The part broke off for me too. i found the part at http://www.oakcanopy.com/vkp1012-6n.html and put in shopping cart, and chose usps priority mail and the shipping was $4.80. it was delivered within 2-3 days. next time you might select another mail carrier when ordering.

I just went to the site, and it looks like they changed the link. For others with the Victorio or Back to Basics Grain Mill, the nylon washer and replacement nut is at http://www.oakcanopy.com/vkp1012-6n.aspx

Same here. I called the customer service number on the instruction pamphlet that came with the mill. 1-800-688-1989. This put me in touch with the company. It has been sold and is different from what is printed. Focus Electric is the name of the new guys. They can take phone orders for this and any other part. this one is called "Nylon Washer" and is currently part number U 10-47. You can order it for $1.75 with shipping cost at $7.95. You can also mail them a check at Focus Electric PO Box 2780 West Bend, Wisconsin 53095. They have a web site but it is new and under construction. I hate that I have to pay more for shipping then the part but this mill is worthless without it. Any ideas about some other washer or rigged part that would make this work the next time I lose this little ******? Maybe I should have ordered 2! *grins*
