Ken, I admire your actions.  I've only culled things from my chest of jigs when Tormek made something which obsoleted a jig I made.

[SB]

I've seen a number of posts regarding the question:  

Should one invest in diamond grinding wheels or go with the SG grindstone?

From my experiences with all 6 grinding wheels (SG, SB, SJ, DC, DF, & DE), I have come to believe that a better question is

Should one invest in diamond grinding wheels or go with the SB grindstone?

I find that I use the diamond grinding wheels for harder metals like 

• Wood turning tools (usually HSS)
• Carbide inserts for wood and metal lathe tools
• Drill bits

These were previously sharpened using the SB grindstone.

And, I use the SG grindstone for almost everything else.

So the question to be answered is,

What do you plan to sharpen?

If the tools to be sharpened are harder steels, then go with either the diamond grinding wheels or the SB grindstone.  Do note that the SB grindstone can be regraded, so I believe it is comparable to the DF + DE grinding wheels.  And the SB is lower cost than the two diamond wheels.  

If you are not needing to sharpen tools with such hardness, go with the SG grindstone.

If you need both, my advice is to start with the SG & SB grindstones.  Eventually, the SB grindstone will wear down and need to be replaced.  Then you can consider getting the diamond grinding wheels.


I welcome thoughts and feedback on experiences from others.

Addressed this topic, and resulted in this jig:

Ramiro,

You will probably need to use a Goniostat approach like this one: https://sharpeninghandbook.info/indexJigs.html#Goniostat

I think it would be great to have side-by-side comparison photos.  I believe that you have a microscope with a photo capability.  I can imagine comparing the photos of (for example):

• Chisel ground on an SG grindstone graded using a (600 grit?) diamond plate vs
• Same chisel ground on a DF grinding wheel.  

If you want to do the tests and send me the pictures of the various grinds, I'll put everything together for you. 

Ken,

I am eagerly awaiting your testing results!

Rich

Rusty,

When I use a diamond wheel (which is less often these days as I usually use the SG-250), I use the DF-250.  

Rich

I've seen that a number of US stores have the SJ-250 on sale at  $459, down from $510.

The distance of the SE-77 from the grindstone is based on the angle of the edge being sharpened, not the tool length.  At 30 to 35 degrees, the distance is not much.  

I agree with Ken, especially as I have found the SG to oftentimes be the fastest grinding media to use.  I have all 6 of the Tormek grinding stones, but I often find myself preferring to use the SG.

Those are auger bits and must be sharpened by hand. 

For the skiving knives, you should be able to use:

• The platform approach (e.g., using the SVD-110).  I use this approach when sharpening my Alan Lacer skew which has a similar profile with part straight and part rounded.  I've outlined a process for that at https://sharpeninghandbook.info/WW-SkewLacer.html.

• A straight-edge jig.  I use the SVH-60 to sharpen my beekeeping hive tool which has a similar profile with a straight edge.  The SE-77 will probably also work well.  I've outlined a process for that at https://sharpeninghandbook.info/GT-HiveTools.html.

For the edgers, this is similar to sharpening smaller wood carving tools like veining tools.  I use a simple collar for that.  I've outlined a process for that at https://sharpeninghandbook.info/WW-VeiningTool.html.

For the pattern knives, a platform approach is also probably best.

I have put everything online at:  https://www.sharpeninghandbook.info/indexJigs.html#Goniostat

Richard,

I need to document everything, especially regarding the use of it.  I will post it and the STL files on the SharpeningHandbook.info web site.  Everything will be free for personal use.

May take me  1 or 2 weeks to get everything together.
