Okay, so I have an old cheap craftsman table saw, which I use for my small cozy garage wood shop. Now it only have a rip capacity of 11''. I need to make a new rip fence so it can rip up to 26''. So, I will show you how to make the actual fence, with JB weld, a 2 part epoxy for metal and other materials, rubbing alcohol, sand paper, and your metal.

Step 1: Cut Your Metal
You can free hand cut your metal w/ a hacksaw, or use a vise like I did to cut you metal your dimensions.
Step 2: Mix Your JB Weld
FIRST sand the paint of your metal, and use rubbing alcohol to get rid of any oil and dirt. Mix your JB Weld on a piece of scrap wood, or card board squeezing out equal parts of hardener, and resin. Mix for like 1 minute, until a little gray color appears, and apply your JB Weld to the bare metal.
Step 3: Clamp It, Square It Up and Your Done!
Use clamps to clamp the fence to the table. and use a clamp on the joint to really give it some strength, and use a square to square it up, and wait 24 hours. Then make a set of rails for your fence to ride on and your done! Good luck!
