<DIV><FONT face=Arial size=2>Hi Gene,</FONT></DIV>
<DIV><FONT face=Arial size=2></FONT> </DIV>
<DIV><FONT face=Arial size=2>Okay, I think I know where you are coming from.
Standard sharpening techniques require you to grind down that full thickness of
the blade.</FONT></DIV>
<DIV><FONT face=Arial size=2></FONT> </DIV>
<DIV><FONT face=Arial size=2>Forget that.</FONT></DIV>
<DIV><FONT face=Arial size=2></FONT> </DIV>
<DIV><FONT face=Arial size=2>I picked up a Norton white aluminum oxide
grinding wheel </FONT><A

size=2> - 60 grit. I rigged up some spacers and put it on my Tormek. The
Norton wheel is slightly smaller in diameter than the Tormek grinding
wheel. I grind it wet.</FONT></DIV>
<DIV><FONT face=Arial size=2></FONT> </DIV>
<DIV><FONT face=Arial size=2>The technique is to simply grind out a hollow in
the chisel blade surface - that way when you go to sharpen it, you are only
grinding on the tip-most quarter-inch or so of the blade. Look at the
photos below:</FONT></DIV>

align=baseline border=0></DIV>
<DIV><FONT face=Arial size=2></FONT> </DIV>
<DIV><FONT face=Arial size=2>Especially the second photo you can see the hollow
that does not get ground on during normal sharpening. Actually, my chisels are
ready for another go at the Norton wheel to deepen the hollow ground out part.
As my hollow exists now, I see that I am grinding approximately 50% of
the full surface. All you need is the very tip of the chisel to be sharpened -
grind it right down with the coarse Norton wheel until you just have a
small unaffected tip.</FONT></DIV>
<DIV><FONT face=Arial size=2></FONT> </DIV>
<DIV><FONT face=Arial size=2>Does that make sense?</FONT></DIV>
<DIV><FONT face=Arial size=2></FONT> </DIV>
<DIV><FONT face=Arial size=2>Believe me, unless you have some sort of grinding
machine that you can mount the chisel in and turn on for 20 hours, you will
never get that full face of a thick chisel like this ground
flat and polished - grind out a hollow and save yourself a zillion hours of
frustration!</FONT></DIV>

<DIV><FONT face=Arial size=2>> How to sharpen. The wet stone has little
effect. They are extremely hard. <BR>> Should I plan on purchasing an
electric sharpener?<BR>> Gene<BR>> ----- Original Message
----- <BR>>> Yes. I have his 1/2" x 1" and his 1/2" x 12". Nice
chisels. I like them <BR>>> also and use them for notching. What is your
question regarding sharpening <BR>>> them?<BR>>><BR>>> Terry
