I used Gliderite 1435Z 14" 70lb full extension slides. The drawers are 12 inch versions of same. These have been hard to get. I order direct from Gliderite.
The fence is held with Tool Improvements Lock Fence Dogs (http://toolimprovements.net/Lock_Fence-Dogs.html), highly recommended. The fence dogs work with the Rockler, the 8020 and the stock fence.
Looks great! I'm interested in the fence dog/rocker multitrack. Looks like a nice setup.what is the deepest crosscut you can do with it installed in rear holes?
