Thanks for reply. I'll make some videos soon.
My tools is result of hard work and many experiments. It started at december 2012 and now, after half year, commercial versions of the tools in sale. Work report was published at pc-3000 support forum, you can see it there (if you have access).
Of course tool not ideal, and it has one huge negative moment - in setting/removing tool process you can touch the surface. BUT! Because material is plastic and machined with high accuracy, after
light touching of the platters they not have new bad sectors.
And then tool is finally fixed you can safely move HSA to non-data area
without any touching MR-heads or plastic tool with surface.
This way is more carefully then other plastic tools like these:

For example, if you need to exchange heads in high density drive such as ST3500418AS or ST31500340AS, tools on the picture above just kill HSA after moving heads over the surface from landing zone in 90% cases. With my tools this job is pretty eazy and effective. And of course low price of the tool is positive moment too.
