Planer Knife Setting Gauge Planer Knife Setter Gages Knife Setter For Planers Jointers

When you change planer knives, the old knives come out and the new ones go in at whatever height the gib bolts happen to pull them. If one end sits higher than the other, the cutter head cuts unevenly and the finish shows it.

The set contains 2 gauges. Each gauge has a magnet swivel foot that attaches to the cutter head's outside diameter and a depth gauge with a magnet tip that contacts the knife tip. Brand Shunhongyu.

Calibrate both gauges against the existing knife elevation before removing the old knives. Adjust the depth gauge until the magnet tip touches the knife tip, lock the set screw, and note the scale reading. Repeat with both gauges so they match.

Each order ships as 1 set = 2 pcs. Shipment by DHL, FedEx, UPS, etc. SHUNHONGYU supplies various woodworking machine parts. For an enquiry, send your planer or jointer model, the cutter head outside diameter, and the knife tip access so the gauge contact points can be checked against your machine.

If you set knives with no reference, the gauge still works as a matched pair: set both gauges to the same depth gauge reading, then use them to bring each knife to that elevation. The strong magnets hold the knife while you tighten the gib bolts.

What the specification fixes, and what it leaves to the machine:

• Magnet swivel feet — Each gauge has a magnet swivel foot that attaches to the cutter head's outside diameter and holds the gauge in position during knife setting.
• Depth gauge magnet tip — The depth gauge magnet tip contacts the knife tip so you can read the elevation and lock the set screw at that setting.
• Matched pair — The set contains 2 gauges, so you can position one at each end of the planer head and set both ends to the same elevation.
• Calibration against old knives — Before removing old knives, calibrate the gauge to the existing knife elevation and note the scale reading for future reference.
• Gib bolt access — With the gauge holding the knife at elevation, you can tighten the gib bolts while the magnet keeps the knife from dropping.
• Knife pocket cleaning step — Thoroughly clean the knife pocket to eliminate sawdust and pitch before installing new sharp blades in the correct orientation.
• Oil on gib bolt threads — Applying oil to the gib bolt threads can reduce knife movement and increase clamping pressure to prevent the knives from slipping.

What changes on the shop floor when the right part goes back in:

• Set both ends to one elevation. Two gauges let you position one at each end of the planer head, so both ends of the knife can be brought to the same depth gauge reading before you tighten the gib bolts.
• Keep the reference from the old knives. Calibrating against the existing knife elevation before removal gives you a scale reading to return to, so the new knives go back at the height the machine was set to cut.
• Hold the knife while you tighten. The strong magnets hold the planer knife at the correct elevation and level while you tighten the gib bolts, which reduces the chance of the knife shifting during clamping.
• Reduce knife movement with oil. Applying oil to the gib bolt threads can reduce knife movement and increase clamping pressure, which helps prevent the knives from slipping after you set them.
• Start from no reference. When you have no old knife to measure, the matched pair still lets you set both gauges to the same reading and bring each knife to that elevation.
• Clean pocket before setting. Thoroughly cleaning the knife pocket to eliminate sawdust and pitch before installing new blades gives the knife a clean seat before you adjust height.

It fits planers and jointers where the magnet swivel feet can seat on the cutter head's outside diameter and the depth gauge magnet tip can reach the knife tip. Check those two contact points on your machine before ordering.

One set contains 2 gauges. That lets you position one gauge at each end of the planer head so both ends of the knife are set to the same elevation.

Yes. Before removing the old knives, calibrate the gauge based on the existing knife elevation, adjust the depth gauge until the magnet tip contacts the knife tip, lock the set screw, and note the scale reading.

The strong magnets hold the planer knife at the correct elevation and level while you tighten the gib bolts. Position both setting gauges at each end of the planer head with the magnetic tip directly over the knife tip.

Set both gauges to the same depth gauge reading, then use them to bring each knife to that elevation. The matched pair lets you work without an existing knife reference.

Applying oil to the gib bolt threads can reduce knife movement and increase clamping pressure to prevent the knives from slipping. Do this as part of setting the knives.
