I'm a little confused as to why you can't bore the jaws on the lathe itself
with the chuck mounted on the head.

I have no lathe - what I have is actually a toy. I could reach inside by the boring tool
but saddle has no strength to make the boring satisfactory when I work with the metal.
Also I cannot fix the jaws properly - I tried and now the inside is bigger then before
without the improved quality. I need something heavy to do it properly.

Thanks,
