Fernando,
I have learned a lot about the Tormek from working with this one tool and the way it is ground. The Lacer grind for a turning skew is a combination of a radius ground skew for about two thirds of the width and a flat straight grind on the remaining third of the width. The combination creates a very versatile tool. The combination also prevents the Multi Jig from working properly.
In fairness to the Tormek engineers, I will add that the Multi Jig, while it is very versatile, was never designed for this combination grind. As with any Tormek jig, there is a range of tools which fit the jig very well, an extended range of tools which barely work with the jigs, and some tools which are outside the range of the jig and do not work at all. For example, my everyday kitchen knives, from my paring knives to my chef's knife all fit the Tormek jig nicely. The Small Blade Holder extends the range to small blades with substantial handles. For small blades with small handles, a few of us on this forum went beyond the handbook and devised our own jigs. (Today young people doing this kind of thing with electronic devices call it "jailbreaking".

) Herman's platform is an example of the best of these "jailbreaks".
The method which I found worked very well for me is essentially the same method that Alan Lacer uses, except that it is done with a Tormek instead of a dry grinder. Lacer calls this freehand sharpening with a platform. In this case, I use the Torlock platform with the opposite edge facing the grinding wheel. I consider this not within the conventional handbook technique, however, not quite a jailbreak.
The lesson here is that the versatility of the Tormek is not limited to handbook technique. The handbook is an excellent starting reference guide. It works best when paired with user imagination.
There is also a size constraint with the Lacer skew. At 1 3/8”, it does not quite fit into the closed seat of the Multi Jig. That is a minor issue.
The Lacer grind works well with smaller skews. Before I purchased the Lacer skew, I reshaped a one inch skew to Lacer grind with my Tormek. I like the new grind. In my opinion, the difference is worth the time spent on this one time operation.
Some turners would see the large Lacer skew as too heavy and large. I see the weight as providing stability. I plan to turn forty table legs for my grandchildren's school. The large, stable tool should prove very useful in turning evenly tapered legs.
I will keep you posted.
