This build started after seeing a European D11 on YouTube and then finding out there was nothing commercially available. This model is 100% scratch built using Auto Cad and Okuma CNC machines. The material is 99.9% aluminium. When it was suggested to build a D11 my Nephew said it would be good to have one as well, so three of them went into production. They will all run Leimbach Hydraulic pumps and valves. The Cylinders are self made.
The radio gear will be Futaba FC16 as I use these on my other construction models with success and are expandable for more functions. The ESC, sound and light units are from Servonaut. When painted Cat Yellow will be the color.
Everyone that knows me, knows at least 2 things. I am a HUGE CAT fan and a HUGE PETERBILT fan. With that said, guys in the hobby have done plenty of versions of the “Peterbilt” some more accurate then others. I will also one day do my own version but now I figured it was time to really put myself on the map and solidify my position in this hobby and show a little of what i cando! I sat around my work bench for a while when it finally hit me. Im going to make the new CAT truck, it has never been done or attempted to my knowledge and the new style body was something that really had to be fabricated from scratch and would be a good candidate for the use of my 3d printed parts. The truck me a total of 107 Hours to complete from start to finish between designing parts, printing, manual labor, paint, and assembly. EVERY single part on this truck was hand made or custom made just for me by me. The rims, steps, rails and tanks were made by Steve at IHB Scale Models, The Exhaust stacks were made by Benny at Fat Stacks. The visor was made for me by Rod at Custom Drop Visors. Everything else was design and manufactured by me in my work shop. I also have to give the guys a Foley Caterpillar in Edison NJ some credit for allowing me to go into their facility to take pictures and measurements for this beautiful truck. I wanted the truck to look exactly like the real deal with a little custom “Exclusive” touch to it. The truck is equipped with lights and sound (MFU). A 3 speed transmission with a 4:1 gear reduction capable of pulling 100+ pounds with ease. The paint and body work was all done in house as well. I wanted to keep the traditional CAT yellow but added a little twist inspired by a proto-type cat I saw on the web. Mudflaps were also done inhouse along with the diamond plate accessories. Every single 3mm /2mm hex head bolt has been replaced with scale miniature bolts including the bolts on the wheels to give the true scale appearance. The rear air lines on the truck are fully functional for sending electrical signals to the trailer for all lights including turn signals and brake lights. The lift/ drop axle is also fully functional being controlled by a servo from the radio to lift and lower on command. I used a turnigy 9xradio because Ive been hearing some good reviews on them and since they are 3-4x cheaper then a spektrum of the same calibur i figured, what the heck let me see what this thing could really do. to my surprise it was solid and got the job done. I will admit, it is definitely not as user friendly as the spektrum but for the price, I didnt mind spending an extra hour or so behind a computer doing ggogle searches. Overall radio impressed me and saved me a few pennies on an already expensive build. That is pretty much the story on the Custom CT 660 CAT truck, with PLENTY more to come.
This model is complete build from scratch Designed on cad. 40% of the parts are laser or CNC cut, the rest is made by hand. 95% of the parts are aluminium, the bucket is from cupper. There are glued together with UHU 300 end-fast. Tires are from Barmhausen, rims are custom made. Lights from Veroma. The ESC and sound module are from Servonaut. The Hydraulic pump is from Jung, with a brushless motor, the valves and cylinders are custom build from brass. pressure around the 20 bar. Every tire have his own RB35 drive motor. The battery is a 3S 4000MHa lipo that gives a 25 min operation time. The radio is a Spectrum dx10t with 6 functions: driving, steering, boom up/down, bucket, sound, hydraulic pump and lights. Some of the parts are made on a 3D printer, like the interior of the cabin and the steps on mudguard's.
Chemical Transport Trailer
The world of model making is my greatest passion. The construction of this tank was commissioned by a friend of mine and was very challenging for me to build. It is based on a real trailer that my friend has. He owns a transport company that utilizes these tanker-trailers and dreamed of owning a scale replica one day. I used the manufacturers blueprints to aid me in my construction. The creation of the tank is completely artisanal; the chassis, toolboxes, suspension, flaps, piping, air-boilers, filling nozzles, ladders, pilots, rails, support legs, and a long list of other items. All with brass sheet in various gauges, round-tube, and square-tube in various sizes. Here is more-or-less the construction step-by-step: http://www.rctruckandconstruction.com/showthread.php?t=9118
