o NEVER lift your hand up during a cut!
•
Another tip for making accurate miter cuts, particularly steep ones, is to make an initial cut
about 1/16” over the length needed. Then carefully make a final cut on the layout line. The
initial cut removes most of the waste, leaving less than the blade’s width to trim away. This
greatly reduces the force of the blade on the wood and makes holding the wood absolutely still
during the cut easier.
Never let the wood to be in contact with the miter gauge fence and the rip fence at the same time
during a cut. If the teeth of a blade (or stacked dado) are engaged with the wood, then that wood can
kick out if it cocks at all during the cut.
• For repetitive crosscuts, the Woodshop has a special fixture which attaches to the fence to use
as a stop when repositioning the wood for the next cut.
• To avoid simultaneous contact of the wood with the rip fence and miter gauge, the gauge block
must be set close to the operator’s end of the fence. That way the wood can be slid over until it
butts against the gauge block to size the cut. When the workpiece is moved forward towards
the blade, it must move off the gauge block before contacting the blade. When the cut is
complete, the waste can safely drop to the table without becoming trapped between the blade
and fence.
7.7.1. Large Miter Gauge for the Powermatic Saw
This miter gauge is easily adjusted, therefore it is often out of adjustment.
ANGLE SETTING: You are advised to double check to see that the angle setting is at 90 degrees using a
large carpenter square. In the case that it is not at 90 degrees, or extreme accuracy is necessary, you
need to ask the Shop Monitor to either help you or put you in touch with someone else in the shop that
can.
While the Powermatic saw is used primarily for cross cuts at a 90 degree angle, this miter also allows
you to cut angles as large as 45 degrees on large pieces of wood. You are encouraged to use the miter
saw whenever possible for angled cuts, and not adjust the miter on this saw. If you must cut other than
90 degree angles on this saw, seek help from the Shop Monitor. The Shop Monitor will either help you
or find someone that can help with adjusting this miter.
ACCURACY OF THE TAPE: You are advised to double check the accuracy of the tape measure on top of
the gauge. If it is not accurate, you need to tell the Shop Monitor and take into account the size of the
error if you use it prior to it being readjusted by the Shop Monitor.
USE THE CAPABILITIES OF THE MITER: There is a stop on the miter – one you can use to get accurate
repetitive cuts. There is also an extender on the end of the miter – to be used with long pieces that
hang over the end.
