I should add, that I've tried to sharpen, so far, over 20 1/4" chisels, so I'm confident I can rule out a wonky chisel as being the problem.
I'm still absolutely fed up, but I'm nowhere near the workshop so can't be tempted to tinker further today.
On my drive home, I've been thinking about the problem, and I have come up with the following thoughts about the problems I have encountered so far.
I cannot get over the fact that tightening and loosening the screws on the SE-76 can only introduce a fractional difference of a few thousandths of an inch to the alignment of the chisel, whereas comparatively, the play on the Universal support legs where they fit into the top of the machine is massive. Personally the fact that this level of tolerance is considered acceptable on a commercial product where accurate results depend upon accurate alignment, troubles me greatly. I mean, when the screws are loosened, it's possible to rattle it.
Further thoughts are that I have not been able to determine how much pressure is required on the back of the tool when sharpening. For all I know I could be putting far too much pressure on.
My initial instinct regarding the design of the SE-76 still stands. the gutter, as somebody called it, must be causing at least some of the problems. As there is no way to reference whether the back of the chisel is firmly against the top edge of the SE-76 other than visually, and that gutter can cause the chisel to twist in the jig, then the design is flawed. Yes it will work for plane blades and 1 inch chisels, but. the curved clamp against the top of the chisel means that there is very little to hold the chisel firmly in the correct place.
I'll be honest here, I'm really unhappy. I've taken up a LOT of work time on this, and I think I could have got more accurate results with Japanese Waterstones.
I spent several hours on a Clifton No 7 plane blade correcting the 1mm skew that I accidentally introduced on the first attempt.
On a separate note, I had quiet misgivings about the stone grader from the outset, and my fears have been realised. All the stone grader has succeeded in doing is curve the stone surface so rather than flat it's convex - necessitating a further half dozen passes with the truing tool. My stone is now at 240 mm after 6 months of very little use - it's lost 5mm in the last few weeks. (It lost 5mm when I first got the machine, and then the machine sat idle for 3 months, with very light use until the last couple of weeks) Again I feel a victim of vague instructions - how much pressure is too much? how much is not enough?. Holding a stone freehand against the wheel is bound to negate any accuracy from the truing tool, so I'm feeling that it's another sales gimmick that doesn't do what the sales hype says.
Guys I'm really sorry that this is so negative but I'm just not feeling any love for the Tormek System any more. The only thing that I actually like is the leather honing wheel.
