Now position the double ply panel as
shown in diagram 42. As before you want
to mark out 50mm around the ply. Lightly
mark the centerline of the ply panel so you
can position this edge 50mm in from the
edge of the felt sheet.
With the first sheet cut use this as the template for
the next sheet. You need 2 left hand and 2 right
hand felt sheets in total. On the 2nd cut you should
have the template with the grit face down to get an
exact copy of the first one (diagram 43). The next 2
have the template the other way up with the grit
face facing you. Cut 2 like this and you will now
have 4 sheets ready to go. You can now fix the last
section of ply in place.
