I've been following several builds on the site and I'm amazed at the talent and skill shown. Thank-you for sharing.

Some progress with the upper body

Looks amazing Ari! I'm not sure if I missed the info but what are you using for the hydraulic pump and valves? Are you going to make your own?

Keep up the great work!

Very very interesting build. what pressure will the hydraulics run at?

**edit**

Just seen it, 20 bar. Should have some good digging power

Those square holes are milled with 1.5mm tool and skid the plates with 3mm radius mill.

I had some vision in my mind but it often changes on the way

Got the rest of the anti-skid plates done and also the hinged center section of the engine cover.

Oh , now when changes glasses I can see the radius on the square holes. Looks familiar with holes on my hood, guess they have same supplier there.
What speed can you go with a 1,5mm mill? 4"/min??

Wow. I am at a loss for words. This is another great Caterpillar model, built with incredible detail. A work of art, that will really work, when done!

[Newcastle]

Hi. Great build. What kind of rpm are you looking from your motors after the reduction?

[tracksntreadslou]

Coming along Nicley Ari ..Your attention to detai is awsome ..Pretty much giving it your own signature with all the little changes ,extras and add ons ..When your milling out the smaller holes can you pretty much cut through the thinner guage material or do you have to make multi passes with those fine bits..Feed rates make a difference as well? Thanks Ari and Nice work

With those smaller bits I like to take several small passes with a higher feed rate.

Today I managed to make the upper cooler grill

Looks fantastic Ari! It won't be long now!

Thanks Reg, I hoping to get the hydraulics up and running in few weeks, just missing filters and the tank.
I'm anxious to see how my cylinder will hold the pressure
To be honest there's still a lot to do, and it always seems to get harder and harder towards the end.

Here's the lower grill

awesome job so far Ari . Question, did you order your internal gear online ? The site states they only except online payments from the UK . And of course , the 1's I need are not in stock .
