I have some 5" SS pipe that needed to be cut .... pref square !!
So I needed a large fixed steady for the lathe ... an old rear brake disc and an old lorry part for the base. Both parts are cast steel which is very nice to machine.
Cleaned the brake disc up a little to get rid of the rust ... it's a rough quick finish, will tidy later..
