless there is nothing in the hopper.

There is a quick video on the first or second page of this post, will do some more videos with excavator and screener on my days off.

cheers andy

Re: JBC limited NZ
 

here's a few pictures of the trommel and a quick video of the gold trommel.
I gutted the black power supply and fitted the board into the main control box, have used banana plugs for the conveyors and motors so it can be transported easily, will one day make the control box into a container so it looks like a generator setup , but that's another job.
the gold trommel uses a portable shower pump 12v to cycle the water but it needs more flow so will look for a high flow pump to replace it one day.
The kids grab some brass dust of the lathe and sprinkle it in the slues box and instant gold.
shame its not worth much but looks good.:D

Re: JBC limited NZ
 

Thanks for the screen pictures didn't realize it was sluice too. You just need to get where there's gold.

Re: JBC limited NZ
 

I have a screening plant for the dirt , that is the one in the photos and another trommel for the gravel, that one is used with water and finds large amounts of useless fake gold.:o

cheers andy

Re: JBC limited NZ
 

heres a real quick video of the screening plant being fed by the excavator, need to make a new coupling for motor on the sluice plant and will do a video, after xmas as way too many jobs need doing in two days.

cheers andy

Re: JBC limited NZ
 

way too hot today, had to stop spraying and spend some time in the shed.
dragged the roller off the shelf and fitted some electrics and had a play.
need ball joints for the steering , add some BBs to the rear wheels and make some body mounts.
Will probably mount the steering servo upside down and cover large hole in front of roller.


http://youtu.be/YuYsnmunlG8

Re: JBC limited NZ
 

is the drum powered or just the rear wheels.

Re: JBC limited NZ
 

This was just a quick build of scrap parts so only rear wheels are powered and no vibrator in roller drum.

Re: JBC limited NZ
 

heres a build of the roller Ive posted on an ausie site, didn't save any picts
