Topic tags/keywords: tablesaw question

I have owned this Ridgid table saw for about 10 years and have always wondered what the cream colored insert in front of the blade insert plate is and what it’s purpose is.

Anyone know?

My Jet has as a similar thing, only it is yellow.

Jet calls it the “align-a-rip” and they say it is “used for creating a mark that lines up the workpiece with the saw blade. After the first workpiece is cut with the miter gauge, turn the saw off and pull the miter gauge together with the workpiece back. The workpiece must be unmoved and still against the miter fence. The cut edge of the workpiece is pulled over the pad and the pad can be marked with a pencil. Now, when cutting the next marked workpiece, the workpiece can be lined up with the line on the pad and cut.”

IMHO, it is useless, but maybe some think it is beneficial.

That is for you to make markings on. Most use it to mark the cut line of the blade so you can align your cut mark when cross cutting with the miter gauge. To do this, clamp a piece of wood to your miter gauge, turn on saw and cut piece. Shut off saw and after the blade has stopped spinning, pull back the miter gauge until the cut end of the wood is resting over the tan (mine is orange) insert. Draw or scribe a line on insert using the fresh cut end of the wood as your guide. You now know exactly where to line up a new piece of wood, even while the blade is running and the blade guard is down.

I have mine scribed with a knife line for the arbor side (left) of the blade. This will never change unless I readjust the trunnions (in which case I will sand it out and re-scribe).

I have a 5mm pencil line for the right side of the blade. This changes depending on blade thickness, so I remark this when changing the blade. (I lay a 15”+ long straight piece of wood against the right side of the blade and across the insert and mark with a fine pencil). I use this for referencing when keeping the cut-off piece, and for measuring to the fence when adjusting rip cut width while the blade is running. (blade guard down)

If you bevel the blade, you will need to make a new reference line(s) for your bevel cuts.

If you have waxed or sealed the table top, you may have to clean the insert with some thinner or alcohol before you can get a pencil to mark on it.

Note: You can use the straight edge technique to mark the left side of the blade cut, but sometimes the miter gauge fits a bit sloppy. To minimize the sloppiness, many folks get into the habit of bearing on the right edge of the miter slot, or the left side as they slide through the cut. Each is okay as long as you do the same every time. By using the piece in the miter gauge as the “ruler”, you will be aligned for whichever way you do it.

Yup, my manual says the same thing as the posts above:
My Craftsman calls it an:

EXACT-I-CUT
The “yellow” Plastic Disc embedded in the table in front of the saw blade, is provided for marking the location of the “saw cut” on the workpiece.
A. Check Disc. If it is above table surface, place a piece of hardwood on top of it and tap it down.
B. With blade 90° (square to table) crosscut a piece of wood.
C. Pull Miter Gauge back until wood is over Disc. Using a sharp pencil, mark a line on Disc.
D. With Miter Gauge in right hand slot, follow same procedure and mark another line on Disc.
E. These lines indicate the “path” of the cut made by the saw blade.
F. When cutting the workpiece, line up mark on workpiece with line on Disc.

in the days of cut-off sleds (great idea) who uses the miter gauge for 90 degree cuts? Just wondering.
