Tormek Profiled Leather Honing Wheel

The Tormek Sharpening System is ideal for turning tools, but part of the sharpening process is dealing with the burr that forms in the concave flute of the tool.

Jamming the gouge into a piece of timber to break off the burr will work, but the Tormek Profiled Leather Honing Wheels do a better job.

Original Bowl Gouge tip

Here is the tip of my bowl gouge – it has had some sharpening recently, but hasn’t benefited from a really decent sharpening method.  It is a turning tool, so I’m still not going to worry about running it on the Japanese Waterstone, but still, first shaping it on the 220 stone, then redressing the stone to 1000 grit produced a nice surface.

Next, onto the standard leather honing wheel to get a decent finish, then finally a touchup on the new (for my T7) profile wheel to remove the burr and perfect the edge.

Profiled Leather Honing Wheels

There are 2 wheels – a larger diameter one (and I’m referring to the profile here, not the actual diameter of the leather wheel itself!) (6mm diameter), and a second that has been shaped to a V section.  You can get a 4mm diameter one if you typically need a narrower profile.

Leather Wheel Detail

Between these two, I can dress the inside of all my turning tools and carving knives and chisels.  I have oiled them up, then applied some honing compound.

Refined Edge

The outside edge of the bowl gouge – looking a lot nicer.  You can see one facet that I haven’t ground out – it isn’t affecting performance of the gouge (came from when I had a less ideal sharpening method), and I didn’t want to waste good steel to remove it – it will disappear over time as the tool is sharpened (and to a consistent angle because of the Tormek setting system).

Don’t mind the few bits of dust in the photo – I think they are from the new leather profile wheels that I’m still oiling in.

Next to receive the treatment will be my large roughing gouge.  Imagine a roughing gouge with this sort of edge.

Sharp? You better believe it!!

Episode 25 Sharpening Series Watercooled Grinding Stone

This episode looks at watercooled grinding stones, such as the Triton, Scheppach and Tormek. In this instance, a $A199 Triton Wetstone Sharpener is used to produce an edge on a plane blade of HSS.

It also happens to be the last video shot in the old shed, so a bit of nostalgia there!

 

Sharpening demo at Carbatec

Carbatec are going to be running a sharpening demonstration morning on Saturday April 5 from 9:00AM until 1:00PM.

They’ll be demonstrating a a number of different sharpening products and methods, including

Tormek, Veritas, Japanese waterstones , DMT diamond sharpening tools to name a few.  The demo morning is free btw.

If I have a chance, I’ll definitely be heading along.

Tool of-the-Month (February 08)

The tool for this month is the Veritas MkII Honing Guide. Veritas are well known for producing quality jigs and tools, and the MkII Honing Guide is no exception.

The MkII is a significant development on the original jig and although it has been available for a while now, it still justifies being highlighted. It is used in setting and maintaining the bevel angle for edge cutting tools (such as chisels and plane blades).

It consists of 2 main components – the black component is the blade holder, and once the blade position is set, holds it in that position during the grinding/honing process. The other component (silver) (the registration jig) is used to set the blade position so it is honed to the correct angle. Once the blade position is set, this component is removed.

There are a number of advantages of the MkII. First and foremost is the accuracy and repeatability of setting the honing angle. The guide can be used on waterstones, oilstones, diamond stones, and sandpaper (commonly called the “Scary Sharp” technique). It has a large brass eccentric roller which can be set to a secondary position for creating a microbevel.

The setting jig not only controls the amount of protrusion of the blade (ie distance from the roller, which dictates the angle of the bevel), but also keeps the blade square so that an undesired skew is not created.

Here you can see the stop which is dictating the blade protrusion, but also the far side has a fence which the blade is resting against, ensuring that it is square to the roller. The blade in this case is one of my HNT Gordon plane blades (which as you might be able to see, already has a mirror finish).

Once the blade position is set, the registration jig is removed, and you are ready to start honing the blade. I’m going to be doing a separate article/video on various sharpening techniques in the near future, so won’t go into details here.

More recently, extra jigs and modifications have become available for the MkII guide, including a Skew Registration Jig for deliberately (accurately and repeatably) setting a skew angle if so desired.

The Veritas MkII Honing Guide and Skew Registration Jig has been supplied by Carbatec, and continues to prove to be their most popular honing guide.  I’ve had my MkII Guide for quite a while now, and it has proven to be an invaluable tool where it comes to sharpening.  I had the MkI before it, and although it was a good jig, the MkII has proven to be exceptional, and I’ve never regretted upgrading.
