I started preparing the tie-rod mounts:

Only some minor tweaking with tie-rod mounts and I can weld them to their place. It will be a very tight fit since the diff need to be able to be taken out, but it will fit there.

Once the tie-rod is in it’s place I can make the final piece to the front axle before moving to the tractor frame itself. Front axle work will continue after the first pieces of the frame has been made.
