Do you have any other drawings than that you get from the CAT site? They use there only the same 320 drawings and just different dimensions. I was looking for 390dl drawings and found that only in asian sites are the real drawings.

I only have this from Caterpillar Japanise site: http://japan.cat.com/cda/files/2850741/1/374DL.pdf

Looks so nice, keep it coming! :)

Time to shelf this project for the summer and make more grader videos. :)

Good job!

Are you making every part individually in CAD and hoping that everything fits together well or you make a assembly before cutting and check design mistakes? Could you post a picture of it?

You said that you didn't find tracks wide enough, what is the width of yours then?

The tracks that I'm planning to use are 64 mm wide.

I need to start saving for that cnc conversion... and some schooling:o

Love that precision and finishing touch. Great job and engeneering! A "must follow" one!

sweet build. love watching these builds like this.

Was it made from one piece or several put together? Very good job indeed!

I was wondering that have you tried this CAD program: http://www.ptc.com/products/creo-ele...eling-express/
It has got free trial with some limited functions but you can do pretty easily great stuff and also assemblies. I have been working with Solidworks but I can say that this is for a free copy very good, not so advanced but still great.

What CAM program are you using?

I started to make the bucket for the 374. It's going to be an extreme duty (XD) bucket as Cat calls it. It will have alot of wear plates and four teeth.
It's 140 mm wide in 1:14 scale and in real life almost 2 meters wide.

WOW thats impressive!! Looks great so far!

going to be a big digger if that a 1/10 scale :eek:

that's a pretty serious bucket... and your version seems to mirror it pretty well.

Good work.

Are those going to be the actual teeth or are you using them as adapter so you can use different styles of teeth?

I'm afraid those are the teeth, I didn't go so far that I make separate tips for them:o

The bucket is almost done. I still must braze some of the seams with Durafix.

Wow, how long did it take to make these bucket teeth?

Could you post some pictures or videos how did you make them?

He

Thats looking realy good will cut int the gount very well from the look of those teeth.

Here's some pictures of the teeth. Making them took about a day :eek:
Unfortunately no videos.

They look good, I was just asking because if those were going to be adapters you definitely had my attention as to how you were going to make teeth to go over them.

You are doing an amazing job on this just as you did on the grader and I really enjoy seeing what you machine out next.

Travis

That bucket is so awesome! Now make another for my 850D!

I started to build the upper frame. First I made the center assembly.
In the last picture you can get some idea of the size of this thing by comparing it to the 5 inch floor boards.

Hi

Looking great the size of it is big.
Thanks for posting pics of your build.
Hope all goes well and look forward to see progress.

Thanks

Regards

Mark

Ooh, that's purdy! Nice work.
Cheer's, Neil.

Looks fantastic Ari I am really liking this build.

Travis

I'm flat out speechless! I don't know what to say. I'm not sure there is a word in the human vocabulary that really does this build justice.

Outstanding work! How many kilos does it weight?

So far it weighs 5 kilos. I'm trying to make the undercarriage and upper frame as heavy as possible to keep it steady while digging.

looks great so far Ari :eek: It's making me want to jump on my 385CL thats on the drawing board :eek:

I started to make the undercarriage. First parts are the inner plates. In the pictures you can see the drive mechanism. There will be more support bearings for the axles.
