Woodpeckers SPT-6 - Super Track 6in. WOODPECKERS SUPER TRACK are great accessories for jig and fixtures because they are a, heavy-duty, general purpose T-Track for a variety of woodworking applications. Super Track has (7) T shaped tracks distributed around all fWoodpeckers' sides. These tracks fit any standard 1/4in fastener such as 1/4in hex nuts, hex head bolts and 7/16in wide oval nuts. In fact it's these vary tracks that make SUPER TRACK so easy to install. Simply drill holes in the work surface, drop in some 1/4-20 hex head bolts and slide in SUPER TRACK. Very simple, very easy. A big advantage bolting from the bottom has over screwing down from the top is resistance to pullout. Bolting from the bottom had dramatically greater resistance to pull out.If you use knobs to lock the hex head bolts instead of hex nuts, you can easily adjust the position of SUPER TRACK.SUPER TRACK can be used horizontally or vertically, on top of or embedded in a jig, fixture or work bench.Custom lengths over 60in; are available by request. For lengths over 60in, a rough estimate of the cost is $1.25 per inch. Special packing charges may apply.SUPER TRACK can be cross cut with any carbide tipped blade. The ideal blade has a negative rake, triple chip grind, similar to a laminate cutting blade. A limited number of cuts can be made with an ATB tooth pattern. Cut slowly, ensure at least (3) teeth are in material at all times and use some kind of lubricant. Specific lubricants for cutting aluminum are available. Shop Woodpeckers' local hardware store.
