The Distinction Between Sharpening and Buffing

Sharpening a chunk of metallic removes a reasonable quantity of fabric utilizing coarse to medium abrasives in phases. The piece can have a brushed look and you’ll not see any reflections in it. Sharpening removes scratches and floor imperfections too deep for buffing compounds. For those who run your fingernail over a scratch and it will get caught, then it’s best to polish earlier than buffing. The important thing to sharpening is eradicating simply sufficient materials to make the floor even.

Buffing removes very small irregularities and makes the floor nearly completely easy by eradicating asmall quantity of metallic. Like sharpening, buffing is finished in phases from coarse to high quality. Buffing compound grits are so high quality that you just won’t be capable of inform the distinction between compounds by really feel. Their distinction in efficiency, nonetheless, is important.

What Are “Chopping” and “Coloring” Compounds?

“Chopping” compounds are coarse and can take away a good quantity of fabric shortly. The primary phases of buffing could possibly be known as the “chopping” phases.

“Coloring” compounds are extraordinarily high quality and end result within the mirror-like shine which is the results of an nicely executed buffing undertaking. The ultimate stage of buffing could possibly be known as the “coloring” stage.

Apply Makes Good!

In case you are unfamiliar with any of the steps, we strongly suggest that you just observe on a scrap piece of trim. Keep in mind: you may all the time take away a bit of extra metallic, however you may’t put it again.


Leveling and Sharpening (Smoothing) The Steel Floor

Examine all items earlier than buffing to find out if any prep work is required. You will have to take away all rust, dents, excessive spots, and deep scratches. The next sections will clarify the way to take away these and different imperfections in preparation for buffing.

Dent Removing

Generally it’s attainable to revive a dented piece of stainless or aluminum trim to its authentic situation. Use a Trim Hammer and Anvil identical to you’ll for dents in physique work. Begin on the exterior of the dent and work your manner across the exterior of the dent and regularly inward in a round sample. This may shrink the metallic again to its authentic form. It’s higher to make a number of gentle passes and work slowly than to attempt to take away the dent with a number of heavy blows.


Subsequent use a high quality file (akin to an ignition level file) to knock down any excessive spots, being cautious to not take away an excessive amount of materials. Examine your work to verify it’s as easy as attainable and, if vital, use the trim hammer to deliver up any low spots, then repeat the submitting to take away any excessive spots.

Sanding/Sharpening by Hand

As soon as the piece has been flattened with the trim hammer and file, sand the realm with 220 grit sandpaper to take away the file marks (320-600 grit for exhausting metals). Smooth metals like aluminum require little work, whereas tougher metals akin to stainless-steel will take extra time. In some instances hand sanding could also be all that’s wanted if not think about using an expander wheel, greaseless compounds and/or abrasive rolls.

Expander Wheel

Additional smoothing the floor at this level will save substantial buffing time. An Expander Wheel Kit combines submitting and sanding into one step. It’s best for bigger items like grill trim and hubcaps. Work from coarse belts to high quality; no less than 220 grit for tender metals and 320-600 grit for exhausting metals. NOTE: It’s higher to start out with an abrasive that’s too high quality relatively than too coarse. For a smoother minimize on metal, and leveling aluminum or different tender metals apply Grinder’s Grease (#13119) or Tripoli Compound (#13135) on to the spinning belt.

3M Trizact Belts on Your Expander Wheel

Further smoothing will be executed with the 3M Trizact Bands, available as a set of 5 (#13159). The exact construction of the Trizact abrasive delivers quick efficient chopping and so they final 2-5 occasions longer than common abrasive bands. They resist loading even when used with aluminum too.These bands are corresponding to 100, 200, 400, 700, and 1200 grit.

TECH TIP: For barely contoured surfaces, use the Finishing Belts (#13139) which mix the cleansing and metallic conditioning energy of Ending Belts with the ease-of-use and velocity of the Expander Wheel.

TECH TIP: Smoothing tender metallic surfaces previous 220 grit and exhausting metallic surfaces smoother than 600 grit lessens the necessity of Tripoli or Emery Compound and velocity the buffing course of.

Greaseless Compounds
When sharpening extremely contoured surfaces, use Eastwood’s Greaseless Compounds (80 grit – #13129, 120 grit – #13194, 220 grit – #13131, 320 grit – #13132). When utilized to a devoted spiral sewn or unfastened part buff, these compounds convert your buff to a versatile sanding wheel. Greaseless compounds will also be utilized to mini buffing wheels, goblet and facer buffs, or felt bobs. To be used, comply with the directions on the Greaseless Compound labels.

Abrasive Rolls
Abrasive Rolls in each cylinders and tapers in 80, 120, 240, and 320 grits can be found to be used along with your Excessive Velocity Pneumatic or Electrical Die Grinder. The Mandrels for these rolls can be found in lengths from 2 3/4″ to six″ lengthy. We suggest utilizing the shortest mandrel that may attain. The cartridge rolls are greatest used with gentle aspect stress, letting the spinning abrasive roll do the chopping relatively than extreme aspect stress.


For assist selecting a wheel and compound seek advice from this chart.

Mounting the Buffing Wheel
Connect the buffering wheel to the buffering motor spindle, ensuring that it’s mounted securely between the flange washers. When mounted correctly, the highest of the wheel ought to spin towards you and down when the buffing motor is working. NOTE: Wheel stitching orientation is of no consequence to wheel efficiency or sturdiness.

Making use of Compound to the Buffing WheelWith the buffing wheel connected and the motor working, gently contact the suitable tube of compound to the face of the wheel for one to 2 seconds. Apply the compound barely beneath the centerline of the wheel. (See illustration at proper)

NOTE: It’s regular for the compound to seem like dried out. The compound consists of a graded abrasive in a tough wax binder. Theheat from contacting the spinning buffing wheel floor will soften the binder and the wheel will choose up the compound.


Drawback Attainable Trigger: Corrective Motion
The Wheel Turned black That is regular. No motion wanted,
Metallic Construct-up On Wheel That is regular particularly when buffing tender metals like aluminum and brass. Finally the wheel needs to be cleaned utilizing the Buff Rake (#13120) to keep away from galling the floor.
Again Streaks On half being Buffed This often signifies extreme compound utility. Apply compound usually however sparingly.
Scratches/Pits Are Nonetheless Seen Even After Last Buffing

Even extremely polished surfaces have high quality scratches. Most of those will be eradicated by making your final move with the course of rotation.
If deeper scratches or pits are seen, it often signifies that sharpening and buffing steps have been all executed in the identical course thus disguising the deeper imperfections. All the time change the angle of assault by 90° (or as shut as the form of the half permits) as you’re employed by successively finer grit abrasives and compounds to guarantee earlier grit traces are eliminated.
