-
- David's description is a little confusing. The arbor is the shaft on which
- the blade is fastened. It may, or may not, also be the motor shaft. In
- most cases, the blade arbor is driven by belt by the motor shaft.
-
- The normal table saw is tilt-arbor. There is no difference. There are
- saws available, however, where you tip the table. I believe the Shopsmith
- series is of this design.
-
- : I am guessing here, but might it be that a tilt-arbor saw tilts the
- : arbor and not the motor (implying that a tilt arbor saw must also be
- : belt (or otherwise indirectly) driven ) or is this mechanically
- : impossible?
-
- On most of the saws, the motor tips, along with the arbor. The mechanical
- design for such a saw is simpler than one where the motor is fixed.
-
- : From this assumption, I would further theorize that normal tablesaws
- : would therefore tilt the arbor and the motor as a unit.
-
- A normal table saw, as used by the people in this group, is a tilt
- arbor saw. So - yes, your assumption is valid.
-
- : OK anyone care to relate this into some commonly acceptable examples:
- : Is the saw arbor of the Delta Contractor's directly attached to the
- : motor? What about the Delta Cabinet Saw? I have seen posts regarding
- : the unisaw which must be belt driven. Which of these qualify as
- : tilting arbor saws? Does the Unisaw qualify as a cabinet saw?
-
- All the saws you mention are belt driven. There are very few table
- saws, that I know of, which are direct drive. I believe they are all
- tilting-arbor design.
