Pricy lil buggers! Quite an investment in tools to make these cheap models, eh? :p

Re: CAT 374D L
 

LOL . I'm doing my micro mill shopping right now :eek:

looks great Ari . did you make 2 extra of each panel ;) ?

Re: CAT 374D L
 

WOW!!! Awesome work Ari!!! Its really coming together! Keep up the killer work!

Re: CAT 374D L
 

I have been away for a while had to reread this one and it is as beautiful as the grader. Excellent progress. :D

Re: CAT 374D L
 

It's coming along nicely Ari! I'm waiting impatiently to see it win build of the month/year!;)

Re: CAT 374D L
 

truly amazing.

Re: CAT 374D L
 

:eek::eek::eek:

Re: CAT 374D L
 

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

Re: CAT 374D L

Re: CAT 374D L
 

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!
Reg

Re: CAT 374D L
 

I'm using Jung pump and Kampfer valves: http://www.123modellbau.de/modules/w...7&cat_id=52019

Re: CAT 374D L
 

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

**edit**

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

Re: CAT 374D L
 

Ari I have worked on Cat machinery for about 15 yrs and I must say your detail is fantastic keep up the good work I cant wait for the finished product

Re: CAT 374D L
 

Thanks guys:)

Here's what I got done today:

Re: CAT 374D L
 

are you milling those square holes on engine doors and anti skid plates?
With 1mm end mill or??

Re: CAT 374D L
 

Parts, parts, parts... so excellent!!!!

Ari, did you plan the complete support structure for the panels in advance or do you decide as you go along?

Re: CAT 374D L
 

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.

Re: CAT 374D L
 

Oh :o, 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??

The attention to detail is amazing!

Re: CAT 374D L
 

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!

Re: CAT 374D L
 

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

Re: CAT 374D L
 

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

Re: CAT 374D L
 

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:)

Re: CAT 374D L
 

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

Re: CAT 374D L
 

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:confused:
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:)

Re: CAT 374D L
 

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 .

Re: CAT 374D L
 

Hi

What a great model your attention to detail is amazing, thanks for sharing with us all, looking forwards to seen this progress.

Regards

Mark

Re: CAT 374D L
 

Yes I did. They will send you a invoice to your email and you must pay that in advance.
It's simple to do in Europe when using those IBAN and BIC numbers but I don't know if are you able to use them when paying from outside EU.

Re: CAT 374D L
 

OK I'll try them again . worst case I cut them myself . I already have it programmed . It's just a good couple hours to cut in the mill in steel .

Re: CAT 374D L
 

This is the greatest build ever. This machine is going to awsome...

Re: CAT 374D L
 

Slow progress:)

Re: CAT 374D L
 

WOW i am sooooooo jelious. such awsome work it just blows me away wow!!!!

Re: CAT 374D L
 

I got the hydraulic system up and running to test leaks and found one on the stick cylinder tubing:o I fix that and made a little video of the test run.
There's 7,2 kg weight on the bucket and it seems to have much more lifting capasity, all though it need lot of counter weight:)

http://youtu.be/M9QHtM6sdxI

Re: CAT 374D L
 

will you manage counterweight made in alu or have to do in steel?
Good looking steps.
Guess by now that you are an expert on programing!
Dan

Re: CAT 374D L
 

Finally its moving! :)

Not to bad with only one leak, looks very smooth in the hydraulics!

Re: CAT 374D L
 

Just one leak?! ..that's pretty good on start up. :) The real test will be when you're working the snott out of it for a couple hours straight, maxing the pressure constantly! :D

Re: CAT 374D L
 

if you need anyone in the UK to order stuff and forward it on, then let me know, don't mind helping fellow modellers out..

Elliot

Re: CAT 374D L
 

I'll keep that in mind Elliot :) thanks for the offer . I found a co. state side that has 1 in stock . Same price when converted .

great job so far Ari :) your truly an inspiration for me to get my but in gear and get 1 of mine done :)

Re: CAT 374D L
 

I propably must put led inside:)
I would have never believe that this thing can have so much power, I was just lifting a full size car tire with steel rim which propably weighs around 20kg:eek: and it didn't even struggle.

Re: CAT 374D L
 

That's a bit extreme, what do you have the pressure set to?
