Oshkosh Het M1070, M1000

Made the molds using mold putty, came out acceptable. Tried casting with JB Weld, and suprise I have some parts. The parts will clean up with a file and sand paper.

If I have some parts prototyped again I will raise the resoulation. These parts were set on the lowest resoulation for rendering. Although the resoulation does not show in the rendering photo, it will show up in the printed part.

Yes Steve it opens up the possibably of parts ing isn't it

I know what JBweld is but what is liquid metal?

Here is a link that explains Liquid metal.

Thank you for the info. I will stick with JBweld.

wow, for just using jb weld the parts really don't look too bad

[Car5858]

I have to agree Russ, this is what they look like cleaned up. To bad it takes 30 hours to harden before you can file and sand them.

I also tried smoothing out the molds, maybe that will help with finishing on the next one.

I also rotated the pinion mount 22.5 degrees so that the hardware will have more material for threading.

I also attached the swivel connectors.

Just a few steps along, classes start in the morning so I will not be able to work on this much during the week for the next two months.

That's Crazy! what company printed that for you!?

[Car5858]

Zach, the company is https://printaproto.com/index.php I think it was a reasonable rate.

Parts turned out great! Excellent detail and overall look is so real. Combination of high-tech (3D printer), low-tech (JB Weld), generous supply of imagination and great workmanship, and we get to see top-level modelling. Well done!

Thanks for the kind words Ken.

I got a package in the mail the other day, RC4WD Dirt grabber tires. Still waiting on the rims.

My Dad is out of the hospital and is starting on the rims in the morning (weather permitting).

Hopefully in a few days I will have some more photos to post.

[Car5858]

The Stamped rims came in from RC4WD today (one bolt missing). Yes I could not resist the desire to see some tires and rims on this thing.

Mounted the tires on rims, there must be a secret to this part that I haven't figured out so far. The tires wobble slightly side to side as they roll, but not the rims.

As for the rest of the covers I am waiting on more JB weld to arrive. I did find out the hard way about mixing. Not enough hardner and the cover is to soft and flexiable .

Oh well, I will start again in the morning.

That's a bummer! good looking build hopefully the machine will be up and running soon

I understand Clausing bought Atlas and they still provide repair part's, try this site.
http://www.clausing-industrial.com/service-std.htm Hope this help's!
Later, Neil#2 aka doodlebug.

[Car5858]

Thanks Neil, I have talked with them on the phone already. They are searching the warehouse for the part.

So far the repair is holding, we will see how it holds up under a load.

Thanks everyone.

[Car5858]

Well no luck on repairing the teeth, or finding a new part. I was able to lock the cone pully to the spindal shaft. Just reduces the options of spindal speeds, we can deal with that. Now we are waiting for the heat wave to pass.

I did get some parts in, pinion bearing covers. I did not think that the abs plastic would hold up to well, and there was an alignment problem. So I redesigned the covers and had them made by the students in the class. One cover was rejected as incorrect.

After deburring and fitting to the covers I drilled the mounting holes. IT went togather pretty nice.


One step closer

[Car5858]

Small update, still awaiting parts maybe they will be finished soon.

In the meantime I designed an 8-71 Detorit in 1/16th amd 1/14th scales.
I have all the parts drawn but still need to dimension them.

One question that I have not been able to answer is how the A/C compressor is mounted.

If any one has some input please feel free to advise me. I was going to post some pdf files but they are to large to post so here are some screen shots.

Your ability to build aluminum parts with hand tools is second to none.
I'm inspired to attempt making parts I would not have in past. Your parts show what a artist you are.

I'm convinced now that those how call Picasso a artist have not seen your work! Joe

[Car5858]

Thanks Joe

I have about 2 1/2 years with the Het and they do not come stock with AC in the models we have. The Super Het M1070A1 does but I doubt we will see those for years.

[Car5858]

Yes that is true. My cousin was Co of transportation Btl. He was the one that got me interested in these trucks. Hopefully I will be able to some more work on this one when Classes let out for the summer.
