Hugh, do you have a good method for sharpening draw knives? A video on this would be greatly appreciated. Thanks!

@dsheaz see the video apprendre a fabrique and you will see us using a nice wet stone to sharpen the drawknives. It's brief (seconds 9 to 11 in the video) To finish the edge I use a hand-held stone. The angle is very important. Never sharpen the back of the blade (except to remove any ragged burr that is created). You can find more tips in my Recipe Book for sale on my web pages.

Hey Hugh, I didn't see that the backplate was fastened to the studs in the stator during the molding process here. Were you just using a piece of wood? Also, I've been wondering if these studs have a nut welded to them inside the stator so as to make them more stable within the casting?

@dsheaz Yes we used a thick plywood disk with three holes in it to support the mounting studs at the correct spacings and parallel. These were drilled through the holes in the steel plate. You can use the steel plate itself but often it has already been welded to the frame by this time. And it's a pain to have the whole frame involved with the resin casting. You can put/weld nuts on if you like, but I would not say it is necessary to do so as the studs are already pretty heavy.
