1 Table Saw Alignment And Maintenance

2 Overview Step 1 Get the saw clean and safe and your tools ready Step 2 Set the blade stops at 45 & 90 degrees Step 3 Align the blade to the miter slot at 90 degrees Step 4 Align the blade to the miter slot at 45 degrees Step 5 Align the rip fence to the miter slot Step 6 Align the miter gauge at 45 & 90 degrees to the blade Riving Knives vs. Splitters

3 Step One - Safety SAFETY FIRST Before you start the alignment! Unplug the power cord and test the start button Remove the belts (if possible) it makes rotating the blade easier Make sure the arbor washer is clean and mount the blade

4 Step One - Clean #1 #1 #2 #1 Routine Maintenance Clean the worm gears with a fiber or brass brush and lube with a dry lube product (#1) Use light machine oil sparingly on the adjustment shaft bearings (#2) Too much oil attracts dirt and sawdust

5 Table Saw Alignment Richard Hicks on May 28, 2018 Step One - Clean Table Saw Tops I use Johnson s Paste Wax to protect my cast iron tops

6 Table Saw Alignment Richard Hicks on May 28, 2018 Step One - Safety Zero Clearance Insert I use a Leecraft DL-1U insert on my primary saw Heavy duty, high density phenolic Anti-lift pin on the front, four leveling screws and a side adjustment screw Recessed slot for initial saw blade cut $28.95 at Hartville Tool ($24.61 with our club discount)

7 Table Saw Alignment Richard Hicks on May 28, 2018 Step One - Tools Alignment Tools (Deluxe Set) A-Line-It Deluxe kit 12 Plastic drafting triangles (45/90 degree) Toothless alignment blade Wixey digital angle gauge

8 Step One - Tools Alignment with the A-Line-It Deluxe Kit Dial indicator and tips Mounting bars Instructions for drill press, table saw and router alignment From In-Line Industries - $ from Woodcraft

9 Step One - Tools Wixey WR300 Digital Angle Gauge 0.1 degree resolution Magnetic base Backlit for easy reading $29.84 at Hartville Tool ($25.36 with our club discount)

10 Step One - Tools Alternative Alignment Tools Dial indicator clamped to the miter gauge Block of wood with a screw for measurements with feeler gauge

11 Table Saw Alignment Richard Hicks on May 28, 2018 Step Two - Saw Setup Two Table Saws Primary saw is a Delta Contractor Saw with 32 Unifence Secondary saw is a Delta Unisaw with a 52 Unifence Leveling and aligning the saws to each other was an EXTREMELY frustrating job! I probably wouldn t do again!

12 Step Two Setting the 90 and 45 degree stops I use the Wixey digital gauge to adjust the blade angle You can also use a drafting triangle I don t rely on the built-in stops (sawdust can cause an error) I adjust my stops slightly past the 90 and 45 degree settings First set the Wixey gauge to zero on the saw table

13 Step Two Setting the 90 and 45 degree stops Attach the gauge to the left side of the blade (if you have a right tilt saw) Adjust the blade to 91 degrees and adjust the stop Readjust to 90 degrees for use

14 Step Two Setting the 90 and 45 degree stops Attach the gauge to the left side of the blade (if you have a right tilt saw) Adjust the blade to 44 degrees and adjust the stop Readjust to 45 degrees to use

15 Step Three Alignment of the blade to the miter slots Set up and measure from the left side if it s a right tilt saw Make a small mark on the blade at the front of the saw Set dial indicator to zero

16 Step Three Alignment of the blade to the miter slots Rotate the blade to make measurement at the back of the saw Move the dial indicator to the marked spot If it doesn t read zero, recheck the measurement Adjust the trunnion (or table) as necessary

17 Step Three Trunnion adjustment on a contractor saw The trunnion is mounted to the table with 4 bolts (my saw has adjustment pals installed) Loosen three bolts and leave the fourth bolt snug Adjust by rotating the trunnion (use the pals if you have them) Tighten the bolts and recheck the alignment until the difference is zero

18 Step Three Trunnion adjustment on a cabinet saw The trunnion is mounted to the cabinet frame and the top is attached to the cabinet with four bolts Loosen three bolts and leave the fourth bolt snug Adjust by rotating the top Tighten the bolts and recheck the alignment until the difference is zero

19 Step Four Alignment of the blade (at 45 degrees) to the miter slots Set up and measure from the left side if it s a right tilt saw Make a small mark on the blade at he front of the saw Set dial indicator to zero

20 Step Four Alignment of the blade (at 45 degrees) to the miter slots Rotate the blade to make measurement at the back of the saw Move the dial indicator to the marked spot If it doesn t read zero, recheck the measurement Adjust the trunnion as necessary

21 Step Four Trunnion adjustment on a contractor saw The trunnion is mounted to the table with 4 bolts The adjustment is made by adding shims between the trunnion and table on the high side Tighten the bolts and recheck the alignment until the difference is zero

22 Step Four Trunnion adjustment on a cabinet saw The trunnion is mounted to the cabinet frame and the top is attached to the cabinet with four bolts The adjustment is made by adding shims between the top and cabinet on the high side Tighten the bolts and recheck the alignment until the difference is zero

23 Step Five Setting the rip fence to the miter slot Put the gauge in the right miter slot Set the gauge to zero at the front of the table

24 Step Five Setting the rip fence to the miter slot Move the gauge to the back of the table and measure the difference I like to set my fence to (away from the miter slot) to allow extra clearance at the back of the blade. This reduces burning and chances of a kickback

25 Step Five Setting the rip fence to the miter slot If you have a unifence, use the adjusting knobs to align the fence Other T-square type fences have similar adjustments Older fences usually clamp at both ends and are difficult to adjust

26 Step Six 45L 90 45R Setting the stops on the standard miter gauge The standard Delta miter gauge has adjustable stops at 90 degrees and left and right 45 degrees Use an Allen wrench to make the adjustments

27 Step Six Replace the original miter gauge I like the Incra Miter V27 Miter Gauge Well made and Super accurate Patented GlideLOCK adjustable miter bar $62.94 at Hartville Tool ($53.50 with our club discount)

28 Step Six Adjusting the miter gauge at 90 degrees Adjust the miter gauge bar for a snug fit in the miter slot The Incra miter gauge has adjustable inserts in the bar The standard gauge can be adjusted by using a center punch and hammer to widen the bar

29 Step Six Adjusting the miter gauge at 45 degrees The Incra miter gauge has adjustment screws in the head

30 Step Six Add a Sacrificial Fence I use either scrap pieces of ¾ plywood or solid wood Make it non-slip with a strip of self adhesive 320 grit sandpaper After aligning the the fence make a witness cut Replace the fence when it gets too cutup or flexible

31 Let s Talk About Riving Knives What Are They? A riving knife is a safety device that s mounted behind the bade and it follows the blade up and down always keeping the same distance from the blade. It s required on ALL table saws manufactured after The law requires that the riving knife MUST be easy to install and remove and when it s installed, it MUST be in line with the blade without any adjustments. What Do They Do? They keep the wood from binding during a RIP cut and causing a KICKBACK. The Same As a Splitter? NO, a splitter is mounted behind the blade at a fixed heigth and MUCH further from the blade
