This instructable shows how you can build your very own Catalyst! They can be used for all sorts of things:
+A great gift (or challenge) for your DIY friends and family.
+For teachers, building WikiSeats for a class project makes for a fun and engaging experience.
+Or you can build a WikiSeat of your own.
If you plan on building more than just a few Catalysts, check out the WikiSeat Catalyst Jig2 which lets you build Catalysts even faster!
Step 1: Tools and Materials
+Something to cut steel: chop saw, band saw, hack saw
+Something to file/grind steel: metal file, grinding wheel, Dremel
+Sand Blaster (optional)
+Drill Press (optional)
+Angle Iron 1"x1", 15" length per catalyst
+Primer and Paint (optional)
+Three threaded rods 20" length
+Twelve bolts that fit the threading
+Six large washers
+One length of aluminum corner bead
Step 2: Prepare Materials
+Cut the angle iron into 5" segments. You will need three pieces of angle iron for each Catalyst.
+File down the corners and edges.
+Drill holes with a drill press. (optional)
+File metal burrs from holes.
Step 3: Prepare Jig
+Shape corner bead into equilateral triangles with each side measuring 10.750"
*** It is very important that each side of the triangle is the same length! You will get a lopsided catalyst if this is not right.***
+Screw the washers and bolts onto the threaded rod so they can hold your angle iron in place.
+Make sure the angle iron is centered on the rod and tighten the bolts
