It's a standard Taiwan 3HP cabinet saw... aka Grizzly or Jet or many others, but yes it's an after market fence, a Shopfox. I needed something more accurate and solid than the original that came with it. I got this fence 10 years ago, attached the quartersawn birch to it and never looked back. Only once did I have to readjust it slightly in all those years. When you toggle that handle in front, it locks both ends of the fence to the rails, so you get a pretty solid accurate fence.
I do mill small logs in my shop, 8 inches dia and under, and less than 5-6ft long. I start on the resaw bandsaw (with outfeed table to support log) to slab off the sides and then mill into planks. Often I stop there... but occasionaly depending on the wood I will run them through the planer, jointer and then tablesaw to get them semi-cleaned up and THEN sticker them.
