140H Grader

[modelman]

rcfarmer-your doing really great work! That model looks very complicated to me but looks like you have it well under control. Nice job!

[Espeefan]

This, your work, is insane, Rob! I cannot believe the painted parts for the blade lift are wood. This is going to be an incredible model, when done. I cannot wait to see what developes.

[rc_farmer]

Thanks again guys. Here are a couple more painted pieces.

Mighty fine craftsmanship Rob and way to use your noodle for materials.

[JAMMER]

You are looking real good Rob. You are starting to make some real hear way. Ed

Here is a brief test the hydraulic steering........hooked it into my terragator pump to test how it should work.

It doesn't seem like it's turning very sharp or is it?

Graders don't turn very sharp but when he leans the wheels it will turn sharper.

Coming along nicely.
What motor rpm,pump pressure and gpm is your pump operating at?

When the wheels are on, you will be able to see the difference in the turning. I am going to use the Leimbach pump. Its only 10 bar. I may have to upgrade to a bigger pump later, but for now, i think this will work. Had to test it......couldn't wait for pump to get hear....., Hopefully it will be here by first of the yr.

i am really liking this build i always liked running the 140's alot better than the 120 this is going to be one cool build

[RCLogger]

WOW very nice Rob ! ! ! You should give me a lesson on soldering, you have it mastered.

How many spools are you going to have in the grader ( functions )

Td9-I have never run any of this equipment before. I just like building different models.....I am building this one from pictures only. So far, I have probably taken about 200 pictures to build each pices.


Greg-6 spools when completely done. After building the Gator, the soldering is a breeze now , don't mind sharing any tips that might help ya
Patience is always the third hand....

I guess I need to pay more attention when I see the municpal grader turn around, I thought they turned quite sharp without leaning the tires.

I wonder if the Mammoth tires will roll on edge, sidewalls might be too soft. Perhaps stuffing the tires with plastic BB's will stiifen up the sidewalls without adding too much weight.


What makes the difference in hyd flow is the size of hyd hose and fittings. What size do you currently have on your Gator Rob? 1.5mm ID?

My current excav & wheel loader are using 2.5mm with the 350ml/min pump and cycle speed is significantly quicker, I would say more than double, than the older models with same pump & 1.5mm hose/fittings.

I do have the 1.5mm ID. Getting all this hydraulic stuff right is the challenging part for me. I appreciate the info of the 2.5mm, which is what i think i need for the grader. I ordered the biggest tank from Leimbach. Good idea on the plastic bb, was going to add some to the rear as well.

Here are some painted pieces. Enjoy!!

[RAIDERS]

Paint came out very nice keep up the good work.

[JAMMER]

Rob that looks real great you have don a excellent job if it looks this good in a picture I can't imagine how good it looks in person. Ed

[td9clyde]

looks down right awsome i like your grader alot i dentical to the one i used to run

[9W Monighan]

That is going together nicely! Can we see a closeup of the grill? That has some nice detail to it.

WOW how did i miss this thread? it looks amazing!!
