Concrete lathe spindle

As suggested by Pat Delaney, I have machined the spindle parts out of scrap. The spindle measures 350 mm long and has a through bore of 70mm. It is turned from an old piece of hydraulic cylinder.

As you can see I have cut a nut and washers. The thread is 76x2mm;a hybrid size!  The spindle bearings housing is an old caterpillar engine wet liner.

The bearings are truck taper roller bearings.
You will note I have made everything as big as I can find materials. I intend to build at least a one meter Bc lathe with a swing of about 400mm so I can machine automotive brake drums and clutch flywheels.
