The drill attachment for the Czechtruder is very nice to work with. I've got the plate c-clamped to the worktop, and i have it set to run very slowly to avoid stripping out the drive screw. I spend more time prepping the clay than extruding with only the stress of the holding the weight of the drill steady while she goes. (Try not to have to use that manly one from the shop; perfectly good lady-sized ones (bigger than a Drexel) are out there )
I do now wish I'd ordered the XXL model of the extruded from Lucy Clay. But, that said, compared to the silver one that costs $30 at any craft store - two of which I cranked right into the trash in a few short months - this LC brand is worth every penny including freight from overseas.
All the LucyClay stuff is awesome - ask for it for Christmas or your birthday, it's sooooo worth it. ;-0) (no affiliation, really I just love their stuff)
