HOW TO CUT DUALVEE TRACK
DualVee track is made of either AISI 1045 carbon steel or AISI 420 stainless steel and is either hardened or unhardened. The surface hardening process leaves dark discoloration marks on the vee surface.
The best method for cutting DualVee track to your desired length is to use an abrasive chop saw. There are many types, but an abrasive disk saw will cut right through the steel. If you don't have an abrasive chop saw, and relatively few cuts to make, you can use a simple hand hack saw. Another method for cutting would be to use a milling machine and a carbide end mill. The milling machine is very useful for precisely trimming the ends.

HOW TO DRILL DUALVEE TRACK
The heat treatment on the vee surfaces penetrates a little beyond the vee onto what we call the track heal. This is the longer surface with the embossed lettering. You will see that most of this area is unhardened. You can drill your mounting holes into this section very easily using HSS (high speed steel) drill bits, or anything harder like cobalt or carbide. When drilling, some of the material may be somewhat harder than the soft heat treated area. If heat is a problem, use some coolant and feed the drill slowly. DO NOT USE A HAND DRILL (Cordless). To safely drill the track, make sure that the track materials is securely clamped in a vise. Use a drill press or a milling machine.
You can drill through holes in the track and use bolts to attach it to a base with threads. Another idea is that you can drill and tap threads into the track, and then attach it to a base with through holes. This works great if you want to hide the bolt heads in a counterbore.
