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..
Need to make some locating slots for these three fingers from my normal sized steady
Used the milling machine and bolted the disc to my rotary table to index at 120 degrees
Cut one flat edge
Starting the base from a part from an old lorry ..
Which fits here
Cut a slot in the base to fit the brake disc
Cutting the bell off the disc
And here we are, nearly done ... need to weld the two parts together
A mock set-up to see if it all looks ok
