Re: Mack DM truck, scale 1/24

The rears are doing quite well actually. But there is too much weight on them and too little on the front axle. maybe I can move the fifth wheel a bit forward.

Re: Mack DM truck, scale 1/24

I decided to add a low loader NYC 90's style, like Malbros and Confortti had to haul big crawlers like the 4100W around town. I am using parts of disused projects to build it. I just finished the...

Re: Euclid R-62 dump truck

It took me just under 2 years to build this truck. It was a lot of fun. The transmission and the controls were the most challenging, but after a lot of tinkering it all works and it is fully remote...

Re: Euclid R-62 dump truck

I found the right paint for the Euc. It looks decent, the color is very nice but needs a second coat and I didn't buy enough!! That means waiting.

Re: Euclid R-62 dump truck

With the current gear ratio top speed in scale 1/1 is around 25 mph. The real one can reach about 30 mph.
The electric motor should reach 5,500 rpm, while the diesels do 2,100 rpm.

Re: Euclid R-62 dump truck

I added another motor. It might be overkill and it is easy to take it away. I can also easily change the reduction between motors and gearbox. Now it is 1:4. I tried it with the battery with a much...

Re: Euclid R-62 dump truck

Thanks,

I hope to fix the problem by increasing the reduction between the motor and the gearbox by 20 to 30% and i will create space for another motor. If the reduction doesn't do it, an extra...

Re: Euclid R-62 dump truck

Today I did my first test run and I took a short video.
It is a 4-speed power-shift and the first and second speed work nicely. The third works OK, but the fourth speed seems to take all the power....

Re: Euclid R-62 dump truck

Due to the crisis I have lots of time for the gearbox. It slowly comes together. I finalized the input and output sides. I hadn't thought about these at all when I started building the gearbox, so...

The original comes with a whole lot of options. I choose for
the first gear a 5.50 reduction,
the second a 3.20 reduction.
the third a 1.75 reduction and
the fourth is a 0.93 overdrive.

Re: Liebherr LTM1800 scale 1/24

The one thing missing was the extra drum mounted on the boom when using both the derrick and the luffing jib. I managed to put the gearmotor (60rpm) inside the drum. It fitted beautifully! Today was...
