Step#1 Start by cutting two pieces of 3/4 stock, length and height to your need or liking.
Step#2 Lay your stock flat on your table saw and Cut a 1/8 kerfs the length of both pieces of stock. The depth of your kerfs will be determined by your T-bolt. You may even use a bolt but you will need a bigger kerf.A Dado blade router would come in handy for a wider kerfs or groove.
Step#3 Glue together the two pieces of stock with the two 1/8 kerfs facing each outher.Avoid slipping when doing your glue -up.The two pieces will tend to slip past each outher.I use a 90 degree corner of some kind and clamp and pin nail the two pieces together.
Step#4 You will need one more cut it will be in the top of your fence. The width of the cut will be determined by the diameter of your T-bolt. You can make the cut in the table saw or router.
Step#5 Making the stop block. The stop block is simply two pieces glued together 90 degrees. They can be made from the same 3/4 stock you used for the fence. Lay the stop block over the fence to determine the position of the hole for the T-bolt. I leave one side of the angle about an 1/8 of an inch shy of the surface the fence will lay on.
You can make your fences out MDF,Hard rock maple etc…...I have used this fence design for router tables, Drill press, Miter gage the sky’s the limit hope this is helpful Chipy.
