I have used the DBS22 on about 10 bits from 4 to 10 mm. Took me a few hours but getting the hang of it. Now for the but! I can shape the four facets BUT I can't get the primary facets to meet at a point. I can increase the secondary facets so that the primary facets become a narrow strip but a chisel point remains. If I go beyond this then I grind out the primary facets. Where am I going wrong?

General Tormek Questions / Maintaining the wet stone wheel
November 12, 2013, 07:12:18 AM
I have spent some time shaping and sharpening chisels and hand planer blades with ok results. I used the supplied stone to refresh and alter the grit of the wheel. I am surprised to find that I seriously altered the shape of the angle of the surface of the stone by my actions. I concluded that the grinding stone is quite soft and I needed to be very careful to apply even pressures to the surface or it quickly wore unevenly. This was identified by putting a set square across the surface of the wheel. I used the truing tool to good effect. A little more shaping and sharpening and the wheel needed re-truing! I estimated that I removed about 3 mm with the truing tool, and the water bath was carrying a lot of suspended grey sediment. At this rate I'll need a new wheel sooner than I expected!
My questions:
Could it be that the the pressure I applied across the surfaces being sharpened was too heavy and uneven?
Can the surfacing stone grind the surface out of square if pressure is applied unevenly?
I was using the square edge jig and it was not good enough to place the right hand side of the blade against the jig and tighten the knobs. I needed to measure with a set square and tighten carefully. Then I needed to ensure that the finger pressure was even across the blade. If not, the the sharpened edge was soon out of square. Is this a correct conclusion?
I assumed that if I was using a jig and a rigid support system then I could set and forget and go at the shaping and sharpening. Is this an unreasonable assumption for any of the Tormek jigs?
PS. I like working with the water cooled system. It may be that when I have my tools in good order and settle down to resharpening then I will have less of the problems I have described.
