Yes I purchased larger plates from
www.sausagemaker.com
they also sell the grinder.
I use 1/2" and 3/8". (1/2" mostly) so it wont clog. I shoulda bought the 3/4" I think that is the biggest.
I still might get it. I also purchase some extra blades and keep them sharp.
Main thing also is I clean and DRY it after each use, especially the plates and cutter. If they get rusty forget it the thing will be nothing but trouble.
