Re: Cat 340D Excavator build
That’s absolutely amazing ! Can’t believe the progress your making and now I feel like I’m slacking 😂
Are you going to swap the motors out for faster ones and test ?
Looking really good

Re: Newbie Scratch Build - D575A Dozer
Yes these are the ones I’ll be looking at getting when the time arrives. I’m not sure if I need to go for the 5mm fittings or the standard small 3mm yet or to have one value each for the front...

Re: Cat 340D Excavator build
Its coming along nicely!
any reason for using aluminium?
how do you know your rams will act fast enough? can you speed them up if required with more voltage?
keep up the good work !

Re: Newbie Scratch Build - D575A Dozer
The sprocket has a 105 mm pitch diameter. I did a crude test with the sprocket straight in the motor and it looked too fast. 🤷🏼♂️

Re: Cat 340D Excavator build
Hi Chris
Excellent idea on the lead screws and workmanship. I’ll be following your build with interest as I think an excavator will be my next project.
Good luck
