Well, here it is now, since first posting this original post. All up I think this stage of the build will take about 20 hours, maybe 22.
Below is the front steering mechanism which I have just added. You can see how the cogs work the rack which, in turn, will turn the front steer-wheels left and right.
It's fairly complex and has a lot of moving parts when finished, all of which need to be constructed correctly or it won't work properly.
That's impressive! Good job!!!
It's coming along well.
