[CAUT] Work Sharp

[Paul T Williams]

Fred, et.al.;

I read up on the wapin web site about the SurgiSharp and I'm getting very 
interested in it.  I will see one up in South Dakota on Thursday.  Who 
knows, maybe I'll come home with one ;>)

Re: [CAUT] Work Sharp






Hi Paul,
The difference between removing material with a wheel and with a belt is 
enormous. The belt dissipates heat, where the wheel builds it up. With the 
belt, going through the grits, you can get the very final honing done, the 
part we usually do on a bench stone by hand. Fast! No heat to speak of. No 
way you could get to that point with a wheel, at least not any wheel I 
have tried. The final hone is always by hand using a wheel. And then you 
add the leather belt strop and you can go even farther than you could do 
on a fine stone by hand. Again, fast! Doing some fine chisel or plane 
work, leave the leather belt on the machine and strop for a few seconds 
every few minutes of work. As opposed to spending almost as much time and 
effort sharpening as cutting with the tool.
I guess with coarser grits, removing a bunch of material (say, correcting 
a bad bevel), you might dip into a glass of water from time to time, but 
for most use heat really isn't an issue. So the RPMs really are 
irrelevant. Or not in the way you would expect. Try it, you'll like it.

I have a really good bench sander with wheel and belt.  I just want to 
retire this 40+ year-old bench grinder that spins waaaay too fast.

A less expensive alternative is http://www.wapin.com/SurgiSharp_1.htm 
available from our good buddies at Wapin. 
It is a kit which uses a bench sander as its base, and provides for fine 
honing (600 grit belt) and stropping (leather belt with rouge). I got this 
recently and was amazed at how fast and how sharp I could get chisels, 
pocket knife, and blades for voicing harpsichord quills (I can peel the 
thinnest imaginable shaving of delrin with ease, that is if I have my 
magnifiers on so I can see well enough <G>). It's the stropping belt that 
really does it, puts that razor edge on fast and slick, though the sanding 
belt action on a chisel is far faster than a wheel and doesn't build up 
heat. (I still like to hollow grind a chisel as a starting point, but I 
stay farther from the point). And the bench sander is multi purpose. 
That WorkSharp looks pretty cool, too.

Hi List, 

I just found out about a great tool sharpening tool at 
www.worksharptools.com  Check it out!  It would save hours sharpening 
chisels, etc.  and not too spendy.
