PUSH BLOCKS
Push blocks are simple, yet necessary tools to assist the
operator especially when jointing thin or short stock.
Illustrated are three types of push blocks commonly used in
jointing. Push blocks may be obtained commercially or easily
constructed.
Note: The Jointer is supplied with two hold-
downs for feeding stock.
Push blocks are intended to keep hands and fingers away
from cutting blade(s) while providing the ability to feed
material through the cutting blade(s).
These two items are of equal and important consideration
when building or buying push blocks.
Push Blocks should:
 Maintain the 3" (76.2mm) rule by keeping hands at least 3"
(76.2mm) from the cutting Blade(s).
 Provide stops for fingers should they slip during use.
 Feel comfortable in your hand(s).
 Have a notch or dowels to assist in holding the material to
prevent kick-back.
 Provide enough surface area to hold the material against
the cutting blade(s).
 Be made of quality material that will not crack or splinter
when it contacts the cutting blade(s).
 Be made of material that will not mar or scratch work
material.
 Make the overall use of your machine safer.
Because applications vary and push blocks are intended to
come in contact with the cutting blade on occasion, have
several push blocks available for your application(s).
