I started to make the lower carrier rollers. First I made the brackets (32 pcs) and now I should made the rollers (16 pcs) I wish I had a cnc lathe

[Madda]

Are you making these rollers with mill or lathe? I know that feeling when you have to make manually same thing for numerous times. I once drilled manually over 1500 holes...


But the build is still very cool and yet fast.

What size screws are you using there?

[Hemi1966]

Madda, those rollers will be made with lathe.
The screws are M2 steel ones. It was a quite job to make threads for all the 64 holes with three separate taps. The 2 mm tap doesn't take much to brake.

[Hemi1966]

Finally got all of the carrier rollers done including the upper ones

Pretty much yes, of course all axles and pins are steel. Also the upper frame swing bearing mechanism will be made out of steel. There will also be some brass parts in the upper frame.

This is one awesome build, Ari. It's going to be heavy and durable in the end.

Great work. Another beautiful job.

I started to build the undercarriage x-frame It will be possible to narrow the undercarriage for transport like in the real thing, just have to unscrew 48 bolts
I also found a nice picture of 374 beeing transported on a low loader

The pace you are building at is just amazing!

How many hours a day do you spend on that beast?

Too many

[MitzuRazing]

Cnc is cool

[plow jockey]

Wow !! Your work is amazing. Excellent work !!

[Hemi1966]

Got the x-frame top piece and the underside corner support pieces done. I also made the boom tip reinforcement plates

[RCP57]

When I look at your update pictures I start dropping F bombs... In a good way of course. There's just not that many polite ways to describe what you're doing!

Nice work Ari!!!!!!!!!!

looks really nice, how much does your undercarriage weigh?

Thanks again guys for the compliments

The undercarriage weight is now about 7 kg, that's without the tracks so it probably will be 10 kg when finished.

[Madda]

Great!

How are going to solve the problem what comes when you need to connect drive motors with the ESC? I mean that the swinging is going to twist the wires.


First tesdrive shouldn't be too far heh?

I'm going to use slip ring like these: http://www.hzqs.com/english/src.html

And what comes to the undercarriage test drive the only thing that's missing are the tracks
