< 2025-07-06 2025-07-16 >Current status is I have made a metal plate to bolt the layshaft and motor to. With slotted holes for chain adjustment. The plate is bolted to the chassis.
I made the slots in the steel plate on the kitchen-worktop CNC machine, it worked really well. Great machine. It's the machine I always dreamed of having access to!
So yesterday I managed to successfully drive the tractor for the first time with no failures, which is a good milestone.
I need to put spacers on the rear axle, and then some sort of split pin or something to hold the wheels on. And then trim the axle to final length. I was driving it around with no spacers and no split pin and the wheels didn't fall off, so I think the side load on the split pins will be very minor.
And then that's the drivetrain done! Next up would be the steering tower thing. Ideally this would overlap the edges of the chassis, but the steering shafts stick out the sides, I don't think it's convenient to attach anything there. So then what? I think we make it like its own box, and then screw the box down to the top surface of the chassis, and once it's in place fit some steel straps to the sides just to hold it down a bit stronger.
Like the green part here:
Here we go:
The aluminium shaft is just in there to help align it. I still need to make the real shaft that will link up with the steering box input. Then that's the steering done. Nice and easy.
I have ordered some steel for the rear wheel spacers.
So next steps are:
I think Lucy's legs will be too short to reach the pedals if I put it at the closest point that I can contort myself into reaching. So both the pdeals and the seat may need to be adjustable.
Maybe something like this for the pedals:
With some sort of pin to lock it into position. So you can swing it up/back to bring it closer.
