Unfortunately due to a lack of time we could not do the Great Skew Face Off but it will be done shortly when I get organised.

This is the criteria I will be following for the test.

The test will involve roughing a 250mm x 75mm piece of Red Gum to a cylinder, a peeling cut to form a spigot approximately 25mm in diameter and 15mm long in one end,the other end will be rounded over. as many 12mm beads that the chisel will do along the remaining length.

Should the chisel still not be blunt, the beads will be removed by a peeling cut, the cylinder trued and more beads cut.

The "finish cut" will be performed after the above with the cylinder trued with a roughing gouge. The chisels will be freshly sharpened for this part of the test.

2 Stop watches will be used and the time averaged.

There will be 3 Timed runs and the time averaged.

On the longevity of sharpness test, the time will start from the first application of the tool to the timber.

In the sharpening part of the test it will be timed from having the tool and jigs on the bench to when they are set down again. Jigs will be set at correct settings prior to sharpening but they will not be fitted to the chisels.

Red Gum will also be used for the "finish" test but we will also use Pine as some Red Gum can be real cranky grained.

The chisels will be:

A 1" Henry Taylor HSS.

A 1" Bohler S700 tool steel.

A Carbon steel chisel.

Erns.

Sharpening.

1: Freehand on a Blue Max wheel.

2: Ditto then honed on a Norton combination stone.

3: Freehand on a 120# wheel.

4: Ditto then honed on a Norton combination stone.

5: Woodcut jig on the Blue Max.

6: Ditto then honed on a Norton combination stone.

7: Unijig on the 120#

8: Ditto then honed on a Norton combination stone.

9: On a Tormek with the Standard wheel (grey)

10: Ditto then honed on the leather wheel.

11: On a Tormek with a Black wheel.

12: Ditto then honed on the leather wheel.

13: On a Tormek with the 4000# wheel.

13: Erns method.

This will probably take a couple of days and I need some volunteers to adjudicate and be impartial bystanders.

Other duties will be to keep me lubricated and also time things.

Let me know when, I'm pretty quiet with work at the moment, so can pop down pretty much anytime

I'm very keen to be part of this but about the only date I could make would be one day during August 16-19 :( I'll be travelling or preparing for it before and after then.

Just a query about the test. I'm curious as to why you've included roughing down.

Because it is the hardest on an edge, and some of us do rough down with a skew but generally on softer stuff.

Hi ,
You also have me wondering too.
I realise you can only test so many.

So where is the P&N 25 x 8mm.
My 25 x 8mm. Mc Jing, I just can't go past, but I suppose everyone to their own.
Maybe if the C/Steel is good enough, it maybe better than the H/ Taylor.
I Googled "Bohler " & came up with nothing.

Would have loved to have been there Sat. ? but I also have that Flu going around.

Maybe we could look into this Skew Thing at Down Under. Something different.
Regards,
issatree.

Bohler is here Bohler-Uddeholm Australia - Victoria (http://www.buau.com.au/english/b_1891.htm)

It is already 54 bits of timber.:D

It is more a test of the different sharpening methods on longevity of use.

I feel like a sh*t having asked for tomorrow and not now being able to make it.

Can only say that someone else's needs has to be put first.

Elastrators are a veterinary tool available no-questions-asked through farm supply companies and are not "approved" for use on humans and are certainly not considered safe by the medical community unlike the Burdizzo (http://www.woodworkforums.com/index.php/Burdizzo), another DIY farm-castration tool. However, like most castration devices designed for use by relatively untrained farmers, it is able to provide cheap castrations with a minimum of livestock loss.

That's good to know.
