|Cutting Paper Rolls to width on a
I did not fancy cutting fax rolls to width with a guided razor blade, so
I used the arrangement shown using a 1947 centre lathe (M type).
The roll is held in a gapped (for measuring 140mm) cardboard ring in the
4-jaw chuck, with just a touch of boiled linseed oil to lubricate the tailstock
centre. A ring of masking tape at about 130mm from the chuck prevents
the roll from unwinding. The two pieces of 2" x 1/4" BDMS are held
vertical by a bolt through the T slots of the boring table. This allows
slight adjustment to the height of the flat-sided knife blade.
With the limited cross-slide travel of most small lathes, it will probably
be necessary to have two fixing holes for the blade at the rear end of the
lathe, to cut the roll in two stages. My picture shows the knife at
the lower level ready for the second part of the cut.
