That sure looks like a NICE running grinder. Good job on the grinder. Also, a good job on the photos. I do like the tracking system - I've put a similar one on my grinder. That video really shows just how smooth the grinder runs - you gonna ENJOY that grinder!
What's the story on the platen? I see it's nice thick at ends, but is thin in middle. That's got to be a repurposed piece of metal..... and I know you're as bad as I am looking to repurpose stuff.
