MPE – 24M Motor Grader Build
 
Hello Fellow RCT&C Forum Members and guest.
In Respect to Freddy Gear Drive and what he has created here with
this forum I am dedicating this 1:16 Scale 24M Motor Grader build in
his honor. The CAD work is about 75% finish. The time in this build
will be (has been) long and expensive but it is coming together – slowly.

In Freddy’s honor…

Looks great. The 24M is a big one:)

Nice thought to dedicate this build for Freddy´s memory.

What an entrance:eek::eek: Your dedication of this build to Freddy is appreciated by all.

Now for some ??? What tires are you planning on using or are you going to make them? Hydraulics or actuators?

Keep the pics coming!!

Can't wait until I can draw 3D stuff like that! (Taking 3D classes this spring)

How many are you making:eek::eek: Missed the extras in the background of the last pic!!!

Nice looking work. Looks like 5 axis cnc machine? What kind?

Amazing what can be done with the proper equipment and the will to go at it. I like the small bearings added to the pivot points.;)

Heck of an entrance! Freddy would have dislocated his jaw seeing this! Fabulous results so far. :cool:

Nice work! I am envious of folks who have cnc machines, while I stand over my manual mill for hours trying to make a small part.:D

Good start so far! Cant wait to see more.

Nice work, I'm glad to see someone building a 24. This should be good.

Re: MPE – 24M Motor Grader Build
 
Hey everyone - thanks for your good words. Of all the models that I had built over the years this one is the most difficult by far but is easily my all time favorite!

tc1cat -
The tires are designed by me and are solid core rubber. I cannot take credit for the process because I had paid $$$ to a shop to make them for me.
The plan is for full Hydraulics. Some I will machine myself and some I will have a shop do.

How many am I building? - One maybe two. Parts that are very complex and $$$ I had extras machined, just in case I want to build a few more.

pigeonfarmboy -
Why wait till spring. There is great FREE CAD software that has full function but with some limitation... after 60 parts you cannot save the assembly. I have been using the Pro version for many years and it is really easy to use once you understand the basics. Here is the link for anyone that wants to explore 3D computer design software:
http://www.ptc.com/products/creo-ele...eling-express/
Are you taking classes for SolidWorks? I also run Solidworks 2012... very powerful but way harder with complex designs.


pugs -
You are right about the 5 axis, not sure on what kind was used because I cannot take credit on the machining. Many of the front axle parts I had paid $$$ to have machined.

modelman -
I know how you feel - I had spent many hours standing where you stand! I'm soooo glad I do not have to do that anymore.

Wow nice bolting. What size are those bolts? Looks a bit challenging doing the ones with the button heads in the blind hole (unless it was done on the machining center)

Re: MPE – 24M Motor Grader Build
 
Wow, that´s beautiful:) Will there be a chain drive to the wheels ?

Good grief those axle housings are phenomenal! I really don't know what else to say, except keep the updates coming, as you progress with this!

I looked at this last night right before we headed out for dinner. The first thing that came to mind was Holy Sh!t!

What you've done so-far is truly amazing to me! Please keep the pictures and info coming!

Very nice looking build.

Re: MPE – 24M Motor Grader Build
 
Wow, that´s top-class! Really inspiring. Those flanges with the ribs seems like a complicated job. How did you do them? Are you using a four- or more axis mill?

By the way, looks like you are using stainless steel. Right?

Stefan

Thanks.
The bolts are M2 x .4 and they were drill and tapped on a machining center.

Yes I am using a chain drive for the wheels. Take a look at this...

Thanks Stefan. The ribs were a problem from the start. It took a long time to find bearings that would fit in the overall design and when I did find the ones that I am using now (Two - 40 x 50 x 6mm), I could not find a place that had any in stock. The design was challenging enough but trying to find a shop to machine them for me was not easy either. When I finally got the parts machined ( on a 5 axis machine)– the shop miss-read the drawing and drilled and tapped the blind holes into the rib pockets. I had to fight to get them to remake the parts for me per the drawing. As you can see I won the fight and the part looks great!

Believe it or not but these parts are all very well machined T6 –6061 Aluminum

The wheel is pressed into the tire.
