Another 4x4 - I’ll just leave this here….

That's the basic thought process I have as well.

 

It's been indicated to me by someone here in real life that, instead of making standard small long thin Mill style cuts, I could potentially lock the depth up and down and make a whole bunch of drill holes in a row, then, straighten the slot. I'm no machinist so I don't know if that's realistic. Just what I've been told.

 

 

if you use a 1/4" end mill and your vice is rigid, then it might work....  I used to cut these slots in the lathe with an end mill

Was the axle mill work done with the axle still inside the transmission case?  I’d love to see the clamp work of that, if there is any documentation.

it wasn't, but with a bigger table on the mill it could've been done. The shafts were still left in the diff housing

If you have no more than a couple of thousandths of play vertically and horizontally with the spindle locked in place, you might be able to mill a slot with one of these: 

 

You will need a cross slide such as this:

 

I'm not recommending this rather poor way of milling, just showing some ideas.  Typically a drill press holds the chuck using a Morse taper that works well pressing down on a drill bit, but any upward load would tend to loosen it.

[8ntruck 8,332]

  most mill tapers are a larger angle than a Morse taper and they are usuly held in with a bolt that runs through the spindle.

 

 The Morse taper is a self locking taper (steel on steel self locking tapers are 10 degrees or less) and they don't like side loads on the spindle. 

 

I had a 1/4" end mill chucked up once freehanding some sort of odd shaped hole.  It grabbed, rattled the work piece around and in the blink of an eye, shook the chuck out of the spindle.  

 

Fortunately, when it grabbed, it just walked around the hole I started with and didn't grab the work piece hard enough to spin it - thus avoiding a @Pullstart type incident.  Having the work piece in a vice and using the vice as a handle helped a bit.

The drill press I inherited from my Dad was a “no longer good enough” retiree he got free from a friend in a machine shop. In those years, every penny mattered in our household. It has a couple 000ths of movement in the spindle bearing (that I live with) and the chuck is spot welded on. Years ago I asked about the welding and he told me the chuck kept falling off and there was no other way to fix it.

@meadowfield as always you do class A work. And you have all the right equipment to do it. I feel certain that I’m not alone by saying well done and definitely you through this project. Enjoy the ride..

[meadowfield 2,931]

Well it lives!   I left Ewan with an axle bolted on, he’s done the clutch and got it running. 
next step will be a test drive. Might be a run out with C4 and some extreme testing

 @meadowfield Mark did you guys cast those weights?

I'm so dense that I hadn't noticed those. They are very nice!

Weights are copies of the weights shipped here, a friend of ours Shaun made moulds for all the weights and then had a ton of them cast from the old brake discs and drums he's stockpiled for years.

 

They do look really good!

Heres a set painted in the summer

He should reproduce more and sell them on here

Shipping weights from the UK to the US would put pricing pretty high!

I’ll be visiting the UK in January, maybe I can fit a couple of these in my suitcase. NOT!

Excuse me sir. Uuhhhhh. Why does your carry on weigh nearly 200 lbs??

I didn't see the part of them living in England.

That carry on would produce an interesting image on the x ray machine.

I get that there are separate differentials for the front and rear axles, but how did your son solve the front-rear differential?

Frankly, it’s the complication this introduces that would make me opt for a motor-generator and either axle or wheel electric motors!

he didn’t solve it, I did….

 

the rear ratio is 12:28

The front was 8.6:1.

 

but because the front tyres are smaller that makes the interaxle ratio 0.89:1

so I made that using a 20/23 sprocket ratio. 
 

This is our third 4x4 wheel horse, so it’s getting easier each time.

Man your 4x4 tractors would be awesome at ploughing! 

Awesome work tractor looks great!
