I am making a part for my monster stepper motor project (moving the gantry on my cnc router table using a repurposed washing machine motor) and I need to bore for two ball bearing races.
I have made a cylinder 55mm x 120mm long with screwed plugs in each end of about 15mm thick. I need to fit a bearing at each end and inside the cylinder there will be a worm that will engage with a gear through a window cut in the side of the cylinder. One bearing is about 45mm diam and the other, which I dont have yet, will be quite a bit smaller.
Now the question is how do I bore the bearing space in each end plug when I dont have any way of mounting it on my lathe saddle for line boring?
