Wow that looks amazing. The tracks seem very smooth and track great. I can't wait to see the rest of the machine come together.

great job , Ari If your around 64.25 mm you should be good for the wide shoes .

I did some work with the stick today

[speedy8305]

I must say that is looking awesome cant wait to see the finished product will be something to see

Awesome work on the stick and your undercarriage! Speaking of track pads. How long are your track pads?

64.25mm sounds good. That's after the 900mm(35inch) track pads scaled down? That's what I'm doing and added just a little more. The track pads I made are 66.00mm wide and 19.70mm long. After the 900mm pads for my 390.

Do you know the actual size of a 900mm width track pad for a 374? Length wise? Is it the same between 374 and 390?

Thanks
Jeff

I made mine wider, they are actually 80mm wide. I don't like the look of an large excavator that has narrow tracks
But seriously, I might cut them shorter later.
I've seen pictures of 374 that has maybe over 1 meter wide pads

I don't know the exact lenght of the pad, but mine are 20mm long.

Everything is looking like it's coming together nicely. As far as the track width; It would depend on what the machine is going to be working on. Narrow tracks shorter frames for hard rock where no flotation is needed.

I Know the 385 ( which I'm building (2)) are 900mm (36")and 750mm (30") I'm making my shoes @ 64.25mm x about 19-20 mm .75" . I read somewhere that the 390 is just a renumbered 385 with a few added HP , etc

[Hemi1966]

I started to make the cylinders

[Azonic]

That looks very nice!

I would go for a little narrower track pads, other then that its a piece of art!

I've come to that conclusion too, I will make them slightly narrower
