[9W Monighan]

Wow,coming along nicely. The wear plates and teeth on the bucket turned out very nice.

[Azonic]

Looks great, nice work as always!

[Stefan]

Very nice parts, Ari! The pace of your build is amazing.

Where did you get that chain from?

Another fine job you are doing there........Conrad has alot of nice building stuff, but they dont ship to the U.S. of A

[Stefan]

Impressing as always! But it looks like you let the chain actually slide against the housing walls? Never seen that before. Don´t you think that will create noise and an aluminum slurry?

Yep, your right about that Stefan. Due a small design error I made the housing little too small, but it doesn't keep any noise and hopefully with some grease inside it don't eat it self thru the housing

[Stefan]

I see, its a bug and not a feature Well, in any case, the chain plates might dig in a millimeter or so (actually half a millimeter if you have the 6 mm pitched chains), but then the rollers start rolling on the land between the grooves and the wear rate should decrease.

[Hemi1966]

Some progress with the undercarriage. The drive end is pretty much done but the front idler still needs to be done.

[RCP57]

Sweet! You'll be digging in no time!

Do you have any more pictures of that motor cover or whatever is that called? You bent that radius or milled?

That's actually a U-profile that's machined that way.

Got the idler wheel and track tension mechanism done

[Hemi1966]

Some progress

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.
