Tony, yep same stuff I had mine made out of en36.
Oh just one thing though, to make the shaft diameter bigger at the bearings, have the centre of the bearing bored out, say 1mm to give you a 2mm larger shaft size. There are no oversize bearings available, so hence boring the centre out. There are a few other parts like washers, sleeves etc that need to be bored to suit but again, no biggie.
