Looks like you're movin' on up in the world, JasonCool . Its looking really good too. That undercarriage is superbly fabricated. Applause

Here is a look at the body on its new tracks









Now I am off to mold my track for the machine. I am doing a different looking design Eric talked me into this design
It will not be a smooth crane pad

Sometimes it pays to know people.

I have about 24 hours in the under carriage so far

"Build of the year 2013" will be a though one to decide next year, it is not even April and there are lots of really awesome builds already. But this one will probably be among the very top! Simply fantastic.

Thanks for the great comment Iputting everything I can into this build. I have been building for 8 years this month I think I have come a long way since my first crane cage build. I hope to inspire more builders out there to push themselves.

Well not much progress if you look at it but there is about 5 hours work in the rollers. 30 rollers 4 pieces each all were drawn up and laser cut then glued and drilled. I wanted to have a nice free rolling track system so I incorporated tje working rollers.

few pics







I have the track mold finished first cast is in the pot about to go pull it so we'll see how good it comes out

Brandon the CC6800 has been postponed for a while. I have grow into a better builder since that will start it back up one of these months.

Ok been casting track pads what seems like forever now just about 130 of them. Each track takes 63 of them, each track had to be demolded , cut off the spurs and pouring gates, hand drill the hinges and then pinned together. I am sick of seeing tracks for a while.......but man does it look good

I have done some of the hydraulic hoses aswell and these are a real pain to do but the detail in them makes the model better

An those of you who have the big demolition excavator the HItachi EX1000 well this is what it looks like next to the R300D.

Thanks Eric for the great tracks

Fully extended


Making the 1000 feel even smaller


Closer look at the 2


Both booms layed down


New tracks a lot taller then the 1280 tracks


I will get a pic with the short boom set up in a bit, hope you are enjoying the build

This is just an incredible build! You are a "model" GOD among men! Forget build of the year, build of the decade. I'm just in awe.

Outstanding Jason! Maybe I missed it earlier but what color will the body get? Will it have a company livery. The level of detail on this monster reminds me of the Kobelco 3500, at a lot less of the cost I would imagine. Thread of the year for me so far!

Jason,

It looks great. The hydraulic hoses are incredible. What did you make them out of and what diameter are they? How do you make the molds with so much detail?

Thanks,

Ed

ok...i was waiting for the tracks to comment.... i know i dont post much anymore and i guess ill be the guy to say it..........HOLY **** !!!!! thats without a doubt one of the best sctratch building projects ive ever seen. i wouldnt have the time or desire to ever attempt anything close to that. the detail is flat out insane and you built every part...nothing borrowed. not really sure what else to add.....nice work jason.

Looks amazing Jason - attention to detail and finishing of the plastic is very good, especially considering the scale, and the tracks look great. Will be nice to see it when it's all painted up. Applause

Thank you everyone for the comments once again. I think I have close to 500 hours into thiss as of right now.
As for the great detail in my moldes it pays to use a high dollar silicone, and most important is to have the master perfect and set up perfect in the mold. Mold making is a art work all in its self.

I have some pics of the the machine with the short boom attached just need to update load them but I had to go to work today so will have to wait.

I still have not thought of a color still up in the air, might just leave it all primerd'oh!

I am also in talks of casting this as a model to sell, but we are a long ways off but you could see this offered still not out of the question

As of right now I am redesigning the cab, well not the cab but the way it attaches to the machine. The way I had it the cab was to high for transport so I am doing something you have not seen on a crawler , you will have to wait a few days til I get it perfected and installed


Thanks again
Jason
