Sharpening Wood Chisels & Plane Irons:
As in all freehand sharpening operations, practicing the technique and actual sharpening experience are the best teachers. Sharpening chisels and irons on the bench grinder will produce razor sharp hollow ground bevels which must be followed by honing on a whetstone. Use the following tips to help develop your sharpening skill and success.
1.The chisel cutting edge must be free of nicks and be 90° to the chisel edge. With the tool rest flat, lightly dress the cutting edge if nicks are present or it’s out of square.
2.Adjust the tool rest angle to 25 - 30 degrees to the face of the grinding wheel. Rest the chisel on the angled tool rest and move it laterally across the face of the wheel.
3.Be sure to occasionally cool the tool in water to maintain its hardness.
4.Continue grinding the cutting edge and bevel until the length of the bevel is roughly twice the thickness of the chisel. Remove only the material necessary to achieve the desired bevel angle with a sharp and square cutting edge.
5.This process produces a sharp hollow ground bevel with a small amount of "wire" burr which will be removed by final honing on a whetstone.
Consult woodworking publications for additional tool sharpening information and examples of shop made jigs and fixtures and techniques to finely tune your chisels, plane irons, planer blades, etc.
Refurbishing Screwdriver Tips:
Screwdriver tips often get worn or bent out of shape and must be reshaped by grinding to perform properly.
1.Select a
2.Grind screwdriver tip square and remove all gaps, nicks, and twists in the screwdriver blade. Apply only light pressure to the blade while moving it back and forth across the grinding wheel face.
3.Turn the screwdriver frequently to keep both sides parallel.
4.If ground correctly, the tip should fit completely into the screw slot with no visible gaps.
MAINTENANCE
CLEANING
Avoid using solvents when cleaning plastic parts. Most plastics are susceptible to damage from various types of commercial solvents and may be damaged by their use. Use clean cloths to remove dirt, dust, oil, grease, etc.
WARNING: Do not at any time let brake fluids, gasoline, petroleum- based products, penetrating oils, etc., come in contact with plastic parts. Chemicals can damage, weaken or destroy plastic which may result in serious personal injury.
Electric tools used on fiberglass material, wallboard, spackling compounds, or plaster are subject to accelerated wear and possible premature failure because the fiberglass chips and groundings are highly abrasive to bearings, brushes, commutators, etc. Consequently, we do not recommend using this tool for extended work on these types of materials. However, if you do work with any of these materials, it is extremely important to clean the tool using compressed air.
LUBRICATION
This tool is permanently lubricated at the factory and requires no additional lubrication.
