Most jigs require one or the other of all the above. Agri-Supply in Garner carries nuts, bolts, washers, locking nuts, carriage bolts, BY THE POUND. This sure beats the heck out of going to local hardware/Borg and paying a buck for one bolt when you can buy them by the pound. They also carry a piece of HDPE that is 1"X10'X3/8" thick for about $7.00. This is a wear strip for a tobbacco harvester. They are located above the bolts. It can be sawed or planed to the proper width for runners for jigs. Agri=Supply is located on Highway 70 just west of the intersection with I-40. For T-Track, check Rockler's web site as their 4' track with bolts and nuts is on sale for $10.99. Check as they have a "premium customer" that allows for free shipping on orders over $50.00. If you are going to Charlotte show check out Peacetree for mini t-track that uses 1/4" bolts. It is exactly 3/4" wide and makes good runners for jigs ans sleds.-Bruce
