ABSTRACT:

TECHNICAL FIELD
This invention pertains generally to power tools and more particularly to an improved cutting tool such as a tile saw and methods for adjusting and operating the cutting tool.
BACKGROUND
Portable power saws such as tile saws are frequently used by craftspeople to cut building materials such as tiles and stone into different shapes and sizes for various applications. For example, craftspeople working on construction and remodeling projects often use tile saws to cut tiles and stone for floors, walls, countertops, and fireplaces. Because on-site tile cutting saves time and money as compared with off-site cutting, many tile saws are portable so that craftspeople can use them at the work site.
FIG. 1
is a perspective view of a portable tile saw
20
, which includes a frame
22
, tile-tray guide rails
24
, a tile-cutting tray
26
, a coolant pan
28
, a cutting-tool mounting structure
30
including an arm
32
, a saw motor
34
, and saw blade
36
. Because tiles are typically made from ceramic or stone, the saw blade
36
is often diamond tipped. The tile saw
20
is shown cutting a tile
38
.
Unfortunately, a craftsperson (not shown) may have to repair or discard the tile saw
20
if damage to the structure
30
, arm
32
, or other component of the saw
20
causes the saw
36
to have an undesirable cutting angle. For example, improperly manufacturing or dropping the saw
20
may bend the structure
30
, arm
32
, or other component and this bend may move the blade
36
out of alignment. Typically, the craftsperson cannot realign the blade
36
without replacing the damaged component. Such component replacement is often expensive due not only to the cost of the part, but also to the “down time” during which the craftsperson cannot use the saw
20
while he awaits delivery of the replacement component. Moreover, in cases of severe damage, the saw
20
may be unrepairable and must be discarded and completely replaced.
SUMMARY OF THE INVENTION
In one aspect of the invention, a cutting-tool base includes a motor mount and a rotatable blade mount that is attachable to the motor mount.
Such a base typically allows one to realign a blade, such as a tile-saw blade, without costly repair or replacement of the tile saw.
