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.

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

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'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. https://i327.photobucket.com/albums/...ps6x4wbkaa.jpg http://i327.photobucket.com/albums/k...psqzohcegn.jpg |
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 :)

I got the centershift cylinder and few brackets done. On the last pictures you can see some extreme angles of the drawbar. https://i327.photobucket.com/albums/...ps98yswrmi.jpg http://i327.photobucket.com/albums/k...psvfdgsbnh.jpg http://i327.photobucket.com/albums/k...psg0xlnbzl.jpg http://i327.photobucket.com/albums/k...psi78tu2rd.jpg http://i327.photobucket.com/albums/k...psgmrwovqi.jpg |
Re: CAT 14M3 Motor Grader
