This fence is made from MDF with plastic laminate on both sides of the adjustable faces. There are T-slots that mate with carraige bolts for adjustability. The dust collection fitting is a piece of poplar with a 2-1/4" hole
Here's my split fence set up as an edge jointer. The outfeed side is shimmed out with a piece of laminate, and I'm using a 3/4" straight bit.
