Project Mini Hägglund

[Steinbruchsoldat]

Thanks for the idea, but i decided to redo the whole thing. First i cut everything off:

Found a 3/8" plate with the right size:

Slotted another one:

This is how it`ll go together:

Started welding it up:

Also made a coolant catching thing for the mill:

Finished the new coupler mount:

Coolant is to cool stuff, right?

Tacked it on:

Everything back together:

Then i wanted to start with the bumps:

The lower two should be straight forward:

But the upper ones will cost me some sleepless nights...

But, i also have to add two hydraulic rams to the joint to control the vertical motion. I can probably use them to limit travel too.

A buddy from the german offroad forum told me that i can probably part out his old forklift for the hydraulic stuff, so i set the coupler on hold until i know how much hydraulic rams i get...

First i finished the coolant catch thing today:

I almost can`t work on anything until i get the hydraulics figured out, so i fitted the gas tank today:

Then i finished the shifter:

If everything works out i`ll have the following controls: Small steering wheel for steering on the left hand, shifter on the left hand too. Pedals like a normal car and a joystick for everything else (snow plow) on the right hand:

Bought some steel today:

Thn i made a mount for the front differential:

Added a skidplate:

Finished:

I'll preface my question by stating that I have no experience of welding engineering projects on this scale, so I'm completely in the dark on this point.

In this pic, the two bearing mounts are welded to the base plates, to my inexperienced eye, all the forces generated between the front unit and trailer pass through those two, small diameter, circular welds which have a very small surface area, and I'm wondering if these small surface areas will be sufficiently robust to endure such loads.

 

[Steinbruchsoldat]

Those bearing mounts are designed to be welded on, so the welds should hold up good, either way it`d be a bad design flaw from the manufacturer...

Got some nice carbide tooling and cutting heads today:

Made an arbor for the cutting heads:

Those are some ************* awesome tools:

that looks like an expensive shopping trip!

 

[Steinbruchsoldat]

Well, that stuff is worth more than my whole mill and accessories for it...

Good that i didn`t pay the regular price...
