140H Grader

[JAMMER]

Rob that grader is really taking shape I like it a lot. Talking about radio the F16 can be made to 2.4GHz and have an extra stick also it dual layered Scale Art told me. It has 15 channels plus 6 in 2 layers the price is 689.70 Euro or $940 US. I guess it will even brush your teeth if you want it to. The only problem with it I can see is if you have a problem with it it has to go to Germany to be fixed. Ed

Hey Ed, i may have to do like FGD......and mount two radios back-to-back for that kind of dough I am figuring things out as i go.

Thanks for the compliments!

Update to the grader pics:













I have started to put some paint on a few pieces....will post more later.

[JAMMER]

Rob your looking good your really coming along slow but sure nice job. Ed

[rc_farmer]

Thanks Ed, yeah its really slow, but it's starting to pickup a lil bit. Some of my parts where i need strength, i build the prototype out of wood then have them water jetted in aluminum......just spent 20 bucks on 2 can of Cat yellow, but it worth it. gonna start ordeing hydraulic parts after Christmas.

Rob I left you a pm. Ed

Joe, i am going to use a chain, sprocket and geared motor. I made the ring and i plan to have the chain tacked welded to the ring. I have a machinest that will make the retainters for the ring to ride on. Thats the current plan. I would like to use the worm gear method like on the real one, but haven't quit figured out to make that work. It would lok more scale than the idea that in my head at the moment.

That's the best way I could figure to do it too. An intertooth gear is very costly for no more than your getting.What size chain are you going to use? I have some stainless 1/8 '' pitch chain that would allow room for the circle shoes to mount.

why not cut your own ring gear and make a smaller one for on the drive motor for it ?

Ideally yes, but i don't machine......have ask about getting one made, but too costly.

I am going with this:

http://2wheelhobbies.com/product_inf...roducts_id=311

I believe this is equievelant to #25 chain

5 spool valve $ 478.00
pump/motor $ 335.00
Airtronics 10 ch $ 429.99 (with nine 3-pos switches) Priceless!

[BigZracingRC]

very good looking build! when do you think it'll be running?

[JAMMER]

Hey Rob when you figure out how to work that 10 channel Airtronics let me know. Ed

[rc_farmer]

Ed, I think the radio might be my one and only Christmas present...

I plan to have it completely working by mid-summer '11

I have come to terms that hydro is only way to go. I have tested the air theory and it just will function like i want it too. Air can't be adjusted.

[JAMMER]

Rob good luck with your endeavor. Every time I think everything is going along smoothly something always through a monkey wrench in the mix. Ed

[johnboyee]

is this hotrod somewhere in the 1/9 to 1/10 scale?

[td9clyde]

lookin good i like this build it is something there isn't alot of keep up the great work

[Finster]

Neat project looks great so far. I had an idea about the internal gear ring. What if you cut a circle the outside diameter you want and put some sheet metal or plastic on the edge so it sticks up the thickness of the gear you want. In the middle of this circle fix a large regular gear that gives the ring gear the right spacing and teeth. So basically make a temporary mold and then pour some strong epoxy type stuff it the space.

Hopefully my description makes some sense, if not I could do a quick drawing for ya. Not sure if this is a better idea then your chain idea, but just throwing it out there. I look forward to your updates.
