Hemi
Superb workmanship and really inspirational project. I have question on your homemade cylinders. Do you use a specific steel for the rod, ie precision ground drill rod, or regular steel? Also what type of oring? Silicone? Viton? I really want to try to make a working cylinder for a dozer.

Love the grader - masterpiece!
Best regards,
Bob

Re: CAT 14M3 Motor Grader
 

This build is AMAZING! This will be super cool when everything is done & this masterpiece is moving dirt.

Re: CAT 14M3 Motor Grader
 

Thanks Bob.
For the rods I use 1.4021 stainless steel. I'm using both Nitrile and Viton o-rings.

Re: CAT 14M3 Motor Grader
 

I got the drawbar in place. :)

Nice work as usual Ari!

Re: CAT 14M3 Motor Grader
 

Great job you are doing here Hemi ! May i ask what type/grade of aluminium you machine ? I want to use 6061-t6 for my project but maybe you have a better alternative ?

Re: CAT 14M3 Motor Grader
 

I'm mostly using 6061, but I also have some harder aluminium that I have no idea what it is.

Re: CAT 14M3 Motor Grader
 

I've been working with the circle gear, and I got it almost machined when it came loose off the chuck. I could not tighten the chuck very tight because the circle gear is not very thick. I was taking very moderate cuts and relatively slow speed, but it was not enough :mad:
I have to try again, and do the final operation with different mounting method.
Luckily some parts turn out decently.

Re: CAT 14M3 Motor Grader
 

That's a sad let down! The part looked like it would have been beautiful, before the catastrophe.

Re: CAT 14M3 Motor Grader
 

Bummer:mad: I know the feeling when a part comes out. I've had big parts that I'm getting paid for come out of my setups running the endmill across it making pretty tooth marks every 1/4" :rolleyes: because I'm usually climb milling.
On your piece; Could you cast it in some of that Bismuth alloy?
If you don't know what that is, it's a soft lead type metal that melts in hot water.

Re: CAT 14M3 Motor Grader
 

Success on the second attempt :)

Excellent job Ari you are a real artist with your Graders. Ed

Re: CAT 14M3 Motor Grader
 

Glad it worked out for you second time around! Looks beautiful!

Re: CAT 14M3 Motor Grader
 

Thanks guys :)
I got the centershift cylinder and few brackets done.

On the last pictures you can see some extreme angles of the drawbar.

Re: CAT 14M3 Motor Grader
 

Nice work Ari ..3D cad can be very challenging at the best of times .your first grader build inspired me to build one as well..Your work blows me away .mine has been coming along fairly well and always trying to do some upgrades and details ..heres a vid of it doing some snow work ..

Re: CAT 14M3 Motor Grader
 

Hi guys, it's been a while since last update.
I've been drawing the cab and the engine enclosure, and those parts I was thinking to 3D print. You who have used 3D printer for parts like those, how would you print them ? Do you print it wall by wall flat the build plate, or how would you do it ?

I got some machining done also. This is the rear sub frame for the ripper:)

I was trying to upload these pictures from Photobucket, but no matter what I did they showed up on the original size:mad: I give up, switching to Postimages.

Re: CAT 14M3 Motor Grader
 

How I'd print the cab would depend on the size of it. IF it was small enough I could get in on my printer in one shot, I'd try it that way first.

Re: CAT 14M3 Motor Grader
 

Thanks man !
That would be the easiest way, I'm just a bit bit worried about how the window openings will turn out.

Re: CAT 14M3 Motor Grader
 

I made the first side wall for the engine enclosure. It's quite awkward shape as it get wider at half way and the upper front corners are bevelled, due better rear visibility.

Here is a video of the welding process. It's not this project, but you get the idea.
