Re: 140H Grader
 

Awesome job. Smooth as silk. I looked at both videos, guess there is a little tweaking to do?? It'll be nice to see it in some loose dirt; watch it roll up a nice windrow.

Re: 140H Grader
 

Thanks guys for the kind words. Yes,i have a little tweeking to do and learn how to drive it :D. I only have one switch that is spring-loaded. It would be nice if all the controls were, but I am happy that i have gotten this far. I may get a chance this wknd to put it in some loose dirt and see what happens.

Again, thanks all!

Re: 140H Grader
 

Learning to drive is difficult, but soooo much fun :D

As you saw, I modified my transmitters' controls for my grader, maybe you could do something similar (it's really not difficult).

But what do you mean with "switch" - aren't you operating most of the functions with proportional sticks?

Cheers
Jens

Re: 140H Grader
 

Bravo! Fabulous work - turned out awesome as usual.

Re: 140H Grader
 

Jens, I am using an Airtronics 10G.....U can assign the functions to any channel that suites your desire. Here is how I have mine cnfigured:

Elev stic=circleboard rotation
Aile stic=Steering
Rud stic=Pump
Thr stic=Throttle

8 different (3 pos switches) that are mixed with the rudder channel to control the pump. The pump only operates when I move a selected function.
Of those 8, only one is spring-loaded....the others are on-stop-on

Re: 140H Grader
 

Thanks Iz,

Re: 140H Grader
 

Ah, okay, I understand now: No proportional control on those channels.
I guess you could solder in different switches, but the Airtronics is a bit too expensive to just try it...

Re: 140H Grader
 

rc farmer-I really like the way this model turned out and the detail work is just incredible. I enjoyed the videos also. I have a question for you or anyone who can answer it. What is the advantage of leaning over the front tires while scraping? I have watched scrapers work and doing this but I never knew why.

Re: 140H Grader
 

The wheels lean to counter act the blade pushing the front tires sideways,"Lean into the work" It also makes it easier to turn tighter.

Re: 140H Grader
 

Wheel lean helps counter act side draft or force from the moldboard.
Lean the wheels toward the heel or lagging end in most grading.
Look around and you will see people who are clueless on a grader.
Think of it as digging in your heel to fight the tug of war, dragging your toes doesn't work
As well. Later, Neil#2 aka doodlebug.
Hey 9w, I can't type as fast on the phone lol!

Re: 140H Grader
 

Incredible machine! VERY nice work.

It very realistically simulates the full scale machine in both form and function. It will be a treat to see it push dirt.

Re: 140H Grader
 

When I presented my grader model at a recent show here in England, the most common question was "Do the wheels lean?" :D And I said "Yup!" =)
So, obviously people notice it as something characteristic - and I was glad that I had decided to realise this function on the model.

Re: 140H Grader
 

Almost done...

Re: 140H Grader
 

Very impressive, both in detail and in size :)
The interior is positively crazy! :)

Re: 140H Grader
 

excellent top notch finish

what did the CAT dealer have to say

Re: 140H Grader
 

The Cat Personnel have been very supportive. The want to put a write-up in the compnay news letter. I am also planning a trip to the 14M factory down in Little Rock, which is about 2 hrs from me. I think that will be exciting.

It's time to start the testing phase. I noticed the discussion about the blade and the circle board being able to hold. Mine will have to cut loose dirt....as i used the same setup on the worm gear.....only difference is my box is made of wood. When i find me another machinest, i will get the gearbox made correctly.

Re: 140H Grader
 

Robert,
All is can say is,INCREDIBLE,you have pulled another rabbit out of the hat.
AWESOME.

Chris

Re: 140H Grader
 

Rob,
This has got to be your best and most impressive build to date:eek: You need to get some pics of it next to the real thing. Please let us know what the people at the Cat factory think of it.

OH ya, PLEASE don't break it before Indy!! I really want to see it run!

Re: 140H Grader
 

Rob, YOU KILLED THIS THING Man that is nice, can't wait to see it.

Re: 140H Grader
 

Thanks Joe,
I take notes form the best. I have been doing some field-testing before I finally release it. Tweeking a couple of things to make it a lil more durable.

Re: 140H Grader
 

Thanks Lynn, I plan to have it at Indy.

Re: 140H Grader
 

Thanks Trucker47. was a long project, but i'm pretty proud of the outcome so far.

Re: 140H Grader
 

You are a true artist!
All I can say is WOW:eek::eek::eek:

Re: 140H Grader
 

Rob you did a beautiful job on that grader it looks real and to think some of it is wood you never know it. Spectacular job. Ed

Re: 140H Grader
 

That is one sick looking machine very impressive can't wait to see the finished product.
Hammer

Re: 140H Grader
 

What do you cover the wood with?, Bondo, gel-coat?

Re: 140H Grader
 

Sneaky-pete, thanks for the complments

Jammer, I appreciate the helpful information on parts to make this model possible.

Hammer, I should be putting the step ladder on today and she will be finished......WHEW!!!!:D

Cbazq271, To prep it, i used a balsa filler called Hobby-Lite. The filler is easy to use and contours very well. That sealed all the cracks and holes. I used a wood sealer/primer for base coat, then the Cat yellow........oh i almost forgot, 1st thing was to sand, sand,sand, sand up to and including the primer. :D

Re: 140H Grader
 

turned out great

Finished Grader

Re: 140H Grader
 

:eek: Rob first glance of the 1st pic , I thought it was the real 1 :eek: looks great , another great build by you :)

Re: 140H Grader
 

WOW I too thought the first few pics were of the 1:1 for comparison sake. You nailed it. Great Job.

Re: 140H Grader
 

Rob, Your grader build is awesome and knowing how it was built is amazing. Great work from a very skilled builder. We need one more picture though, you standing proudly beside it so we can see how big the model actually is.
Rob

Re: 140H Grader
 

Another outstanding build from an outstanding builder:D:D Unless someone knows, you would never guess there is wood under some of that paint.

Re: 140H Grader
 

Love that grader, top shelf work if ya ask me.

Nice job :cool::cool:

Re: 140H Grader
 

Great :)
And I mean "great" - not "great considering it's wood" :)

I'd love a play area like this close by #sigh#

Cheers
Jens

Re: 140H Grader
 

All I can say is "WOW"

Re: 140H Grader
 

rc farmer-the model looks great and all systems seem to work flawlessly! Sit down and have a cold one. You deserve it!!
