sharping question

[sawwood]

 I was thinking as i was sharping my chain and didn't like how it was burring the cutter.
 It is a harbor freight sharping one. Would it hurt if i made a tub to hold oil and pump it
 over the chain to help cool the stone and cutter ? I sharpen a lot as i have a chainsaw
 mill and do a lot of White Oak that is hard on the cutters.

I would think that the motor not being sealed (not designed for) the oil, It could catch on fire or at least ruin the motor.

I sharpen by hand, so I may show my ignorance here.

What stone are you using to sharpen? (Can low quality stones produce burrs?)

Does the stone wobble in the sharpener? (Seems to me that would cause burrs)

Forgive me if my questions are stupid. I wouldn't know a high quality sharpener from a low quality one, but Harbor Freight power tools always makes me nervous. Yeah, I go there a lot for clamps, straps, etc., but I don't trust their power tools. Perhaps their sharpener is better than the worm drive saw I tried. (okay, their cheap metal detector wand works great)

Try making lighter passes and move quickly to prevent heat buildup. Bluing the cutter takes the temper out so the metal will no longer hold an edge. Lubricant will ruin the wheel.

as sawguy said,go lightly on the cutter should be fine no need for oil

Cheap grinders have smaller grind disk which increase the chance of overheating the cutter to.

I normally use a 4" alundum -38 grinding wheel is about the coolest running stone available ,  crystolon is another high quality grinding wheel composition you may want to try for your chain cutter sharpening applications .

 We have the Harbor freight nick the grinder sharpener. I looked at it to day and looks like I need a new wheel. Our chains are 3/8 063 so what
  type of wheel do I need ?

Others may have their own preferences but I have been satisfied with the Oregon 534-316A, use light passes and keep the wheel dressed.

I do about 3 little "bumps"  or very brief grinds on a cutter, check to make sure it is shiny to the point.  The wheel thickness is the diff. between the chains.  Mine uses the same for 3/8th and .404.  there is a thinner one for 0.325, and thinner for 1/4 and 1/4 pica.  the profile is rounded but off to one side, so a profile gage for dressing the wheel is nice.  and a gage to check you rakers for proper height.  they will often wear to the appropriate height, but if too high, the cutter cannot grab.  you can use any wheel the proper thickness with the proper arbor size.  I use the Stihl wheels, although they are not fancy, but must be good cause they cost a lot...   .  or is that just the name.

The chain needs to be clean before sharpening, pitch buildup on it will load up the grinding wheel and cause burning.

   I use the little 12V Oregon Dremel tool type sharpener powered off my ATV, truck or mill battery. It has a built in guide and I buy the little stones. Mine died the other day and I ordered another but bought a file and guide yesterday to use till my replacement gets here and I thought I was doing good till I cut a 13-16 inch ash stock log. Once in the log about 6-8 inches it starts curving badly to the left so obviously I am not sharpening both sides evenly. I have never been good with a file. I have not bought an electric desk model one as the 12V has worked fine in the field on the saw for me.
