Lil bit more on the moldboard assembly. Got the braces done and the cylinder bracket made for the blade's pitch. Gotta clean all the solder up. I will sandblast all the metal before i prime it

I am going with the AT SD10G. I just got the nerve to sprang for a pump though, so the radio will be early next yr, after the holiday season.

Sand, sand, sand, then cover with fiberglass cloth and afix with CA. The CA fills 99.9 % of the cloth......sand, sand, filler, sand, sand.....rub ur fingers across it, then sand some more......then prime/paint

Not sure it is enough channels for you, but all the switches are 3-pos. The F-14 is expandable enough that it would work but with all the decoders it ends being a lot of radio gear.

The circle and moldboard assembly is looking just great! Nice detail, and really like the novel approach to the circle gear - we often don't recognize a chain works from both sides and doesn't have to be the moving part. I agree with the others, how you make wood look like cast-iron is a wonder. Keep it up!

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

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.

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.....:D:D:D, Hopefully it will be here by first of the yr.

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 )

Re: 140H Grader
 
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. :confused:

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.

Re: 140H Grader
 
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 :D, don't mind sharing any tips that might help ya:)
Patience is always the third hand....

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.
