The boring bar system
is the first of three components that make up the Jamieson
Tool System for hollow form turning. The boring bar
system consists of the "D" shaped handle, the dual
purpose boring bar, and the swivel tip cutter assembly.
See the Backrest System and Laser pages for detailed descriptions
of the other two components.
An ongoing difficulty of woodturning
has been the ergonomics of getting the hollowing tool
into the vessel. Traditionally, a turner would
have to bend over the lathe during hollowing. This position
is often hard on the back and can cause damage to back
and neck muscles over time. This problem is further
antagonized by the need for proper tool placement to
achieve a perfect finish. It was this problem
that led Lyle to create the Jamieson Hollow Form Turning
System for safer, in-control hollowing, that is fun,
too. The system creates a rest behind the main
tool rest which simplifies the hollowing process. A
turner can stand beside the lathe and gently guide the
cutter into the vessel.

The bent assembly was originally designed for the jumbo
bar, however, the bent assembly is often used in the
standard 3/4 inch boring bar. The bent swivel
