Guten Abend zusammen,

The steering box is bolted in it's final resting position, which isn't exactly as per the original but because of the components that i am using it was always was going to be a compromise.

The final drives / reduction boxes stuck out too much from the side of the chassis, meaning that the front sprockets wouldn't be inline with the rest of the wheels. I therefore removed material from the castings, first of all with an angle grinder and then I finished them to size on the milling machine.

The next problem was bolting the final drives to the chassis as I had cut the original studs off of the castings. There are six 1/2" UNC threaded holes already in the front of the castings that I can utilise but I need some in the flange area. The answer was to drill five new holes for M16 bolts and then weld bosses on the rear of the flange so that the flange bolt securely on to the chassis.

The output shaft was then reassembled into the casting so that I can position the final drive housing onto the chassis and drill all the attaching holes.

That's all for now folks,

Jon,

Nice to be away from the electrics and back on the tools??

In that last photo - in the background - is that the output of the steering box in the cut out of the hull?

I presume the final drive/reduction box is going to bolt over that?

You have a shaft to bridge the "gap" across the hull to the other final drive/reduction box? I'm assuming the existing shafts are going to be "modified"/adapted to marry up with the steering unit?

To be honest, I liked doing the electrics, it was a challenge, the machining is just the same old same old but it doesn't matter what I am doing, it's interesting.

Yes that's the output from the steering box, the input shaft for the final drive will somehow be attached and final drive casting will cover it. However, there will be a cover that covers the final drive casting, so that it all looks as near as possible as the original did. Connecting the steering box to the final drive on the left side of the hull is the easy side, if it can be called easy, the right side is a completely different matter because there is very little space available between the output of the steering box and the final drive casting. I have a plan, lets just hope that it works.

Evening All,

Today I trial fitted the first final drive unit, it all lined up as anticipated.

The original had an armoured cover over the final drives, obviously my cover won't be armoured but it will hide the castings and make the area look roughly like the original.

The big question is, can I get my welding to look like the original?

Hello Citroen Man,

 

Thanks for the video, no I hadn't seen that before, I would be incredible to find something like that and then restore it.

 

Evening All,

Just a quick update, in truth there's not much to tell, I seem to have spent the last week doing everything other than the tank.

Getting the final drives inline with the steering box took quite a lot of time and I lost count of how many times I had to remove the steering box to make alterations but the easy side is almost complete apart from the drive shaft cover.

The right hand side has been a right pain because of the limited space and the need to have the longest possible splines on the drive shaft. Time has moved on from when I was a full time machinist, had someone brought us a hardened shaft and asked us to machine splines on it, it would have been a no go but I bought a carbide cutter and even my old milling machine made easy work of the job, impressed, I should say so. In my opinion this is still the weak point in the drive chain but time will tell.

I fear that things may slow down even further in the near future as I have some rooms to refurbish in an old rectory.

Evening All,

I have been making the flanges for the final drive housings. On my tank, the covers are really for aesthetics, however the flanges will actually add some rigidity to the area.

                                                        The area concerned on an original tank

My housing profile was always going to be a compromise in order to cover the tractor final drives but in actual fact, it's not that different from the original.

The flanges were made by piecing sections together then welding and grinding them to finished shape.

                    Flange welded onto the hull.                          Final drive housing flange bolted to the hull flange.

Now all I have to do is fabricate the housing cover.

Jon,

This is Tonia's brother Paul, been following this build thread in awe of the skills and determination shown in this project. I was quite chuffed with myself when I built my kit car and like you made my own wiring loom but this build is on a far superior level and with far inferior internet connection. 

Tim keeps promising to bring me down for a look around which would be an absolute pleasure for something who enjoys both engineering and 2nd World War history.  It appears you have broken the back of this project and hoping that the finishing stretch is somewhat easier.

Keep up the great work, it inspires others to give it a try and never believe that projects like this aren't acheivable.

To be honest, not much that I could show you, I have been really busy doing other things that were more important or so I am told. The rest has been a good opportunity to plan the next stage, do some more research and reinvigorate the creative juices, after the Victory show, I shall be back on it.

Jon

Thanks for the reply.

There are more things in life than military vehicles (I am told). Take it easy and succes when you continue.
